An ESP32-WROOM32 w/ 8MB of internal SPI Flash. A Silicon Labs Zigbee radio.
Cute design. I like it (I spot sub-optimal decoupling though!)
Also Micro-USB in 2025...
Interested to see what comes out of some of the debug ports... And whether the ESP32 firmware is extractable etc. Also interested to see how good the Wi-Fi onboarding process is, hopefully using something better than ESP-Touch...)
