What is it?

This is an ATtiny 3217-based, breadboard friendly development board in a similar format to the Arduino Pro Mini / Pro Micro. What sets this board apart is that the UPDI programmer is built in.

There is a switch on the board that lets you choose between programming and running your code - basically, it switches the USB->UART RX and TX pin between the UART pins on the ATtiny and the UPDI pin for programming.

It also has a STEMMA QT / QWIIC jack for use with many of Adafruit's and Sparkfun's sensor modules. Or, it can use used as an I2C/TWI sensor in peripheral mode.

Why did you make it?

I use the newer ATtiny chips a lot as I2C/TWI peripherals, and I wanted a more convenient way to develop using these chips.

How can I use it?

These newer ATtiny chips are surprisingly easy to use thanks to the work of Dr. Azzy AKA Spence Konde. They can be easily programmed using most versions of the Arduino IDE or PlatformIO/VSCode.
