2 pcs ESP32-C3 SuperMini Development Board 22.52 x 18 mm with Unattached Pins WiFi and Bluetooth 5.0 4 MB Flash USB-C for Arduino and IoT
You already have the maximum available quantity in your cart.
The package includes two ESP32-C3 SuperMini development boards, which are among the smallest wireless modules for hobby electronics. Each board measures only 22.52 x 18 mm, making it suitable for miniaturised sensor enclosures, switches, or wearable devices. The performance is provided by the ESP32-C3FN4 chip with a RISC-V processor up to 160 MHz, 400 KB SRAM, and 4 MB of integrated Flash memory. The pin headers are included separately and unattached, allowing you to solder them as needed or mount the module directly onto your own circuit board. The double pack is ideal for projects where two devices communicate with each other.
The modules support WiFi 802.11b/g/n and Bluetooth 5.0 LE, enabling them to send data to a home network, be controlled from a phone, or exchange information with each other. There are 11 GPIO inputs and outputs with PWM support, 4 analogue inputs, and I2C, SPI, and UART buses. The USB-C interface is used for both power supply and programming without the need for an additional converter.
- Chip – ESP32-C3FN4 with a 32-bit single-core RISC-V processor up to 160 MHz and FPU
- Memory – 400 KB SRAM, 384 KB ROM, and 4 MB Flash
- Wireless Connection – WiFi 802.11b/g/n 2.4 GHz and Bluetooth 5.0 LE
- Inputs and Outputs – 11 GPIO with PWM support and 4 analogue inputs ADC 12 bit
- Buses – I2C, SPI, and 2x UART
- Interface – USB-C for power and programming
- Buttons – RESET and BOOT
- Deep Sleep Current – approximately 43 μA
- Power Supply – 5 V via USB-C, output 3.3 V up to 500 mA
- Development Board Dimensions – 22.52 x 18 mm
- Programming – Arduino IDE, MicroPython, and ESP-IDF
- Package Contents – 2 ESP32-C3 SuperMini development boards and 4 unattached pin headers
The GPIO pins can handle a maximum of 3.3 V, so do not apply 5 V to them. The module can be powered via USB-C, from a 3.7 to 5 V battery on the 5 V pin, or with a stabilised voltage of 3.3 V directly on the 3.3 pin. The integrated blue LED on GPIO8 makes it easier to test the uploaded program. Solder the pin headers carefully and protect the boards from moisture and static electricity.
The pair of ESP32-C3 SuperMini modules is a cost-effective choice for anyone building multiple sensors or wanting to have a spare unit on hand. The consumption of approximately 43 μA in deep sleep allows for long battery life, and the RESET and BOOT buttons simplify debugging. Programming can be done in the Arduino IDE, MicroPython, and ESP-IDF environments, making it suitable for both beginners and experienced developers. The boards are useful in smart homes, for measuring temperature and humidity, and in educational projects.
