ESP32-C3 SuperMini Dev Board – WiFi & Bluetooth 5.0 Type-C

ESP32-C3 SuperMini Development Board – Compact WiFi & BLE 5.0 for IoT & DIY Projects

Meet the ESP32-C3 SuperMini Development Board — an ultra-compact yet remarkably powerful microcontroller board built on Espressif's ESP32-C3 chip. Whether you're prototyping a smart sensor, building a wearable device, or developing a battery-powered IoT product, this tiny board packs everything you need into a footprint barely larger than a postage stamp.

Made in Mainland China.

Why Choose the ESP32-C3 SuperMini?

• Powerful RISC-V Core: Features the Espressif ESP32-C3 32-bit RISC-V single-core processor running at up to 160 MHz, with 400 KB SRAM and 4 MB Flash — more than enough headroom for complex IoT firmware and real-time data processing.
• Dual Wireless Connectivity: Integrated 2.4 GHz 802.11 b/g/n WiFi and Bluetooth 5.0 LE (Low Energy) in a single chip — no external wireless modules needed. This cuts your project's component count, reduces BOM cost, and speeds up your development cycle.
• Ultra-Compact PCB (23.83 × 17.65 mm): Built on a high-density, heat-resistant FR-4 fiberglass substrate, the SuperMini slips into space-constrained enclosures with ease — ideal for wearables, miniature smart sensors, and mini IoT products.
• Type-C USB Interface: A modern Type-C port handles both power and programming. Gold-plated 0.1" pitch pin headers are fully breadboard-compatible, making prototyping wiring clean and straightforward.
• Ultra-Low Power Consumption: Advanced power management delivers just 43 µA in deep sleep mode, dramatically extending battery life for portable and field-deployed devices.

Frequently Asked Questions

Q: Is the ESP32-C3 SuperMini compatible with the Arduino IDE?

A: Yes — the ESP32-C3 SuperMini is fully supported by the Arduino IDE via the Espressif Arduino Core for ESP32. Simply add the ESP32 board package to your Arduino IDE, select the appropriate ESP32-C3 board profile, and you can program it using familiar Arduino syntax. It also supports MicroPython and ESP-IDF for more advanced development workflows.

Q: Does this board include a USB cable or battery?

A: The package includes 1 × ESP32-C3 SuperMini development board only. No USB cable or battery is included. You will need a standard Type-C USB cable (sold separately) to connect the board to your computer for programming and power.

Q: How small is the board, and will it fit a standard breadboard?

A: The board measures just 23.83 × 17.65 mm — extremely compact. The 0.1" (2.54 mm) standard-pitch gold-plated pin headers are fully compatible with standard full-size and half-size breadboards, making it easy to prototype circuits without soldering.

Q: What is the deep sleep current consumption of the ESP32-C3 SuperMini?

A: In deep sleep mode, the board consumes approximately 43 µA, making it an excellent choice for battery-powered IoT applications where extended field operation is required between charges or battery replacements.
