ESP32C3 PRO MINI is an IoT mini development board based on the ESP32-C3 WiFi/Bluetooth dual-mode chip. The ESP32-C3 features a 32-bit RISC-V CPU with an FPU (floating point unit) capable of 32-bit single-precision operations, delivering strong computing performance. It offers excellent RF performance and supports IEEE 802.11 b/g WiFi and Bluetooth 5 (LE) protocols. The board includes a ceramic antenna and an IPEX antenna connector to enhance wireless signal strength. Designed with a compact and sleek form factor and a single-sided component layout, it provides a rich set of interfaces, including 11 digital I/O pins that support PWM and 4 analog I/O pins that support ADC. It supports multiple serial interfaces including UART, I2C, and SPI. Onboard features include a reset button and a bootloader mode button. This board is designed for high performance, low power consumption, and cost efficiency, making it suitable for low-power IoT and wireless wearable applications.Specifications: - CPU: ESP32-C3, 32-bit RISC-V single-core processor, up to 160 MHz - WiFi: IEEE 802.11 b/g, 2.4 GHz, supports Station, SoftAP, SoftAP+Station, and mixed modes - Bluetooth: Bluetooth 5 (LE) - Ultra-low power consumption: deep sleep current approximately 43 A - Memory: 400 KB SRAM, 384 KB ROM, onboard 4 MB Flash - Security: supports AES-128/256, hash, HMAC, cryptographic hardware acceleration, digital signature, and secure boot - Interfaces: 1x I2C, 1x SPI, 2x UART, 11x GPIO (PWM), 4x ADC - Onboard LED: blue, connected to GPIO8 - Color: Blue - Material: PCB - Form: Unsoldered Package Includes: 1 x Mini development board 2 x Pin headers (random colors, no color selection available) Note: The package includes only the items listed above.
