Description

The PCB provides the Auto-Program-Feature from the well known ESP-DevKit C and adds it to the cheap available Programmers. It provides a reset button and switches to configure the use of an ESP32 or ESP8266 Module (which require a slightly differing configuration of the GPIO pins) in manual or automatic mode. It is fully compatible with the usual ESP-Idf and ESP-Arduino Programmer Software.
Note: It is a spin-off from the ESP32-01 module.

Details

Note: The shown photos in the gallery show the first revision of the PCB where the PCB-Side was wrong fro the USB Connector. This has been fixed in the Gerber files and schematic shown here.
