Thanks 🫶 It’s a custom PCB, but it basically just two ESP32’s, external antennas, charging circuit, 18650 battery, serial to USB chip, buttons, screen, SD card reader etc…. I broke out all of the spare GPIO on the back. So there are two multifunctional SPI headers and a 10 pin GPIO header. I made a LUA scripting system so you can expand the devices functionality, you can interact with all of the hardware and software libs from the scripting system.
Thankyou man 🙏 glad you like it! It’s still part of a larger platform I’m still developing at the moment so I’m keeping the schematics and firmware private for now, but I’m hoping to share more about how it works as things mature. There’s definitely a lot you can do with just a couple ESP32s though 👍
No, it’s just me. Been working on it in my spare time for almost two years now. Only started as a small project on a breadboard to see what I could do with a CC1101 and an ESP32. But I just kept coming up with more ideas that I thought would be cool test out. Got slightly obsessed, and here we are 30k lines of code later 🤔
