Troubleshooting
If you’re having trouble uploading code to either of the ESP32 boards, ensure that the CH340C driver is installed correctly by following the instructions outlined in Step One of this tutorial. You should also ensure that “Sparkfun ESP32 Thing Plus C” is the selected board. You can confirm this by clicking on the “Tools” tab at the top of the Arduino IDE and then looking to see what the “Board” is listed as. Note that there are multiple boards with names that are similar to “Sparkfun ESP32 Thing Plus C”. Take care to choose the correct board.
