From the project
ESPHome RGBCCT LED Controller is a PCB design that support a 5-Channel LED arrangement with Red, Green, Blue, Warm White and Cool White LEDs.
The PCB is designed in KiCad. Fabrication and is tuned toward JCLPCB. I using my Whizoo Controleo3 oven to handle all but the Thru-Hole stuff which is hand soldered.
Rev A**: Has been fabricated, assembled, tested and is use in four places. There is one issue TMP1075 (U1) is connected to VINP and will burn when powered by 24V and must be left off the PCB.
Only the 5A configuration has been tested. Short circuit on LED outputs will not damage the board but the red LED will not light up. This type of short circuits will recover automatically recover when removed. Short circuits on the fan…
