Gerber files can be found in the releases section, but you can also just create them yourself using KiCAD 6
To build one of these you will need:
-
1x ESP32 Devkit.
There are multiple revisions of this. make sure to get the 30-Pin one where the first pin on the left of the USB connector is labelled VIN.
-
4x 10k Resistor
-
4x 4-Pin PC Fan Header
I used the Molex 47053-1000
-
1x DC Jack
The board was designed with the CUI PJ-202BH in mind
-
1x 1N5817 Schottky Diode
To protect your voltage regulator
-
1x Voltage Regulator 12v -> 5v
I've used the RECOM R-785.0-1.0, which is very efficient and doesn't require any other components
-
0-2x 10uF 16v or similar cap
Your voltage regulator might need those
Soldering should be straightforward and easy even for beginners.
I recommend the following order:
- Resistors
- Schottky
- ESP32 Devkit
- (Caps)
- Fan Headers
- DC Jack
- Voltage Regulator
