The ESP32-C3 features a 32-bit RISC-V CPU with an FPU (Floating-Point Unit), capable of performing 32-bit single-precision operations and delivering powerful computing performance. It offers excellent RF performance and supports IEEE 802.11 b\/g\/n Wi-Fi and Bluetooth 5 (LE) protocols. The board comes with an external antenna to enhance signal strength for wireless applications. It also features a compact and refined form factor with a single-sided surface-mount design. The board is equipped with a rich set of interfaces, including 11 digital I\/O pins that can be used as PWM pins and 4 analog I\/O pins that can be used as ADC pins. It supports four serial communication interfaces, including UART, I2C, and SPI. The board also features a small Reset button and a Bootloader mode button.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eWith these features, the board is positioned as a high-performance, low-power, and cost-effective IoT mini development board, suitable for low-power IoT applications and wireless wearable devices.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/div\u003e\u003cdiv\u003e* Powerful CPU: ESP32-C3, 32-bit RISC-V single-core processor running at up to 160MHz.\u003c\/div\u003e\u003cdiv\u003e* Wi-Fi: Supports IEEE 802.11 b\/g\/n at 2.4GHz, including Station mode, SoftAP mode, SoftAP + Station mode, and promiscuous mode.\u003c\/div\u003e\u003cdiv\u003e* Bluetooth: Bluetooth 5.0.\u003c\/div\u003e\u003cdiv\u003e* Ultra-Low Power Consumption: Deep-sleep power consumption of approximately 43μA.\u003c\/div\u003e\u003cdiv\u003e* Rich Onboard Resources: 400KB SRAM, 384KB ROM, and 4MB built-in Flash memory.\u003c\/div\u003e\u003cdiv\u003e* Chip Model: ESP32C3FN4.\u003c\/div\u003e\u003cdiv\u003e* Ultra-Compact Size: Measures just 22.52 x 18mm, featuring a compact, thumb-sized design ideal for wearable devices and small-scale projects.\u003c\/div\u003e\u003cdiv\u003e* Reliable Security Features: Hardware cryptographic acceleration supporting AES-128\/256, hashing, RSA, HMAC, digital signatures, and secure boot.\u003c\/div\u003e\u003cdiv\u003e* Versatile Interfaces: 1 x I2C, 1 x SPI, 2 x UART, 11 x GPIO (PWM), and 4 x ADC.\u003c\/div\u003e\u003cdiv\u003e* Single-Sided Design: Single-sided component placement with a surface-mount design.\u003c\/div\u003e\u003cdiv\u003e* Onboard Blue LED: Connected to GPIO8.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cb\u003eExternal Power Supply:\u003c\/b\u003e\u003c\/div\u003e\u003cdiv\u003e* To power the board using an external power supply, connect the positive (+) terminal to the 5V pin and the negative (-) terminal to GND.
