Description
Description
**ESP32 board with 4 channel MOS-FETs for driving LEDs with PWM.**
- 5V supply to ESP32 module can be separated from 12V to MOS-FETs by not using the DC-DC Buck converter.
- Includes prototyping area.
- Only through-hole (THT) components used.
This is the ESP32 module I have used. It has an external antenna:
