Espressif Systems ESP32-H BLE & IEEE 802.15.4 Modules


Espressif Systems ESP32-H BLE and IEEE 802.15.4 Modules are powerful, generic BLUETOOTH® Low Energy and IEEE 802.15.4 combo modules featuring the ESP32-H2 chip. The ESP32-H is suitable for building IoT applications with high requirements for power consumption.

The Espressif ESP32-H module is small-sized and pin-to-pin compatible with the ESP32-C3-MINI and ESP32-C6-MINI modules.
