## Description

The Adafruit ATSAMD09 Breakout with seesaw is a versatile I2C peripheral board built on the Adafruit seesaw framework. Seesaw is a near-universal converter that lets you add GPIO, ADC, PWM, and more to any I2C-capable microcontroller or single-board computer — all over a simple I2C connection. Rather than sourcing separate I2C GPIO expanders, ADCs, and PWM drivers, this single board provides a wide range of capabilities controlled through an easy-to-use library. It's ideal for adding extra hardware support to platforms like Raspberry Pi, ESP8266, or Arduino. Key Features Seesaw I2C Framework – Universal converter providing GPIO, ADC, PWM, and NeoPixel control over I2C 3× 12-bit ADC Inputs – High-resolution analogue-to-digital conversion 3× 8-bit PWM Outputs – For LED dimming, motor control, and other applications 7× GPIO – With selectable pullup or pulldown resistors NeoPixel Output – Drive up to 340 NeoPixel LEDs from a single pin 64-byte EEPROM – Non-volatile memory for storing access tokens or MAC addresses Interrupt Output – Trigger from any of the configured peripherals 2× I2C Address Selection Pins – Run multiple boards on the same bus Activity LED – Visual feedback for board status Reprogrammable – Customise the firmware to adjust peripheral allocation (requires J-Link programmer and SWD adapter) Also Available ATtiny1616 Seesaw Breakout with STEMMA QT – More GPIO/ADC/PWM, 16KB flash, STEMMA QT connectors ATtiny816 Seesaw Breakout with STEMMA QT – Compact alternative with STEMMA QT connectors Ideal For Adding extra I/O to Raspberry Pi, ESP8266, or Arduino projects NeoPixel control from I2C-only platforms Rapid prototyping with configurable peripherals Seesaw firmware development and testing Package Contents 1× Adafruit ATSAMD09 Breakout with seesaw 1× Header strip set Note: This board does not include a bootloader. To customise the seesaw firmware, you will need a J-Link programmer and an SWD adapter breakout. Custom firmware builds use Atmel Studio (or arm-gcc with a Makefile). No support is provided for custom seesaw builds.
