ESP32 R4ge Pro
Back in January, I did a workshop at CodeMash 2020 on soldering and programming an ESP32-based conference badge. It went very well, with near perfect success among the 50 or so participants. The hardware was simple to assemble, but somewhat limited in terms of peripheral capabilities – especially in regards to audio output.
In the spirit of continuous improvement, I have prototyped the next generation of the badge, dubbed the “ESP32 R4ge Pro”. Enhancements include:
- CD-quality audio
- Stereo speakers with volume control
- MEMS microphone
- A bigger and touch-sensitive screen
- Firmware-controlled screen dimming
- Twin analog joysticks
- Integrated battery charging
A number apps and games have already been created for the R4ge Pro in the GitHub repo, with more planned and in development. These include:
- Pong clone
- Drum sequencer
- Internet radio player
- Wave recorder and FFT frequency analyzer
- FM Synthesizer
- Bluetooth tank/robot remote control
GitHub repo documents folder also contains full schematic, bill of materials, and a simple case STL file.

i think its good project, good documentation. try write to salesrep pcbway, ask free charge ask sponsorship.. goodluck ..
Dude fvcking what is this? "The shipping charges are expensive to ship the product you designed completely for free and gave to the community, give me money"? Really? In what world should the person who's already done a TON of free labor for you take money out of their own pocket and give it to you? UNREAL. Honestly, if I had stumbled across this comment and you were asking if the creator knew of any ways to reduce the shipping cost, or if it might be available in your country already in a store, or really ANYTHING ELSE I probably would have just offered to buy you one because I know damn well how much it sucks to be limited not by your creativity or skills but money. But this level of entitle_ment is so infuriating I honestly kind of hope you never get one of these.
