ATtiny1616 Breakout - extension for Arduino - with connectors - STEMMA QT / Qwiic - Adafruit 5690

ATtiny1616 Breakout is a module manufactured by Adafruit, which 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 EEPROOM 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 ATtiny1616 microcontroller with 16 kB of Flash memory, 2 kB of RAM and 256 bytes of EEPROM.
