ESP32-C3 SuperMini Development Board with IP-EX Interface Wi-Fi+BT Microcomputers ESP32 C3 Chip. There is an IP-EX antenna holder on the top of the board, which can be connected to an external 2.4G antenna. The ESP32C3SuperMini is an IoT mini development board based on the ESP32-C3 WiFi/Bluetooth dual-mode chip.The ESP32-C3 is a 32-bit RISC-V CPU containing a FPU (Floating Point Unit) for 32-bit single-precision arithmetic with powerful computational capabilities. It has excellent RF performance and supports IEEE 802.11 b/g/n WiFi and Bluetooth 5 (LE) protocols. It also features a small and compact form factor combined with a single-sided surface mount design. It is equipped with a rich set of interfaces, with 11 digital I/Os that can be used as PWM pins and 4 analogue I/Os that can be used as ADC pins, and it supports four serial interfaces, including UART, I2C and SPI. There is also a small reset button and a bootloader mode button on the board. Taken together, the ESP32C3SuperMini is positioned as a high-performance, low-power, cost-effective IoT mini development board for low-power IoT applications and wireless wearable applications.
