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) for wireless connectivity. 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 pin layout is compatible with the ESP32-H2-DevKitM-1 board, enabling easy integration with a wide range of peripherals and offering strong expandability. The board features a stamp-hole design for direct soldering and embedding into custom applications. Software development is supported via the official ESP-IDF framework, with sample code and documentation available to help users get started quickly.
