RGB led lighting module update

Posted on by

Hello
This is an update for the led lighting project.
The design in complete and the PCB’s are almost ready.
This is the schematic:

There are some things that can be added – status LED’s, temperature / voltage / current sensors, etc. but i’ll use this version as the prototype board. The MCU has 6 ADC’s and several IO pins available for these features.
The PCB dimensions are 50x50mm , 1mm thick 35um copper, double layer.
To reduce the cost I skipped the solder mask and silk screen.
The PCB is HAL coated – to increase solder adhesion and protect the copper.
I’ve also ordered free SMT stencils to try out working with PB-free solder paste and the hot-air gun.

This is the PCB, created by PCB POOL
