I was able to run one ESP32 device called TTGO T-display with LNbits code like I wrote below, but I think someone said that this same device can work with Jade hardware wallet firmware.
Jade hardware wallet is very similar with M5StickV K210, I am not exactly sure what components are hidden inside, but I think it's ESP32.
Jade has the shape of a M5stickV but uses ESP32 indeed. So how they managed to use camera e scan QR codes? I believe they were able to achieve this by using efficient C code, instead of micropython.
Jade has support to be compiled and flashed in TTGOs and M5stack Black, Grey, Fire, etc(not k210 M5stickV). I did it myself and it works pretty well. However the firmware for these boards does not have camera support neither air-gapped features, only USB signing on Green Wallet.
