Feather board combining ATSAMD21 Cortex-M0 with an ATWINC1500 Wi-Fi module and u.FL antenna connector. Includes USB and LiPo charging. The uFL connector allows external antenna for improved range vs. the PCB-trace antenna variant.
One grouped connection is listed in the table but omitted from the graphic until individual pins are available.
| Pin | Position | Type |
|---|---|---|
| GPIO #0-#13, A0-A5, SCKMOSIMISO | logic pins | SPI, Signal |
USB · 3.3 V
Verify supply voltage and logic levels before powering up.
Module pins: GND / BAT / USB / EN / 3V / RST / ARef, GPIO #0-#13, A0-A5, SCK/MOSI/MISO, ATWINC1500 specific (CS, IRQ, RST, uFL antenna). Schematik maps them to your board in the app.
Specialists: Teensy for high-clock audio and USB, Adafruit SAMD boards running CircuitPython or the Arduino IDE, proper STM32 eval kits, and the micro:bit classroom ecosystem. Schematik builds target ESP32, Arduino Uno, and Pico; come here when you have a specific reason to.
