New Product: RasPiKey eMMC Module for Raspberry Pi

Our new product RasPiKey is released today!

RasPiKey is a 16GB eMMC module designed for Raspberry Pi. It can be inserted into the micro SD card slot on Raspberry Pi and work as a faster (especially 4k read/write) and more endurable SD card.

On Raspberry Pi 3B+, RasPiKey shows much better performance than SD cards (using the benchmark introduced in Jeff Geerling’s blog):

RasPiKey can also be used on Raspberry Pi 4B, however you will need to update your Pi4’s bootloader first. At the time being, RasPiKey gets limited support by Raspberry Pi 4B and doesn’t get speed boost like those good SD cards, its performance on 4B is not that outstanding, however it still has better 4k read/write speed than SD cards.

Updated on 2020.12: Now with the latest official firmware, Raspberry Pi 4B supports DDR52 timing mode, which boosts the performance of RasPiKey, and make RasPiKey faster than SD cards on Raspberry Pi 4B.

Plug and Play

RasPiKey has Raspbian preinstalled, and also provides some tools to make setting Wi-Fi connection and enabling SSH login much easier. It is possible that you insert RasPiKey into your new Raspberry Pi, power it on and then use it via SSH session on your computer. You can enjoy your Raspberry Pi without having another set of display, keyboard and mouse.

Price and Where to Buy?

RasPiKey’s retail price is 520 CZK (about 20.37EUR / 17.53GBP / 22.55USD).

You can order it from our e-shop or you may be able to order it from our resellers soon.

We Now Have Witty Pi 3!

Today we proudly announce our new product: Witty Pi 3, which is the direct descendant of Witty Pi 2, and has more exciting features.

Also, Witty Pi 3 supports the newly released Raspberry Pi 4!

 

 

What’s New?

Witty Pi 3 finally has its own brain: a micro controller (ATtiny841). Thanks to this micro controller, Witty Pi 3 behave much smarter and can detect and process much more complex situation. The firmware for ATtiny84 is developed with Arduino IDE, and is open-source (will be available on GitHub soon). If you don’t mind losing warranty, it is possible to modify Witty Pi 3’s firmware and change its behavior as you wish.

Witty Pi 3 also added an LDO voltage regulator (LM29150) on board, which allows you to power Witty Pi with higher voltage. Now you can directly use 6V or 7.4V battery to power Witty Pi 3 + Raspberry Pi. The 5V micro USB connector is still there, and you can power Witty Pi 3 directly with 5v too.

Besides all those that can be done with Witty Pi 2,  Witty Pi 3 also monitor the input voltage and output current. You can tell Witty Pi 3 to gracefully shutdown your Raspberry Pi when input voltage is lower than certain value; you can also let Witty Pi 3 to wake up your Raspberry Pi when input voltage increase to certain value. All these setting can be done via I2C interface, and Witty Pi 3’s software already takes care of the hard work. You can make a lot of configurations via the software. The software installation is as simple as before, just run two commands:

Price and Where to Buy?

Witty Pi 3’s retail price is 530 CZK (about 20.82EUR  /  18.66GBP  /  23.57USD).

You can buy it directly from our e-shop or you may be able to buy it from our resellers soon.

Can I still get Witty Pi 2?

Yes, but it will be less convenient. Witty Pi 2 is now officially retired and will only be produced on request. We suggest all new customers to choose Witty Pi 3, which has more features and can do anything that Witty Pi 2 can do. I your product is using Witty Pi 2 already, and you don’t want to switch to Witty Pi 3, you can request us to produce some Witty Pi 2 boards for your project.

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.

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:

Now it is possible to put this USB hub with Raspberry Pi together into an Acrylic case:

If you also have Witty Pi on hand, this Acrylic case may be perfect for you 🙂

We just launched the “Smart Case” project

Our 7-Port USB Hub has the same PCB size than Raspberry Pi, so it can be easily mounted over or under the Pi. If you have a case for Raspberry Pi that can have its top cover removed, you can put the hub and the Pi together into the case:

Hub_In_CaseIt can help in some cases, but the hub is not well protected yet. Many customers suggested us to design a suitable case to hold both the Pi and the hub, so we launched this project.

This project includes some children projects, as we are actually designing different types of cases. The first sub-project that could be demonstrated is this one, which opens its design and is free for download and print with 3D printer.

There are other sibling projects on going and you will see the news very soon.

7-port USB hub for Raspberry Pi is temporarily sold out

The first batch of 7-port USB hub for Raspberry Pi has been sold out after 25 days since its official launch on 26th March. The stock is exhausted much faster than our estimation and our second batch is still under producing, so we have to mark the product “out of stock” for now. We are sorry for the break, and we will try our best to replenish our stock as soon as possible.

package_contentCustomers who have already placed their orders on our website will not get affected, and their hubs will be shipped as expected.
