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-AUT with Arduino Zero Bootloader
If you don't want to burn the bootloader yourself, I can deliver an ATSAMD21G18 with bootloader to you.
To order, contact me personally. You can pay with PayPal. The price is €7.50 and the shipping costs are €4.95 for all countries worldwide. You will also support my website financially this way.
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.
