ESP32 칩을 탑재한 에어리프트 WiFi 피더윙 보드
(Adafruit AirLift FeatherWing – ESP32 WiFi Co-Processor)
개요
- 본 제품은 ESP32 칩을 탑재한 에어리프트 피더윙 보드입니다.
- Feather M4와 같은 피더보드와 사용하여 피더보드에 WiFi 기능을 추가하여 줄 수 있습니다.
- WiFi가 ESP32 칩에의해 처리되므로 별도의 소켓데이터 캐쉬나 SSL 라이블러리를 컴파일하거나 디버깅할 필요가 없습니다.
- 8Mhz SPI를 통해 소켓기반 명령을 보내서 WiFi 통신을 할 수 있습니다.
- 3V나 5V 아두이노 보드와 사용이 가능합니다.

We placed an ESP32 module on a FeatherWing with a separate 3.3V regulator, and a tri-state chip for MISO so you can share the SPI bus with other 'Wings. Comes fully assembled and tested, pre-programmed with ESP32 SPI WiFi co-processor firmware that you can use in CircuitPython to use this into WiFi co-processsor over SPI + 2 pins. We also toss in some headers so you can solder it in and plug into a doubler, but you can also pick up a set of stacking headers to stack above/below your Feather.
We've tested this with all our Feathers and it should work just fine with them except the ESP8266 & ESP32 Feathers (cause they already have WiFi!). For use in Arduino, the '328 and '32u4 you can do basic connectivity and data transfer but they do not have a lot of RAM so we don't recommend them - use the M0, M4 or similar, for best results! For CircuitPython use, a Feather M4 or nRF52840 works best - the M0 series does not have enough RAM in CircuitPython.
The firmware on board is a slight variant of the Arduino WiFiNINA core, which works great! At this time connection to Enterprise WiFi is not yet supported.
