Wled is used as a firmware for controlling LED using Wi-Fi. You can find the source code of WLED MoonModules here. WLED is licensed under GNU General Public License v3.0. I don't provide the source code, because .bin is compiled from unmodified source code from the original repository with enabled Battery usermod. Your can get the compiled FW for ESP32 here (WLEDMM_0.14.0-b25.29_esp32_16MB_M.bin) or compile it yourself. All required information about configuring, compiling and tweaking can be found in Wled wiki.
