The firmware is currently compatible with the original ESP32, ESP32-C3, and the ESP32-S3. Generally C3 or S3 is recommended for new deployments. The C3 is nice and cheap and the RISC-V is fast! The S3 has better bluetooth range but is a bit more pricey.
It is not compatible with the ESP32-S2 (doesn’t have bluetooth), ESP32-C6 (too new no support in our dev environment), or ESP8266 (old, no bluetooth).
