The MQTT RGB LedPanel is made my tree main parts:

  • A RGB panel composed by 1024 RGB leds ordered in 32x32 grid on a black PCB of 19x19 cm size. This part usually is made by a Chinese company called LINSN
  • An Arietta G25 Linux module complete with a WiFi module
  • A 4A 5VDC wall adapter

All the parts can be fixed inside a cheap and elegant IKEA RIBBA photo frame as shown below:

Getting started

Insert the microSD provided with the MQTT LedPanel kit inside your PC. The first partition is formatted in FAT32 so you can access to it on any OS (Windows, Linux or OSX).

Edit the file wpa_supplicant.conf using and ASCII editor like Nodepad, Nodepad++, Wrangler, gedit, etc.

What is FAT32 ? What is an ASCII editor ? What is wpa_supplicant.conf ?

Insert the name of your WiFi access point and the password to get the access:

    ssid="your access point name"

    proto=WPA RSN
    pairwise=CCMP TKIP
    group=CCMP TKIP

then save it, unmount the microSD and use it to boot your LedPanel.

Turn-on the LedPanel and wait. After about 1 minute will appear the mac address on the RGB panel.
