BMT ESP32-C3 Mini WiFi Bluetooth 5 RISC-V Dev Board

The BMT ESP32-C3 Development Board (Super Mini) is a compact and energy-efficient IoT microcontroller platform powered by the advanced ESP32-C3 RISC-V processor. Designed for modern embedded applications, it combines WiFi connectivity and Bluetooth 5 (BLE) with a highly efficient single-core architecture, making it ideal for space-constrained and low-power projects.

At its core is a 32-bit RISC-V CPU running up to 160MHz, equipped with a floating-point unit (FPU) for improved computational performance. This board delivers reliable wireless communication via 2.4GHz WiFi (802.11 b/g/n) and Bluetooth Low Energy (BLE 5.0), enabling seamless integration into IoT ecosystems.

Despite its ultra-compact size, the ESP32-C3 offers a wide range of interfaces including GPIO, ADC, PWM, UART, SPI, and I2C, allowing developers to connect sensors, displays, and peripherals with ease. Its low power consumption, especially in deep sleep mode (~43 A), makes it ideal for battery-powered and long-term deployments.

The board supports development using Arduino IDE and ESP-IDF, offering flexibility for both beginners and advanced developers. Integrated hardware security features such as encryption acceleration, secure boot, and digital signature support ensure data protection and system integrity.
