A complete Arduino microcontroller development system on one chip
With the SAMD21G, a complete Arduino microcontroller development system with very less additional components can be build:
Note that we need a SAMD21G with a preprogrammed bootloader, but these are hard to get. I have a special programmer to burn the bootloader into SAMD21G chips:
You can also use the SAMD21G with bootloader to repair a blown up SAMD21 mini breakout board:
FOR SALE: ATSAMD21G18A-AU with Arduino Zero Bootloader
There is just one SAMD21 bootloader, it can be used for the Arduino Zero, SAM 15x15 and all other Arduino SAMD21 boards. If you don't want to burn the bootloader yourself, I can deliver an ATSAMD21G18 with bootloader to you.
To order, use the shop.
NEW: Mini SAMD21 development board 15x15mm (Arduino compatible)
The SAM 15x15 is an Arduino development board of just 15 x 15mm, with the same powerful controller as the Arduino Zero: the SAMD21G18. Despite the small size, it has more I/O pins than the Arduino Zero: 34 instead of 20. See the article and how to buy here.
