ESP8684-MINI-1-H4 WiFi RISC-V Bluetooth 5.0 Dual-Mode 4MB Flash IoT Dev Board

This high-performance WiFi SoC module is built on the Espressif ESP8684 chip, featuring an advanced RISC-V 32-bit single-core processor with a clock speed up to 120MHz, designed specifically for resource-constrained IoT devices. The module integrates dual wireless connectivity: Wi-Fi (802.1b/g/n) and Bluetooth 5.0 (Bluetooth LE), supporting 2.4GHz bands for fast, stable transmission. With onboard 4MB SPI Flash, it provides ample space for complex firmware and OTA remote updates. Measuring just 13.2mm x 16.6mm, the module uses a PCB-integrated antenna to save valuable internal space in end products. It offers rich peripheral interfaces (GPIO, UART, I2C, SPI, etc.), operates across a wide temperature range of -40°C to 105°C, and is ideal for smart home sensors, industrial control, wearables, and low-power Bluetooth beacons. As a premium wireless communication module, it delivers exceptional value and development flexibility.
