arduino ZERO M0 compatible keychain AtSamD21E18

It is Winxi predecessor, but maybe interesting for someone ... It have real wings :) .... like Always wings :D

Similar projects worth following
Native 3.3V, many sensors, modules and SD cards are working on this voltage level
I want small board => more fun without shields => integrate some basic components on board
user button
user led
micro SD Card reader (not supported in arduino IDE now)
I think really nice shape :)
micro shields (coming soon > touch, encoder, 7 segment ...)


Atsamd21E18 (TQFP32 > same size as atmega328), more soldering fiendly than Atsamd21G18 (LQFP48)
no EDBG chip, programming via native usb only
256kb flash
micro SD card reader


Edge header: GND, 3.3V,SDA,SCL,RESET, RX,TX,PA04,PA03,PA02(10bit DAC)
Left wing: GND, 3.3V, PA08, PA09, PA14
Right wing: PA28 (Usb host ID), GND, JTAG (reset, gnd, 3.3v, swc,swd)
Powered from usb, it is great, you can use any your phone charger, powerbank etc...
No jtag programmer required, board have integrated USB bootloader

vote what is better Winxi or this ???

Enjoy this project?
