ESP32C3SuperMini is an IoT mini development board based on the EspressifESP32-C3 WiFi/Bluetooth dual-mode chip. ESP32-C3 is a 32-bit RISC-VCPU, including FPU (Floating Point Unit), which can perform 32-bit single- operations: it has powerful computing capabilities. It has excellent performance supporting IEEE 802.11 b/g WiFi and Bluetooth 5 (LE) protocols. The board comes with an external antenna to enhance signal strength for wireless applications. It also features a small, sophisticated form factor combined with a single-sided mount design. It is equipped with rich interfaces, with 11 digital I/0s that can be used as PWM pins and 4 analog 1/0s that can be used as ADC pins. It supports four serial interfaces including UART, 12C and SPI. There's also a small reset button and a bootloader mode button on the board. Powerful CPU: ESP32-C3, 32-bit RISC-V single-core processor running at up to 160MHz WiFi: 802.11b/g protocol, 2.4GhHz Bluetooth:Bluetooth 5.0 Ultra-low power consumption: Deep sleep power consumption is about 43μA Rich board resources: 400KBSRAM, 384KBROM Built-in 4Mflash Chip model: ESP32C3FN4 Classic extra small size: as small as thumb Form factor for wearables and small projects Rich interfaces: 1x12C, 1xSPI, 2xUART, 11xGPI0(PWM), 4xADC Single-sided component, mount design Onboard LED blue light: GPI08 pin Colour:As Shown Material:plastic Package Contents: 3 x ESP32-C3 development board(pin header not soldered) Only the above package content, other products are not included.
