ESP32 C3 Super Mini Description
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 performance and supports IEEE 802.11b b/g/n WiFi and Bluetooth 5 (LE) protocols. The board comes with an external antenna to enhance signal strength for wireless applications. It also has a small and delicate form factor combined with a single-sided surface mount design. It is equipped with plenty of interfaces, 11 digital GPIOs that can be used as PWM pins and 4 analog I/Os that can be usedas 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.
