ESP32-H2 Mini Development Board - Zigbee 3.0, Thread & Bluetooth 5 LE - Soldered

The Waveshare ESP32-H2-Zero is a tiny development board built around the ESP32-H2, Espressif's low-power chip for Zigbee 3.0, Thread and Bluetooth 5 (LE). It is designed for battery-powered smart home sensors, Matter over Thread devices, Zigbee end devices and Bluetooth Mesh networks. This version comes with pin headers pre-soldered, ready to plug straight into a breadboard.

Note: the ESP32-H2 does not have Wi-Fi. If your project needs Wi-Fi as well as Zigbee or Thread, see the ESP32-C5-Zero, which adds dual-band Wi-Fi 6.

A RISC-V processor, 4MB Flash, USB-C and an onboard RGB LED fit into a thumbnail-sized footprint, and its castellated edges let it be soldered directly onto a PCB like a module. It can be programmed with ESP-IDF or the Arduino IDE.
