Witty Pi 4 Package Content Change

Starting from the first generation of Witty Pi, a CR2032 Lithium battery (usually in IKEA brand) is included in Witty Pi’s package. This convention is changed now: Witty Pi (4) no longer come with a CR2032 battery, instead it comes with a 22AWG 30cm XH2.54 cable (the same as this one).

The reason for such a change, is the restrictions of Lithium battery from more and more carrier companies. Nowadays even a small Lithium battery like CR2032 in package can be considered “dangerous” and the whole package needs to be specially processed. Considering CR2032 battery is very easy to buy locally, we replace it with a 22AWG 30cm XH2.54 cable, which we believe is more useful to most of Witty Pi 4 users. You may use this cable to connect Witty Pi 4 to power supply up to 30V, and the DC/DC converter on Witty Pi 4 will provide 5V to power Raspberry Pi.

By the way, that CR2032 battery is also not necessary for Witty Pi 4 usage. In case of not putting any battery in the battery holder, the worse situation is the RTC loses the time when power supply is disconnected, and it can be fixed by synchronising the time with Internet again. If Witty Pi 4 connects to power supply all the time, which is suppose to be the case for normal usage, its RTC will not forget the time.

The unit price for Witty Pi 4 remain the same after such change. If you ordered Witty Pi 4 during the end of February, you may receive either the old or new package. Starting from March we are sure we only send out Witty Pi 4 with new package content.

 

New Product: Witty Pi 4 L3V7

Today we hereby announce the new member of Witty Pi 4 family: Witty Pi 4 L3V7. This is the first Witty Pi product that integrates the battery charging circuit and hence can be used directly as an uninterruptible power supply (UPS).

Witty Pi 4 L3V7 has the same shape factor as Witty Pi 4 Mini, but it includes more functionalities. The table below shows the comparison between Witty Pi 4, Witty Pi 4 Mini and Witty Pi 4 L3V7.

The diagram below demonstrate how Witty Pi 4 L3V7 will get connected.

Witty Pi 4 L3V7

After connecting a chargeable 3.7V Lithium ion/polymer battery to Witty Pi 4 L3V7, you can use it as an UPS.  If 5V power supply is connected, the device will be powered by USB power and the battery will also be charged. If the 5V power supply is off, the battery will immediately take the palace and power the device. When its voltage drops under the preset threshold, it will shut down your Raspberry Pi.

Witty Pi 4 L3V7

More information bout this new product can be found on its product page.

Witty Pi 4 L3V7 ’s retail price is 23.00 EUR (about 19.58GBP  /  23.54USD  /  30.34CAD), and you can order it here.

You may be able to order them from our distributors soon.

 

New Product: Witty Pi 4 Mini

After we announced Witty Pi 4, there is no surprise that Witty Pi 4 Mini is also on its way. Today is the day, and we now announce our new product Witty Pi 4 Mini.

Witty Pi 4 Mini has same shape factor as Witty Pi 3 Mini, and the connector locations are not changed. This make Witty Pi 4 Mini and Witty Pi 3 Mini physically exchangeable.

What’s New?

Comparing to Witty Pi 3 Mini, Witty Pi 4 Mini uses USB type-C connector instead of micro USB connector, and it has another unpopulated 7-pin header in the middle of the board.

Comparing to the full-sized Witty Pi 4, Witty Pi 4 Mini uses super capacitor instead of CR2032 battery for off-power time keeping. Witty Pi 4 Mini doesn’t come with an on-board DC/DC converter.

Similar to the full-sized Witty Pi 4, Witty Pi 4 Mini also uses the “single I2C device” design. Instead of exposing the realtime clock and temperature sensor directly to Raspberry Pi, it uses micro-controller (MCU) to emulate one I2C device (with address 0x08), and only exposes this I2C device to Raspberry Pi. On the other hand, it implement its internal I2C bus to communicate with the realtime clock and temperature sensor.

 

Witty Pi 4 Mini’s firmware is basically the same with the one in Witty Pi 4 Mini, except that it has a different firmware ID. Just like Witty Pi 4, Witty Pi 4 Mini’s firmware also maps all I2C registers in realtime clock and temperature sensor into its own I2C device, and you can access all I2C registers in realtime clock and temperature sensor via single I2C device.

Since the address of the single I2C device is configurable, you can always avoid the I2C address conflicting.

Same as full-sized Witty Pi 4, Witty Pi 4 Mini can also turn your Raspberry Pi into a temperature controlled device. You can put it into sleep when temperature is rather high, or the other way around.

