Based on newest arduino zero board with powerful mcu. Native 3.3V, many sensors, modules and SD cards are working on this voltage level.
I want small board : => fun without shields => I2C header => micro sd reader
= WINXI (because predecessor have small wings)
- User button - Power led - Optional micro SD Card reader (not supported in arduino IDE now) - RGB LED - Touch button pad (on bottom of board) - I2C header - Jtag header - Metallic Usb-A support - In next version vertical Usb for usb host - Minimum components - I think really nice shape :)
- Atsamd21E18 (TQFP32 > same size as atmega328), more soldering friendly than Atsamd21G18 (LQFP48) - No EDBG chip, programming via native usb only - 256kb flash - Smart pinout !!!! Direct IIC/ TWI sensors most used combination vcc/gnd/scl/sda
Powered from usb, it is great, you can use any your phone charger, powerbank etc... No jtag programmer required, board have integrated USB bootloader
