ESP32 Module Schematics and Board Files

Espressif teased about their ESP32 WiSoC with WiFi and Bluetooth LE a few weeks ago in a letter addressed to developers, but did not release that much information. The company has now released some documents in the forums (registration required) concerning ESP32 module  including PCB processing requirement, schematics and PCB layout, and bill of materials.

The very first modules will actually be based on ESP31 processor, which only slightly differs from ESP32 with some swapped pins. The BoM is pretty small with several capacitors and resistors, one inductance, a 26 MHz crystal, ESP31, and a Gigadevice flash.


The schematics have been designed with Orcad 16.6, so if you don’t have the program, you can read the schematics with Orcad 16.6 Lite, which is free to download. I’ve also printed the schematics to a PDF file.  I’m not sure how to open the .pcb file which should be the module’s PCB layout.
