New Revision of Zero4U (for V1.3)

1

Due to the high demand of Zero4U, we have to manufacture this product faster. We made a new revision of Zero4U, which modified the layout a little bit, and use the SMD version of  XH2.54 connector and 12MHz crystal. Hence these two components do not need to be soldered manually, and the assembly can speed up a lot. The figure below shows the different between the two revisions:
rev2_vs_rev1As you can see, the XH2.54 connector has been moved to the right side, and the IC and crystal are moved to the center now. All USB ports and pogo pins are not changed. The sizing, functionality and pricing of the device are the same between two revisions.
We have the new revision in stock. If you order Zero4U (for V1.3) now, you will get the new revision.

Witty Pi 2: the New Witty Pi

2

Witty Pi has been in the market for more than a year, and it got public praise at the first place. By integrating realtime clock and power management into one board, it allows defining complex ON/OFF sequence with simple script, which is very welcome by users. Today we go a step further, and announce the new generation of Witty Pi: the Witty Pi 2.

What’s New?

First let’s compare the appearance of Witty Pi and Witty Pi 2:

Witty Pi

Both boards have exactly the same size. The two pictures are with slightly different scale, that’s why Witty Pi 2 looks bigger. As you can see, both boards are quite similar. The switch and micro USB connector are not moved in Witty Pi 2, so the acrylic case will still fit.
The obvious differences are the jumpers, there are 4 colorful jumpers now. The newly added blue jumper is to enable/disable the pulsing dummy load on board. If you are using power bank to power your Witty Pi 2 + Raspberry Pi, you may need this pulsing dummy load to keep your power bank alive without drawing too much current.
Also you can see a new 6-pin female header on the top-right corner. This header breaks out some important signals (+5V, LED, RTC_INT, Vbat and Switch) on the board, which makes integration with other boards become easier. You can also use this header to connect an external switch (physical or electronic) to control your Witty Pi 2. Driving an external LED is also an easy work now.
You may also notice the chips are different. In Witty Pi 2, we use much better chips (DS3231SN, AO4616L and SA555), which have much wider operating temperature range. This means your Witty Pi 2 can work outside under much tougher environment. More importantly, the new DS3231SN chip is very accurate (annual error < 5PPM), and it has temperature sensor inside! With the new software you can read the temperature around your Raspberry Pi 🙂
chips
There are some improvements that could not be found in the picture too. Witty Pi 2 doesn’t use the TXD pin any more, hence using serial port for (huge) data transaction will not have any problem in Witty Pi 2. Also the famous “dead lock” problem, which is caused by ungracefully power off, is now solved at hardware level. Without the possibility of “dead lock”, Witty Pi 2 has much better reliability than the old Witty Pi.
Also the battery life has been extended a lot, thanks to the low power consumption of the new DS3231SN chip, which only draws about 3uA current from the battery, when no power supply is connected.
It is quite safe to replace Witty Pi with the newer Witty Pi 2, since Witty Pi 2 has the same interface with Witty Pi,  and Witty Pi 2 can even work on Witty Pi’s software (but not the reverse).

How Much?

Comparing to the old Witty Pi, the material cost of Witty Pi 2 has been significantly raised, mainly due to the high price of DS3231SN chip. As a result, we have to raise Witty Pi 2’s price to 480 CZK per unit (about 17.76 EUR, or 14.88 GBP, or 19.68 USD).

When Can I buy One?

We open the pre-order channel for Witty Pi 2 today, and you can pre-order it in our online shop. We will start the shipping of Witty Pi 2 on about 20th July, 2016.

How About the Old Witty Pi?

The old Witty Pi is now officially retired. We will not manufacture the old Witty Pi any more, unless our customer request to make a customized batch.
 


 
Update on 2016.07.20:
Witty Pi 2 is officially in stock now.
 

Zero4U for Raspberry Pi V1.3

On 16th May we got two news, one is good and one is bad to us. The good one is that Raspberry Pi Zero finally back in stock and it comes with a new feature (camera interface)!  The bad one however, is the PP22 and PP23 testing pads on PiZero has been moved a little bit, which makes our newly launched Zero4U product incompatible with the new Raspberry Pi Zero. The figure below is from the blog post on Pimoroni and it clearly shows what has been changed in the new PiZero.

