This Wio board is a cost-effective Arduino compatible board with the W600 WiFi module. The board features Atmel SMART SAM D21 ARM Cortex-M0+ based microcontroller and the W600 WiFi core is a 2.4GHz WiFi module features ARM Cortex-M3. Since the Wio Lite W600 uses SAM D21(the same chip used in Arduino Zero) as its Arduino Core, in theory, it is fully compatible with Arduino zero.
We’ve broken out the SAM D21 pins, the I/O level of this board is 3.3V. There are 6 analog pins and 14 digital pins, and also one UART, one I2C, one ICSP port is available. You can power this board with 5V USB Type C and 3.5V~4.2V Lipo battery.
