Adafruit Pro Trinket - 3V 12MHz
- A highly-capable Cortex M0+ processor with ton more I/O pins, lots of 12-bit ADCs, a 10-bit DAC, 6 total SERCOMs that can each do SPI, I2C or UART (3 are used by the existing interfaces, leaving you 3), plenty of timers, PWMs, DMA, native USB, and more.
- The ATWINC has much lower power usage, about 12mA for the WINC & 10mA for the ATSAMD21 with auto-power management on for the WiFi and no power management for the ARM..
- Stream more reliably (less 'bursty') with the ATWINC..