Difference between PiZero V1.2 and V1.3


On the same day we got a lot of orders on Zero4U. It was because of the fact that, many people finally got a Raspberry Pi Zero without knowing the Zero4U could not work with it. That day was a long, long day, and we updated the Zero4U product page immediately and included warning information everywhere. Also we emailed to our customers who ordered Zero4U on the same day and asked for confirmation before shipping out their Zero4Us.
Also on the same day we decided to manufacture another batch of Zero4U that can work with PiZero V1.3. The first problem to solve is to get a new Raspberry Pi Zero, so we could update our design. Great thanks to our partner ThePiHut, they kindly sent us a new PiZero on the other day. We were a little out of luck as the United Kingdom Royal Mail system didn’t work well in the coming few days, and we finally got the new PiZero after 10 days waiting. We finished the design update on the same day we got the new PiZero, and submitted it to the factory. We did our best to accelerate the process, and then wait with hope. The new design changes the position of two pogo pins so they can connect to the PP22 and PP23 testing pads on the PiZero V1.3.
After more than 2 weeks waiting, today we finally get the new Zero4U back from the factory! We still have the older version of Zero4U in stock, just in case you have PiZero V1.2 and want to get a USB hub for it.

We will make the testings and packaging in the coming few days, and we are expecting to begin the shipping from Thursday (2016.6.16).
Now you can pre-order your Zero4U for PiZero V1.3, so you can get one as soon as possible.
If you still want Zero4U for PiZero V1.2, you can buy it here.

New Product: Zero4U is Coming Soon!

About two months ago, we released our new 7-port USB hub for Raspberry Pi. Today we are going to announce another new product: Zero4U!
As implied by its name, this new product is designed for Raspberry Pi Zero. More specifically, it is a 4-port USB hub for Raspberry Pi Zero and it is designed to build Raspberry Pi Zero with 4 USB ports. This USB hub has 4 pogo pins on its back, and they will contact to the testing pads on Raspberry Pi Zero, if you mount them together, back to back. These pogo pins will establish the data and power connections between USB hub and Raspberry Pi Zero, so you don’t need to solder wires between them any more.

Zero4U: 4-Port USB Hub for Raspberry Pi Zero


The USB hub will take power from Raspberry Pi directly (via the pogo pins), and can output up to 2A current in total for all USB ports. There is a blue LED on board that will work as a power indicator (which Raspberry Pi Zero doesn’t have). Besides each USB port, there is a white LED that will work as data indicator. If you connect USB device to any USB port, its data indicator will light up.

Zero4U gets powered from the Raspberry Pi Zero, and powers all USB devices


Although this USB hub is designed for Raspberry Pi Zero, you can use it on other computers. Just use a USB cable to connect the mini USB port to the up-stream USB port, then it is ready to rock.
The price for this USB hub is 200 CZK (about 7.40 EUR, or 8.40 USD, or 5.80 GBP), and the package also includes the plastic nuts, screws and standoffs for mounting the USB hub and Raspberry Pi Zero together. At the time being, this product is not in stock yet, but we are working hard to make that happen. Hopefully it will be in stock in two weeks. If you want, you can back-order it now, and we will ship it to you as long as it gets stocked.

The New 7-Port USB Hub for Raspberry Pi

Dear friends, it has been a while not having news from us. Today we are very excited to announce our new product: the new 7-Port USB hub for Raspberry Pi 🙂
You may still remember that UUGear’s first product was a 7-port USB hub, which had been launched at year 2014. Comparing to the old version, this new version of 7-port USB hub is compatible to all Raspberry Pi models, including model A, B, A+, B+, 2B and the newly released Raspberry Pi Zero! This USB hub has the same size with Raspberry Pi A, B, B+ and 2B, and has mounting holes for different models of Raspberry Pi.

