ESP32 based board with 4 pixel string channels programmed with WLED for controlling 5V and 12V LEDs

ESP32 based board with 4 LED channels used for use with WLED software. This ESP32 board features, the powerful ESP-WROOM-32E module, with integrated WiFi and Bluetooth functionality (BR/EDR/BLE). The ESP32 is a chip designed with TSMC ultra-low power management technology. The proven ESP32-D0WD-V3 chip is located in the core of the developed module. This board has a USB-C interface for download of firmware and 5v power during development. The board is flashed with WLED for immediate control of up to four independent addressable LED strips. The board is compatible with WS2811(5/12v), WS2812(5v), WS2812B(5v), WS2813, WS2815(12v), SK6812(5/12v), USC1903(5/12v), TMS1812(12v), and others 3 pin styles. It also has headers that allow use with conventional WeMos D1 Mini style daughter boards and is therefore pin compatible with most accessories. This board has high current 5 volt drivers for driving long LED control signals. It also has three, 3-pin screw connector for one-wire devices, each with 3.3v power and ground. Custom WLED Usermod available for use with two temperature controlled PWM fans and two LED strips (fans/strips must be same supply voltage).

Specifications:

Size: 84mm x 44mm with 2mm mounting holes.
Processor: ESP32 on ESP32-WROOM-E module with WiFi and BT V4.2.
Power Input: 5-15v @ 10 amps max via 5.5mm x 2.5/2.1mm barrel or 5v @ 3 amps via USB-C connector*.
On Board Regulation: 5v @2 amps switching regulator, 3.3v @800 milliamps.
LED Outputs: Four connectors each with 5v driven LED data output signals, 5/12V power (voltage is the input voltage on barrel connector), and ground.
I/O: USB 2.0 via USB-C connector using the CP2102N.
I/O: Standard WEMOS daughter interface on two 1x8 pin headers.
I/O: Dallas 1-Wire interface with 3.3V and ground on screw style terminals.
I/O: JST SH Connector for I2C/PDM interfaces.
The board comes with four KK style 4-pin to JST 3-pin extension cables.
Ten amp power input (for applications requiring more than 10 amps use external power injection to LED strips, for most use cases this is approximately 2000 LEDs).
A 3D printed enclosure is also available (+$5.00).
A power injection relay is available (+$3.00).
A I2S MEMS Microphone is available (+$6.00)

COMES PRE-FLASHED WITH THE LASTEST WLED AND CONFIGURED

The 5 volt LED power is not supplied from the USC-C connector. LED power must be injected or supplied via Barrel connector.

It works!

It's alive! https://i.imgur.com/xxmMIjO.jpeg

Setup was quick and easy using the WLED app on Android.

I'm dubious about the barrel connector being able to take the full 12 amps (e.g. Mouser's selection of barrel plug parts tops out at 8A ratings), so I'll be injecting power to the LED strips directly instead (I'll have 1,800 LEDs).

Response from ESP32andmore.com | April 7, 2024

Thank you for your review. Very cool matrix. Six times the size you show in your photo!! Please let us know what like for refresh rate you get with WLED with the 1800 LEDS. In regards to the current rating, the board's copper is rated at 12 amps given a 30C temp rise. Each of the KK-style connectors is rated at 7.5 amps (but if you actually measure the conductor and by calculation it can handle 16 amps). There are four. The fuse is rate at 12 amps. The barrel connector we use is rated at 8 amps but looking to the actual copper the ground conductors can handle 30+ amps and the center pin, 40+ amps (this is the IPC-2152 for short conductors). The limit with these connectors is the ground contact with the plug, difficult to calculate. Since I routinely see 10 amp power supplies with the same barrel connector (https://a.co/d/fc3LVsZ) and have seen 12 amp versions, we decided to test the connector and board. We ran the barrel connector under a 15amp load for an extended period and it was not damaged. We also tested the board loading 2 KK-style connectors through the barrel connector @ 12amps and tested fine.
I would use the 12 amp number as a rule of thumb to size the number of LEDS since rarely are you using 20ma per LED (3 channels full on) and that works out to be 600 LEDS. And I would similarly size your PS according as you never want to draw full amperage rate of a PS. And in your use case 1800 LEDS full on you are looking at 48 amps, so power injection is the only viable option given also any controller board. Your feedback was much appreciated and good luck with your COOL project!!
