Luminea ZX-2844-*

also known as:

  • XS-RGBW-LedControl-V2.0.2
  • JCD XS-RGBW

sold by PEARL and amazon (i know know if they are available outside D-A-CH)

Hardware

There is a ESP8266EX sitting on the backside. 4 PWM outputs are connected to drive the 4 output channels (RGB + W). Red is on GPIO14 Green is on GPIO12 Blue is on GPIO5 White is on GPIO13

The pushbutton is GPIO13. Assign it to Button1 for local on/off control.

You can configure it as a "generic module"

And set the GPIO as follow:

Function ESP8266 Pin Channel
R GPIO 14 PWM1
G GPIO 12 PWM2
B GPIO 5 PWM3
W GPIO 0 PWM4
PushButton GPIO 13 Button1

There is an second version with a green PCB and different pinout:

Function ESP8266 Pin Channel
R GPIO 4 PWM1
G GPIO 12 PWM2
B GPIO 14 PWM3
W GPIO 5 PWM4
PushButton GPIO 0 Button1

Serial Connection

See the Hardware Preparation page for general instructions.

The serial header (3.3V, RXD, TXD, GND) as well as GPIO0, GPIO2 and RESET (IO0, IO2, RST) are populated as test pads on the frontside of the PCB. You can easily add some solder to fix the wires during the flash process.

To place the board into flashing mode, you will need to short IO0 to GND. This can remain shorted while flashing is in progress, but you will need to remove the short in order to boot the Tasmota firmware.
