Esp32 LED Driver

An ESP32 LED Driver for use with ESPHome. Supports 12 volt and 24 volt LEDs.

NOTE:

This was a fun project I did for myself, where I added a few minor things I wanted, and maybe you will learn something from what I put together. However after I finished by baord, I found QuinLED, I recommend you go look at QuinLED-An-Deca over having my board manufactured.

Goals

• Work with 24 Volt LEDs, at least 1.5 amps
• Independed control of two RGB-W strips, or eight white LED Strips
• Work well with Home Assistant
• Built in power monitoring
• Price is $50 to $75 per board

Pin assignment on ESP32

• Test LED - ~IO19 (was ~IO13 in V1)
• SDA - IO21
• SCL - IO22
• INA219 - i2c address - 45
• CHAN 1 - IO32
• CHAN 2 - IO33
• CHAN 3 - IO25
• CHAN 4 - IO26
• CHAN 5 - IO27
• CHAN 6 - IO18
• CHAN 7 - IO17
• CHAN 8 - IO16

The result

Case

I have designed a case for it as well over on OnShape for use with a 3D printer.

Print uses M3 3D Printing Brass Nuts, 5mm x 6mm Embedment. Found them on Amazon here.

Other resources

• WLED Software that also runs on ESP32 and should work on this board using the Analog controls, if you don't have HA or don't use ESPHome.
• QuinLED-An-Deca Use this board over my board.
