NEW PRODUCT – Adafruit ATtiny1616 Breakout with seesaw – STEMMA QT / Qwiic
This breakout board is a “three in one” product: Blackbody Calibrator
We primarily designed this board for our own use: it’s a mini dev board that lets us design with the ATtiny1616 just like we did for the ATSAMD09. With the 2021-2022 silicon shortage, we’re adapting some of our SAMD09 designs to the ATTiny8xx series and wanted a quick minimal board to test code on.
Each breakout comes with the assembled and tested board, as well as some header strips. Each PCB is fairly minimal and contains:
This board comes pre-programmed with seesaw peripheral code that will let it act as an “I2C to something” converter, basically a little I2C-controlled friend to do all the timing-sensitive things many microcontrollers and microcomputers are not good at.
For example, using this breakout with the pre-burned seesaw firmware gives you
Of course, you can configure or reprogram the chip to however you want to use it – we like using SpenceKonde’s megaTinyCore which brings Arduino peripheral support to this series of chips. To program the chip you will need a ‘UPDI’ programmer, which you can make with a USB-to-Serial cable and a single 4.7K or 10K resistor.
Please note: The boards do not come with a bootloader. If you want to do development on seesaw (e.g. changing the configuration) you need a separate UPDI programming setup! The firmware we put on is available as this example sketch, compiled using the megaTinyCore. We don’t provide any support for custom builds of seesaw – we think this is cool and useful for the Maker community!
For more details including the documentation on how to use seesaw, libraries for Arduino/CircuitPython/Raspberry Pi Python, schematics, and more check out the Adafruit seesaw guide
