Adafruit seesaw is a near-universal converter framework which allows you to add and extend hardware support to any I2C-capable microcontroller or microcomputer. Instead of getting separate I2C GPIO expanders, ADCs, PWM drivers, etc, seesaw can be configured to give a wide range of capabilities.

For example, our ATSAMD09 breakout with seesaw gives you

  • 3 x 12-bit ADC inputs
  • 3 x 8-bit PWM outputs
  • 7 x GPIO with selectable pullup or pulldown
  • 1 x NeoPixel output (up to 63 pixels)
  • 1 x EEPROM with 64 byte of NVM memory (handy for storing small access tokens or MAC addresses)
  • 1 x Interrupt output that can be triggered by any of the accessories
  • 2 x I2C address selection pins
  • 1 x Activity LED

But you can reprogram and reconfigure the chip to have more or less of each peripheral - as long as it fits into the ATSAMD09D14's firmware! For example, there's also a UART converter but it isn't included in the default firmware.

The ATSAMD09 breakout is great for development of seesaw capabilities (we use it in-house for our design work) or you can use it as-is to give your Raspberry Pi or ESP8266 more hardware support! Each breakout comes with the assembled and tested board, as well as some header strips.

Please note: The boards do not come with a bootloader. If you want to do development on seesaw (e.g. changing the configuration) you'll need to pick up a J-Link and we recommend a SWD adapter breakout. At this time our project is for Atmel Studio but you could probably get it working with arm gcc and a Makefile. We don't provide any support for custom builds of seesaw - we think this is cool and useful for the Maker community!

Technical Details

  • Uses I2C address 0x49 - can be changed to 0x4A, 0x4B or 0x4C

Revision History:

  • As of Oct 6, 2020 we're shipping a verion with a firmware fix to support over 64 NeoPixels. Orders shipped before Sept 14, 2020 have a bug in the current shipping seesaw firmware that can only support up to 63 NeoPixels
