Hi! I am actually directly involved with Pocuter. Amazing to see it posted here! The ESP32 alone doesn't have enough pins to handle all of the features of the Pocuter, so the SAMD21 was selected as the main MCU to supplement this. We are looking in to upgrading to the ESP32-C3 in the near future.

The security features on the ESP32-C3 are great!

> Secure Boot, Flash Encryption, Digital Signature and HMAC Peripheral, Trusted Execution Environment (TEE) / DRM

That could open up new use cases. Strange its RSA only (no ECC).

And it's RISC-V based too.

That's quite reasonable.

Agree that C3 would be a good 'upgrade' here. There's no need for a fully featured ESP32 and C3 will save some cost.
