UV LED MOSFET driver board for custom PCB light etching

This is a a MOSFET driver board that can source 4x 1A of current to 4 separate arrays of ultraviolet LEDs. The purpose of this project is to design a UV exposure box that can develop photoreactive printed circuit boards. I didn’t have a large bench power supply that can supply 4A of current to […]

DIY Circuit Board Exposure Box Using UV LED’s

Exposure board almost done. Intend on using along side an Arduino Nano to be used as a timer and to control light intensity. In the end will have an additional light board for exposing 2 layer PCB’s source
