For example, there's also a UART converter but it isn't included in the default firmware.\u003c\/p\u003e\n\u003cp\u003eThe ATSAMD09 breakout is great for development of seesaw capabilities (Adafruit use it in-house for their 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note: \u003c\/strong\u003eThe boards do not come with a bootloader. If you want to do development on seesaw (e.g. changing the configuration) \u003ca href=\"\/en-eu\/search?type=product\u0026amp;q=j-link\" target=\"_blank\"\u003eyou'll need to pick up a J-Link\u003c\/a\u003e. At this time Adafruit's project is for Atmel Studio but you could probably get it working with arm gcc and a Makefile. They don't provide any support for custom builds of seesaw - they think this is cool and useful for the Maker community!\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/adafruit-seesaw-atsamd09-breakout\/\" target=\"_blank\"\u003eFor more details including the documentation on how to use seesaw, libraries for Arduino\/CircuitPython\/Raspberry Pi Python, schematics, and more check out the Adafruit seesaw guide\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTECHNICAL DETAILS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUses I2C address 0x49 - can be changed to 0x4A, 0x4B or 0x4C\u003c\/li\u003e\n\u003cli\u003eProduct Dimensions: 32.0mm x 12.0mm x 3.5mm \/ 1.3\" x 0.5\" x 0.1\"\u003c\/li\u003e\n\u003cli\u003eProduct Weight: 1.6g \/ 0.1oz\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":1130654629898,"sku":"ADA3657","price":5.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/3657-00_fa4f0831-27a8-4c5e-87a7-d9db0c51df80.jpg?v=1663340611","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/adafruit-atsamd09-breakout-with-seesaw","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