Migrate from Witty Pi 3 Mini to Witty Pi 4 Mini

If you are using Witty Pi 3 Mini in your project, you may want to know more details about the the difference between Witty Pi 3 Mini and Witty Pi 4 Mini.  In the user manual, you can find a chapter (chapter 13) about how to migrate from Witty Pi 3 Mini to Witty Pi 4 Mini.

How about Witty Pi 3 Mini?

Witty Pi 3 Mini is discontinued. We unfortunately do not offer the possibility to continue producing Witty Pi 3 Mini, due to the shortage of DS3231SN chip.

We will do our best to help our customers to migrate from Witty Pi 3 Mini to Witty Pi 4 Mini.

Price and Where to Buy?

Witty Pi 4 Mini ’s retail price is 18.00 EUR (about 15.32GBP  /  18.42USD  /  23.74CAD), and you can order it here.

You may be able to order them from our distributors soon.

 

New Product: Witty Pi 4

Today we are very proud to announce our new product: Witty Pi 4!

This is the 4th generation of Witty Pi. Comparing with Witty Pi 3, it has same shape factor and same connector locations, and have some interesting new features.

Witty Pi 4

What’s New?

Witty Pi 4 uses a new structure to organise its hardware resources. Instead of exposing the realtime clock and temperature sensor directly to Raspberry Pi, it uses micro-controller (MCU) to emulate one I2C device (with address 0x08), and only exposes this I2C device to Raspberry Pi. On the other hand, it implement its internal I2C bus and connect the realtime clock and temperature sensor to that internal I2C bus.

Witty Pi’s firmware also maps all I2C registers in realtime clock and temperature sensor into its own I2C device, so you can access all I2C registers in realtime clock and temperature sensor via single I2C device.

Because the address of this single I2C device is also configurable, you can always avoid the I2C address conflicting.

A new feature of Witty Pi 4 is to turn your Raspberry Pi into a temperature controlled device. You can put it into sleep when temperature is rather high, or the other way around.

In Witty Pi 3, you cannot specify the “seconds” in scheduled shutdown time, and that was due to the limitation from the realtime clock hardware. In Witty Pi 4, the alarms for startup and shutdown are implemented by the firmware, and hence you can specify the “seconds” in both scheduled times.

There are other differences between Witty Pi 3 and 4, and you can find a chapter about how to migrate from Witty Pi 3 to Witty Pi 4 in the user manual (chapter 13).

How about Witty Pi 3?

Witty Pi 3 is discontinued. We understand it is not good for ongoing projects who use Witty Pi 3, and we wanted to continue producing Witty Pi 3 for a while. Unfortunately due to the shortage of DS3231SN chip, we can not do so and have to discontinue Witty Pi 3.

We will do our best to help our customers to migrate from Witty Pi 3 to Witty Pi 4.

Price and Where to Buy?

Witty Pi 4’s retail price is 25.00 EUR (about 21.48GBP / 29.80USD / 36.77CAD), and you can order it here.

You may be able to order them from our distributors soon.

New Product: MEGA4 – USB 3.1 PPPS Hub for Raspberry Pi 4!

Dear visitors, today we are proudly announcing a brand new product: MEGA4! This is a USB 3.1 hub designed for Raspberry Pi 4B, and it supports PPPS (per-port power switching)! It adds 4 more USB 3.1 ports to your Raspberry Pi 4B, and the power on each port can be turned ON or OFF separately via software.

MEGA4

MEGA4 is also fully supported by UWI (UUGear Web Interface), so you can use your web browser to monitor and control your MEGA4 device(s).

MEGA4 @ UWI

MEGA4 on the Phone

 

The advantage of being able to control power for each port is that you can turn OFF specify USB device(s) when they are not needed, to save energy. Also it is possible to fully reset a USB device by doing a full power cycle when it doesn’t function well after a long run. All these turning OFF/ON operations can be done remotely (either via SSH section or via UWI).

MEGA4 has the same board size with Raspberry Pi 4B and can be mounted underneath. It can also be daisy-chained like other USB hubs. The picture below shows an example to stack 3 MEGA4 devices together and that Raspberry Pi 4B eventually has 11 USB 3.1 ports.

You can find more information about MEGA4 on MEGA4 product page, or in MEGA4 user manual.

Price and Where to Buy?

MEGA4’s retail price is 28.00 EUR (about 24.06GBP / 33.38USD / 41.19CAD).
