Kitchen Leds

Zigbee ESP32 LED Dimmer

Small project designed to implement ESP32, Mosfets and Zigbeee as seen on my YouTube video https://youtu.be/TzyIVoRmAFQ

PCB

Select a PTC fuse for your needs, upto 5A, board is rated for up to 24VDC.

You should match the power supply voltage with the voltage of your LEDs, there is an onboard buck converter for powering the ESP32.

CH1 and CH2 are available for controlling two single colour zones.

CH1 and CH2 can be combined with CH3 and CH4 to control a single RGBW header, or you can use just CH2, CH3 and CH4 to control a RGB header.

Barrel jack is centre positive.

Arduino IDE Settings

Some settings neet to be configured in Arduino IDE:

Under tools:

• USB CDC On Boot : "Enabled"
• Partition Scheme: "Zigbee ZCZR 4MB with spiffs"
• Zigbee Mode: "Zigbee ZCZR (coordinator/router)"

3D Printing

If you are going to use the included enclosure, you will probably need to trim the header pins of the ESP32C6 module to make it fit.

Screws are M3, threaded inserts are: M3*4.6x5.7mm

⚠️ Warning

Some of the ESP32C6 minis that I purchased (specifically the blue ones), seem to not have a working GPIO5, instead GPIO5 toggles GPIO23 in the code. And interestingly GPIO 23 also controls GPIO 23 but testing with a DMM shows that GPIO 5 and 23 are not shorted. I have no explanation, so you may have to run a jumper wire to a different GPIO unless you can find a solution.

The Purple ESP32C6 that I initially used, did not have this problem.
