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: [ESP32-T WiFi Entwicklungskit Development Board ESP32-Bit Wireless Module ESP-32](https://www.ebay.com/itm/ESP32-T-WiFi-Entwicklungskit-Development-Board-ESP32-Bit-Wireless-Module-ESP-32/272598697050?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649)
