BMT D1 Mini ESP32 Dev Board Dual-Core Wi-Fi & Bluetooth MCU with CP2104

The BMT D1 Mini ESP32 Development Board is a compact yet powerful microcontroller platform based on the ESP32 dual-core SoC, combining high performance, low power consumption, and extensive wireless connectivity in a familiar D1 Mini-style footprint. Designed for developers, makers, and IoT engineers, this board delivers robust computing power with built-in Wi-Fi and Bluetooth, making it ideal for modern connected applications.

Featuring a CP2104 USB-to-UART converter, the board offers stable USB communication and effortless programming directly from your PC, while maintaining compatibility with popular development environments such as Arduino IDE, ESP-IDF, and MicroPython.

Powerful Dual-Core Processing Performance

At the heart of the board is the Xtensa 32-bit LX6 dual-core processor, capable of delivering up to 600 DMIPS of computing performance. This makes the ESP32 well-suited for multitasking applications such as sensor data processing, wireless communication, user interfaces, and real-time control.

The integrated memory architecture provides:

• 448 KB ROM for bootloader and system functions
• 520 KB SRAM for application data and runtime operations
• 16 KB RTC SRAM, enabling data retention and ultra-low-power sleep modes

Additionally, the ESP32 supports QSPI external Flash and SRAM expansion, allowing up to 4 external memory devices, each up to 16 MB, for advanced applications.

Integrated Wi-Fi and Bluetooth Connectivity

The ESP32 is a single 2.4 GHz Wi-Fi and Bluetooth combo chip, manufactured using TSMC ultra-low-power 40 nm technology. This ensures excellent RF performance, high reliability, and low energy consumption across a wide range of operating scenarios.

Wireless capabilities include:

• 2.4 GHz Wi-Fi (802.11 b/g/n)
• Bluetooth Classic and Bluetooth Low Energy (BLE)
• Reliable performance in noisy RF environments

These features make the board perfect for IoT devices, smart home systems, wireless sensors, and remote monitoring solutions.

D1 Mini-Compatible Form Factor

This ESP32 board is designed in a D1 Mini-style form factor, matching the familiar footprint and pin layout used by Wemos D1 Mini boards. This allows:

• Easy integration into existing D1 Mini projects
• Compatibility with many D1 Mini shields and accessories
• Compact installation in space-constrained enclosures

Despite its small size, the board exposes a rich set of GPIOs, communication interfaces, and power options.

CP2104 USB Interface for Easy Programming

The onboard CP2104 USB-to-UART chip ensures reliable USB connectivity for flashing firmware and serial debugging. Simply connect the board to your computer using a USB cable and start programming-no external adapters required.

Power Efficiency and Flexible Supply Options

The board operates within a supply voltage range of 2.2V to 3.6V, making it suitable for battery-powered designs and low-energy applications. Combined with the ESP32's deep-sleep and power-management features, it enables long-term operation in energy-constrained environments.
