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:

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).

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