DuinoTech SAMD21 Main Board with Built-in Wi-Fi – Arduino Zero & Feather Compatible | XC3812

You've got a project that needs Wi-Fi but not the footprint of a full dev board. This is it. DuinoTech's SAMD21 board packs a W600 2.4GHz Wi-Fi module (802.11 b/g/n) into a small form factor built for low-power IoT work. Six analogue pins, fourteen digital, UART, I2C, ICSP – all the usual suspects, present and accounted for. USB Type-C handles power and programming. Want it portable? There's a provision for a 3.5–4.2V Li-Po battery (sold separately). It speaks Arduino Zero and Adafruit Feather, so your existing code just runs. Grab one and stop fighting with external Wi-Fi shields
