ESP32-H2 is an entry-level development board equipped with low-power Bluetooth and IEEE 802.15.4 dual-mode module ESP32-H2-MINI-1. Most of the pins of the module on the board have been pinned out to the pins on both sides of the board, so developers can easily connect a variety of peripheral devices via jumpers according to actual needs, and also plug the board into a breadboard for use.
