BDD ESP32-C3 Super Mini V2 Board Wi-Fi & Bluetooth 5.0 USB-C IoT Dev Board

The BDD ESP32-C3 Super Mini V2 is a compact, high-performance development board tailored for IoT, smart home, and wireless applications. Powered by the Espressif ESP32-C3FH4 32-bit RISC-V single-core processor running at up to 160MHz, it combines Wi-Fi 4 and Bluetooth 5.0 Low Energy in a tiny, ultra-low power package.

This V2 version upgrades usability with a native USB-C port, eliminating the need for external USB-to-serial adapters. It supports CDC, DFU, and USB HID, enabling USB device development alongside its wireless capabilities.

With 4MB of onboard flash, 400kB SRAM, 16kB cache, and 8kB RTC SRAM, the board offers ample memory for firmware and applications. It features up to 21 GPIO pins, supporting multiple digital interfaces including UART, SPI, I2C, PWM, ADC, and I2S, making it suitable for sensors, actuators, BLE peripherals, and embedded electronics projects.

The board comes with onboard LEDs (Power, user-controllable, RGB), an onboard antenna, and an external antenna option via IPEX MHF-I socket. It's fully compatible with Arduino IDE, ESP-IDF, and MicroPython, offering flexibility for both beginners and advanced developers.
