Frequently asked questions
Can I use Arduino UNO shields with this board?
The header layout is similar, but the board runs at 3.3 V logic and its pin mapping differs from the UNO. Confirm each shield is 3.3 V compatible and check the pin assignments before stacking it.
Which board should I select in the Arduino IDE?
Install the ESP32 board package and select WEMOS D1 R32 or ESP32 Dev Module. Connect over USB and choose the correct port before uploading.
