Shrink your IoT projects without sacrificing power! The ESP32-C3 SuperMini features a 32-bit RISC-V core, Wi-Fi, Bluetooth, and a USB-C port, all packed into a tiny 23x18mm footprint.
Sipeed MAIX Bit K210 AI Development Kit w/ 2.4" LCD & M12 Camera ₹6,999.00 
2.8" LCD Touch Display with ESP32 Development Board - WiFi/BT IoT HMI Module ₹2,349.00 
Sipeed Tang Nano 9K FPGA Development Board with 1.14" SPI LCD ₹3,999.00 
Sipeed Tang Nano 4K FPGA Development Board ₹2,599.00 
TTGO ESP32-S3 WiFi and Bluetooth Development Board 1.9 inch ST7789 LCD Touch Display Touch ₹3,399.00 Ultra-Compact RISC-V Power The ESP32-C3 SuperMini departs from traditional architectures by utilizing a cutting-edge 32-bit RISC-V single-core processor. Despite its small size, it brings full 2.4GHz Wi-Fi and Bluetooth capabilities directly to your fingertips, making it an ideal choice for smart home nodes, wireless sensor networks, and miniature wearables. The board is remarkably tiny, measuring just 23mm in length and 18mm in width.
Modern Interface and Controls Forget fragile Micro-USB connectors; the SuperMini is equipped with a modern, reversible USB C type port for reliable power and data transfer. The front of the board is intelligently laid out, featuring a dedicated Bootloader Button (BOOT) and a Reset Button (RST) for easy flashing and troubleshooting. It also includes a Power LED to indicate active voltage and an independent LED Indicator tied to the GPIO for user-programmable feedback.
Breadboard Friendly and Expandable Despite its "Super Mini" footprint, the board breaks out a highly usable array of pins. The edges feature a standard 2.54mm pitch layout, allowing you to solder the included 8-pin male headers for seamless breadboard prototyping. The silkscreen on the back of the board clearly labels the power pins (5V, G, 3.3) and the available GPIO pins (0, 1, 2, 3, 4 on one side; 5, 6, 7, 8, 9, 10, 20, 21 on the other). These pins fully support UART, I2C, and SPI communication interfaces.

Key Applications and Projects
Wearable Technology: Utilizing the tiny 23x18mm footprint to sew the microcontroller into clothing or embed it into a smartwatch housing.
Miniature Smart Home Nodes: Hiding the board inside small 3D-printed enclosures to create discreet Wi-Fi-enabled temperature sensors or smart buttons.
Bluetooth Beacons: Using the ESP32-C3's Bluetooth capabilities to create localized presence-detection beacons for home automation triggers.
Unlock New Capabilities (Project Evolution) The Ultimate Wi-Fi Macro Key: Capitalize on the SuperMini's compact size and USB-C port to build a custom, single-key macro pad! Wire a premium mechanical keyboard switch to one of the GPIO pins (e.g., pin 9). Program the 32-bit RISC-V chip to connect to your local Wi-Fi and act as a network trigger. When you press the physical key, the board can send a wireless webhook to Home Assistant to execute complex routines—like dimming the lights, turning on your PC, and closing the blinds—all from a device smaller than a postage stamp!
1 x ESP32-C3 SuperMini Board
2 x 8-Pin Male Headers (Unsoldered)
1. What microcontroller chip is used on this board? The board is powered by the ESP32-C3 Chip.
2. What CPU architecture does the ESP32-C3 use? Unlike standard ESP32s which use an Xtensa core, the ESP32-C3 features a modern 32-bit RISC-V architecture.
3. Does this board have Wi-Fi and Bluetooth? Yes, the ESP32-C3 natively supports 2.4GHz Wi-Fi and Bluetooth Low Energy (BLE).
4. What type of USB port does it have? The board is equipped with a modern USB C type connector.
5. What are the exact dimensions of the board? The board measures 23mm in length and 18mm in width.
6. What are the two buttons on the top of the board? There is a Bootloader Button (labeled BOOT) used for entering flashing mode, and a Reset Button (labeled RST) used to restart the microcontroller.
7. Are header pins included? Yes, the package includes two loose 8-pin male headers that you can solder onto the board for breadboard use.
8. What do the LEDs indicate? There is a Power LED that indicates the board is receiving voltage, and a separate LED Indicator that you can program in your code.
9. What is the frequency of the onboard crystal oscillator? The board features a 40.000 MHz Crystal Oscillator.
10. What logic voltage do the GPIO pins use? Like all ESP32 chips, the GPIO pins operate strictly on 3.3V logic. Connecting 5V logic signals directly to the GPIO pins may damage the processor.
11. Can I power the board from a battery? Yes, you can supply a regulated 3.3V to the 3.3 pin or a 5V source (like a USB power bank or 5V boost converter) to the 5V pin, utilizing the onboard Voltage regulator.
12. Does it have a dedicated battery charging circuit? No, this minimalist board does not include a LiPo battery management or charging circuit.
13. Which pins are available for use? According to the silkscreen, the available GPIO pins are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, and 21.
14. Where are the power pins located? The power pins (5V, G for Ground, and 3.3 for 3.3V) are located near the top edge on one side of the board.
15. Does this board support I2C and SPI? Yes, the ESP32-C3's internal multiplexer allows you to assign I2C, SPI, and UART hardware interfaces to almost any of the available GPIO pins.
16. How do I put the board into bootloader mode? If the board fails to auto-reset during programming, hold down the Bootloader Button (BOOT), press and release the Reset Button (RST), and then release the Bootloader Button.
17. What settings should I use in the Arduino IDE? You can typically select the "ESP32C3 Dev Module" from the ESP32 board manager. Ensure "USB CDC On Boot" is enabled so the serial monitor functions properly via the USB-C port.
18. What does "Super Mini" refer to? "Super Mini" is printed on the silkscreen and refers to the ultra-compact 23x18mm form factor of the development board.
19. What is the red component on the front of the board? The red component near the bottom edge is a ceramic chip antenna for the Wi-Fi and Bluetooth radios.
20. Can I program this with MicroPython? Yes, the ESP32-C3 is fully supported by MicroPython, allowing you to write simple and efficient Python scripts to control the hardware.
