I have a bunch of C3-mini boards and it would be great to finally use them for something more interesting than a temperature sensor.
The next problem with this project is the used radio: The SX12xx series from Semtech is good but lacks a lot of features like the CC1101 as used in the Flipper Zero.
I really like the idea of using an ESP32 but the choice of the used radio is a bit akward.
I haven't looked closely at the files, but I wonder if there is anything stopping us from using the new C3 riscv version instead if S3.
C3 seems to be cheaper and more stable, but maybe the performance is a bit lower?
I have not tried yet, so cannot vouche for the quality.
BTW their factory firmware isn't complete, it's just for testing purpose.
