The ESP8684-DevKitM-1-H4X Development Board is an entry-level development platform built around the ESP8684-MINI-1 module with 4 MB SPI Flash. It combines Wi-Fi and Bluetooth LE connectivity, making it ideal for IoT, smart home, and wireless embedded applications. The board features a Micro-USB interface for power and programming, an onboard USB-to-UART bridge supporting data transfer up to 3 Mbps, and a 5 V to 3.3 V LDO regulator for stable operation. Most GPIOs are exposed through dual pin headers, enabling quick prototyping on breadboards or with jumper wires. Boot and Reset buttons simplify firmware flashing, while the onboard RGB LED assists with application status indication. Compatible with ESP-IDF and ESP-AT firmware, it offers a reliable platform for embedded development and rapid prototyping.
