Product description: ATtiny816 Breakout - extension for Arduino - with connectors - STEMMA QT / Qwiic - Adafruit 5681
ATtiny816 Breakout is a module manufactured by Adafruit that acts as a pin expander . It is designed to be used with boards that use the I2C bus , such as Arduino and Raspberry Pi. It extends the functionality of these boards with an additional 12x GPIO, 9x ADC, 5x PWM, 1x NeoPixel, 1x EEPROM with 127 bytes of NVM memory (the last byte of the EEPROM is used to select the I2C address) and 1x interrupt pin. The module is equipped with the ATtiny816 microcontroller with 8 kB of Flash memory, 512 bytes of RAM and 128 bytes of EEPROM memory.
