After only a few hours of work, I’ve completed the circuit and it looks great! The big blue thing is the standard ESP-12 module. To the left is the programming connector. Below the blue part is the 3.3V power regulator. All around the board are 3-pin connectors that are compatible with servos. The connectors are all GPIOs except the A0 connection which is only for the internal ADC.
Up next, I’ll order the boards and all the components. I intend to order the PCB through OSHPark, the ESP-12 module from Ebay, and the rest of the components from Mouser (at least the ones I don’t already have).
For anyone wanting to look at this board in CircuitMaker, I believe you can search ESP IOT Breakout and it should come up. Let me know if that doesn’t work in the comments or by using the contact page. I’ll put up a parts list soon!
