## Description

The Adafruit ATtiny1616 Breakout with seesaw is a versatile development board that combines an ATtiny1616 microcontroller with the Adafruit seesaw I2C framework and STEMMA QT connectivity. It works as both a standalone dev board and an I2C peripheral that adds GPIO, ADC, PWM, and NeoPixel support to any I2C-capable host. Pre-programmed with seesaw firmware, this board acts as an I2C-controlled co-processor — handling timing-sensitive tasks that many microcontrollers and single-board computers struggle with. It can also be reprogrammed as a general-purpose ATtiny1616 development board using the megaTinyCore Arduino core. Key Features ATtiny1616 Microcontroller – 16KB flash, 2KB RAM, 256 bytes EEPROM, internal oscillator up to 20 MHz, hardware multiplier Seesaw I2C Framework – Universal converter providing GPIO, ADC, PWM, and NeoPixel control over I2C 12× GPIO – Pins 0–5, 6, 8, 11, 14, 15, 16 with selectable pullup resistors 9× 10-bit ADC Inputs – Pins 0, 1, 2, 3, 4, 5, 14, 15, 16 5× 8-bit PWM Outputs – Pins 0, 1, 7, 11, 16 NeoPixel Output – Drive up to 250 NeoPixel LEDs from a single pin 127-byte EEPROM – Non-volatile memory for tokens or MAC addresses (last byte used for I2C address) Interrupt Output – Pin 6, triggered by any configured peripheral 2× I2C Address Selection Pins – Pins 12 and 13 for running multiple boards on one bus 2× STEMMA QT / Qwiic Connectors – Plug-and-play I2C with 10K pullup resistors 3.3V Regulator – Runs at Vin by default (up to 5V); solder jumper to select 3.3V logic 2V to 5V Operation – Wide voltage range for flexible integration Power and Activity LEDs – Green power LED, red indicator LED on pin 10 Also Available ATSAMD09 Seesaw Breakout – Original seesaw breakout with ARM Cortex-M0+ (requires J-Link for reprogramming) ATtiny816 Seesaw Breakout with STEMMA QT – Lower-cost variant with 8KB flash, 512B RAM, up to 60 NeoPixels Ideal For Adding extra I/O to Raspberry Pi, ESP32, or Arduino projects via I2C NeoPixel control from I2C-only platforms ATtiny1616 development and prototyping Seesaw firmware customisation and testing Package Contents 1× Adafruit ATtiny1616 Breakout with seesaw 1× Header strip set Note: This board does not include a bootloader. To reprogramme or customise the seesaw firmware, you will need a UPDI programmer (which can be made from a USB-to-serial cable and a single 4.7K or 10K resistor). The firmware is compiled using megaTinyCore. No support is provided for custom seesaw builds.

**Product Type:** physical
