ESP32-H2-DEV-KIT-N4 is a compact, feature-rich development board based on the ESP32-H2-MINI-1-N4 module. It features a RISC-V 32-bit single-core processor running up to 96 MHz, with 4 MB of integrated Flash memory. The board supports Bluetooth 5 and IEEE 802.15.4 (Zigbee 3.0 and Thread) wireless connectivity with strong RF performance.It includes multiple peripheral interfaces such as SPI, UART, I²C, I²S, LED PWM, and ADC. A USB-C interface is provided, supported by onboard CH343 (USB-to-serial) and CH334 (USB hub) chips for seamless USB and UART development.The board uses a stamp-hole design for easy integration and offers pin compatibility with the ESP32-H2-DevKitM-1 development board, enabling broad peripheral expansion and scalability.Software development is supported via the official ESP-IDF environment, with sample code and tutorials available to help users get started quickly. Typical applications include smart home devices, industrial automation, and consumer electronics.
