ESP32-C3 Super Mini

The ESP32 C3 SuperMini is an loT mini development board based on the Espressif ESP32-C3 WiFi/ Bluetooth dual-mode chip. 

The ESP32-C3 is a 32-bit RISC-V CPU that contains the FPU (floating point unit) for 32-bit single-precision operations with powerful computing power. It has excellent F performance and supportsIEEE 802.11b /g/n WiFi and Bluetooth 5 (LE) protocols.

The board comes with an internal ceramic antenna. It also has a small form factor combined with a single-sided surface mount design. It is equipped with an array of interfaces, with 11 digital I/ OS that can be used as PWM pins and 4 analog I/OS that can be used as ADC pins. It supports four serial interfaces: UART, I2C and SPI. The board also has a small reset button and a boot loader mode button. The ESP32-C3-SuperMini is positioned as a high-performance, low power, cost-effective IoT mini development board for low-power IoT applications and wireless wearable applications.

Technical Specification:

• Powerful CPU: ESP32-C3, 32-bit RISC-V single-core processor, running up to 160 MHz.
• WiFi: 802.11b/g/n protocol, 2.4GhHz, support Station mode, SoftAP mode, SoftAP+Station mode,
  hybrid mode
• Bluetooth: Bluetooth 5.0 Low Energy
• Ultra-low power consumption: deep sleep power consumption of about 43µA
• Rich board resources: 400KB SRAM, 384KB ROM built-in 4Mflash.
• Chip model: ESP32C3FN4
• Ultra-small size: As small as the thumb (22.52x18mm) classic shape, suitable for wearables and small projects
• Reliable security features: Encryption hardware accelerators that support AES-128/256, hashing, RSA, HMAC,digital signatures, and secure startup
• Rich interface: 1x12C, 1xSPI, 2xUART, 11xGPIO(PWM), 4xADC
• Single-sided components, surface mount design
• Onboard LED blue light: GPIO8 pin
• Connector- USB-C

The board can be powered with 3.3 - 6V (on the 5V pin). Please note, however, powering by USB-C and 5 or 3.3V pin cannot be used simultanously.

Pin connectors are included but not soldered to the board (as it can be surface mounted on a bigger project board).

Attention: If you are flashing for the first time, you need to get the ESP32-C3 into the download mode manually. To do so, press and hold the BOOT button and then press the RESET button once. After that release the BOOT button. Otherwise, the board will reset USB connection every few seconds. Next flashes do not require this procedure.

Fully supported by Arduino and ESPHome (for Home Assistant).
