User Manual

We placed an ESP32 module on a PCB with level shifting circuitry, a 3.3V regulator, and a tri-state chip for MOSI so you

can share the SPI bus with other devices. Comes fully assembled and tested, pre-programmed with ESP32 SPI WiFi co-

processor firmware that you can use in CircuitPython to use this into a WiFi co-processsor over SPI + 2

pins (https://adafru.it/Evl). We also toss in some header so you can solder it in and plug into a solderless breadboard.

The firmware on board is a slight variant of the Arduino WiFiNINA core, which works great! (https://adafru.it/E7O) At this

time connection to Enterprise WiFi is not yet supported.
