01 What this can become

A lock, a lamp, a Thread/Zigbee endpoint.

Let a gateway reach the cloud; this board stays local.

02 Hardware

  • Chip: ESP32-H2
  • Radio: BLE 5 + 802.15.4, no Wi-Fi
  • USB: DevKit programming port
  • I/O: small board, enough pins for a local product
  • Watch: do not copy Wi-Fi Station / MQTT examples; pair it with a gateway.

03 When to pick it

Use H2 when the device must not join a router. If it must reach the internet itself, pick C3, C6 or ESP32.
