toothache

LED driver board based on PT4121 chip

Overview

The lamp beads are CREE’s XHP50.2

The circuit board is an aluminum substrate that was sampled for free at Jialichuang

Lighting effect

After the board was ready, it was simply tested, and the input voltage was 13V.

After only lighting it up for a while, the board felt a little hot.
