ESP32Cam Programmer

Based on Insan Sains work I made my own version using almost all through-hall components (excluding the A04300) and adding an external power jack. I also simplified the design by using a CH340G pre-built module for USB to TTL data transfer between ESP32Cam and PC.

Here is the the list of components.

• S8050 transistor TO92 (2)

• A04300 (SMD SOT23)

• 10K resistor (4)

• Arduino female pins (double row)

• Arduino male pins angled (reverse bending)

• XH 2.54 2pin angled

• CH340G USB to serial module

• Push button angled 6x6

• Miniature slide switch DPDT switch

The push button is a Reset button. The XH connector is for 5V external power supply for the ESP32Cam (e.g. 2A or more USB universal mobile charger). To supply external power, set the micro-switch accordingly (left position, with respect to PCB image below).

Send me an email if you want the PCB's Gerber files.
