Adafruit ATSAMD09 Breakout

Adafruit ATSAMD09 Breakout Board with Seesaw

ATSAMD09D14 SAM D ARM® Cortex®-M0+ MCU 32-Bit Embedded Evaluation Board

DESCRIPTION

     Adafruit ATSAMD09 Breakout Board with Seesaw is a near-universal converter framework and is great for the development of seesaw capabilities. This breakout board allows the user to add or add and extend hardware support to any I2C-capable microcontroller or microcomputer. The ATSAMD09 breakout board can be configured to give a wide range of capabilities including I2C GPIO expanders, ADCs, and PWM drivers without extra expenditures. This breakout board features 3 x 12-bit ADC inputs, 3 x 8-bit PWM outputs, and 7 x GPIO with selectable pull-up or pulldown. The ATSAMD09 breakout board also offers 1 x NeoPixel output, 1 x EEPROM with 64bytes of NVM memory, and 2 x I2C address selection pins.

     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.

SPECIFICATIONS

• Powered by Microchip's ATSAMD09 ARM®-Cortex®-M0+ MCU
• Near-universal converter framework
• Add and extend hardware support to any I2C-capable microcontroller or microcomputer
• I2C GPIO expanders, ADCs, and PWM drivers etc
• Great for the development of seesaw capabilities
• Can be used as-is to give the Raspberry Pi or ESP8266 more hardware support
• Compact and economical
• 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!
