The schematics/programs for this led matrix don't seem to exist. Which is a shame cause I want to reprogram it to respond to sound and play my own custom animation. The company that sells it (link below) has their own app that works pretty well with it, but I'd like to make my own software.
Does anyone know a way I could figure how to connect this to an Arduino Uno? Or find a data sheet for the led? Or did the company that made it somehow make that impossible?
JT-2121-1632-16S-V1.0, is the code that I'm assuming refers to the kind of led it is.
I've also picked up a similar LED matrix (mine is v1.1 though) for my project hoping that it could be easily controlled. But what I've learned so far is that the PCB glued in with the battery seems to mainly handle the charging and WiFi connectivity. The actual memory and control of the matrix seem to happen on the LED matrix side with a HC89F0541 MCU and a bunch of other chips.
While trying to send commands to it I connected it to 5V and it displayed a "Battery Charging" symbol. I'm going to try and dig further to see if it's possible to control this with an Arduino. So far I've also found this page dedicated to a similar matrix: Asian Flexible LED matrix – Anders K Nelson
