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:

wget http://www.uugear.com/repo/WittyPi3/install.sh
sudo sh install.sh

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.
