Adafruit have today announced a new addition to their range of electronic breakout boards with the launch of the Adafruit ATSAMD09 Breakout offering support for seesaw a near-universal converter framework. The addition od Seesaw allows makers, developers and hobbyists to add and extend hardware support to any I2C-capable microcontroller or microcomputer. Rather than getting separate I2C GPIO expanders, ADCs, PWM drivers and more.
Specifications of the Adafruit ATSAMD09 Breakout board include :
• 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 340 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
Adafruit explains more about the new retail development board they have created.
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. 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.
