Flash GLEDOPTO GL-C-310WL

I was recently working on a project that needed an ESP32 powered from a 12 volt source with 4 GPIO PINs, ready-made, and in a case. I started going down the custom built route when I ran across the GLEDOPTO GL-C-310WL for a good price and picked one up to see if it could be re-flashed. The 310WL differs from the 309WL in that the 310L has a built-in I2S microphone, which may be useful for some projects like OpenAI integration, but that’s a future project.