This USB hub has multiple transaction translators (MTT), which support USB 2.0 high speed transactions (480 Mbps) on each USB port. The 7 USB ports are symmetrically placed aside the 3 edges, giving more room for each USB port and avoid the collision between connected USB devices.
Two mountable pogo pins are also included in the package, and could be optionally used to back-power your Raspberry Pi when back-feeding from upstream USB port is not supported (Raspberry Pi B+ and 2B).
Attach Pogo Pins for Back-Powering Raspberry Pi
The 7 output pins on board could be used to electronically monitor the port usage status. They are in 3.3V level and can be directly connect to the GPIO pins on Raspberry Pi.
Monitor port usage via the digital output pins
If you are interested in more details about this product, you can check its product page, or view its user manual.
The price for this USB hub is 480 CZK (~20 USD, or 17.7 EUR, or 13.9 GBP). It is in stock today and you can order it from our store.


 

Update on 2016.02.29:

We hope you like them 🙂

Witty Pi is in Stock Now

We announced our new product “Witty Pi” about a month ago, and sent out a few samples to some friends that are interested in writing a review. Such as Michael Horne from recantha.co.uk and dbv from forum-raspberrypi.de. The feedback are quite good: all reviewers like the features and think the pricing is reasonable. According to the reviews, the only point that needs to be improved is the software, which is in 1.00 version and has very basic functionality. We will of course improve the software and add more new features, such as setting a repeatable startup/shutdown schedule, a GUI for better interaction or even a web interface for remote settings etc.
We opened the reservation process for Witty Pi since two weeks ago. Until the moment I write this post, there are already 276 units of Witty Pi get ordered. We appreciate the customers who trust us and back-ordered Witty Pi, and we work very hard to accelerate the stocking. Finally, we made it today 🙂  We are happy to announce that Witty Pi is in stock now, and more batches are being produced and are coming soon!
We will ship out the first batch of Witty Pi tomorrow. Below is a picture of the package content:

New Product: Witty Pi is Coming Soon!

It has been a while since our previous post. We were not sleeping, instead we were working hard on new products. Today we are glad to announce that one of our new products: Witty Pi is coming soon!wittypi_0

What is Witty Pi?

It is tiny PCB that could be mounted on your Raspberry Pi (model A+, B+ and Raspberry Pi 2 supported). With Witty Pi, your Raspberry Pi has realtime clock (RTC) and power management on board, and you get some amazing new features:

  1. You can properly turn on/off Raspberry Pi with single tap on the switch.
  2. Raspberry Pi and all its USB peripherals get fully power cut after shutdown.
  3. Raspberry Pi knows the correct time, even without accessing the Internet.
  4. You can schedule the startup/shutdown of your Raspberry Pi.

wittypi_2
 

Why we need Witty Pi?

Raspberry Pi uses micro SD card as its “hard-drive”, and it writes date to it from time to time. If you suddenly cut Raspberry Pi’s power without halting all processes in the system, the micro SD card may lose power during the date writing, and has the chance to be damaged.
Witty Pi adds a power switch for Raspberry Pi, and you can turn on/off the Pi properly, without worrying about the micro SD card. Witty Pi’s daemon process will halt all processes for you, before really cut off the power. What’s more, if you shutdown your Pi with “sudo shutdown -h now” command, or you choose “Shutdown” in the desktop environment, Witty Pi will detect that and fully cut off your Pi’s power after a few seconds. It is true that Raspberry Pi doesn’t consume much power after shutdown, but there are still some. If you have some USB peripherals connected on your Pi, they will also consume power even you shutdown your Pi. With the help from Witty Pi, your Pi’s power can be fully cut off and all its USB peripherals will not consume power anymore. Cool, isn’t it?
The ability to schedule shutdown and startup are also very useful. You don’t have to wait til midnight to shutdown your Pi, or wake up very early to turn on your Pi 🙂
Also don’t forget Witty Pi has RTC on board, it can remember the correct time for your Raspberry Pi. Even without the Internet access, your Pi will know the correct time, because Witty Pi will synchronize the time to your Pi’s system.wittypi_1

When and How Much?

The retail price for Witty Pi will be 380 CZK (about 15 USD, or 13.8 EUR, or 10 GBP). Besides the Witty Pi board, the package also includes a CR2032 button battery, 4 cooper standoffs and 8 cooper screws that can help you to fix your Witty Pi with Raspberry Pi.
The exact date to ship the first batch of Witty Pi is not decided yet, but the reservation process will be opened on our website very soon. Please keep an eye on our website, or follow us on Tweeter, Facebook or Google+ if you are interested.wittypi_4Update on 2015-04-18:
