How would you recommend connecting 3. I would like to power my ESP32 DEV Module with a power source other than the USB port. Also don't accidentally cross ground on the VIN side with ground on the 3.3v side, you will blow your board when powered via USB. Lab Fritzing-parts/MH-ET LIVE ESP32 DEVKIT 38 pins.fzpz at master. The board labels on board are pretty accurate except you need to know that those analog pins are not labeled unless you look at the schematic.Īlso when you power the board with a 5v USB you get 5v power out of the VIN pin, I used this to power a 5v servo with no problems, even during extended stall draw was ok.

Just not the following, the GPIO pins follow the numbers 1-27 (lower right pin out schematics), but the analog pins labeled as A6-A9 are 34, 35, 32, 33, 25, 28. Here you go :) It also took me a while to find the schematics. I did this because this esp32 board doesn't fit on one breadboard (only has access to one side of pins), There is a gap between the two boards I though as the rails do not join across the two. Thanks for the advice! I thought I had the breadboard configured correctly by slapping two of them together. The vertical power rails (+,-) are continuous from top to bottom. The Horizontal columns are broken into 2 sections.

Your breadboards have horizontal and vertical busses. that will allow you to access the other 4 holes for each of the module pins. Is there a correct header file somewhere. Spread those breadboards apart so that the you have an air gap under the module. Arduino for ESP32 has variants/doitESP32devkitV1 has pinsarduino.h with symbold A0.A19 not matching the one and only doit board I have seen. The way you have the module inserted into the breadboards doesn't give you access to the signals from the module. You need to understand the configuration of your breadboards.

The silk screen naming of your board is what you would use.
