ESP-C3-12F is a Wi-Fi module developed by Ai-Thinker. This module core processor ESP32-C3 is a Wi-Fi+ BLE combination of system-level chips (SoC), designed for various applications such as the internet of things (IoT), mobile devices, wearable electronics, smart homes, etc.

ESP32-C3 with industry-leading low power and RF performance, supporting Wi-Fi IEEE802.11b/g/n agreements and BLE 5.0. ESP32-C3 chip is equipped with 32-bit RISC-V single-core processor, operating frequency up to 160 MHz. The chip is support to have secondary development without using other microcontrollers or processors. The chip has a built-in 400 KB SRAM,384 KB ROM,8KB RTC SRAM.

Also, the chip support external Flash while it has built-in 4Mbit Flash. ESP32-C3 chip supports a variety of low-power consumption working states, which can meet the power consumption requirements of various application scenarios. The chip’s unique features such as fine clock gating function, dynamic voltage clock frequency adjustment function, and RF output power adjustable function can achieve the best balance between communication distance, communication speed, and power consumption.

ESP-C3-12F provides a wealth of peripheral interfaces, including UART,PWM,SPI,I2S,I2C,ADC,temperature sensors and there are 15 GPIOs.

ESP-C3-12F has a variety of unique hardware safety mechanisms. The hardware encryption accelerator supports AES、SHA and RSA algorithms. Among them, RNG, HMAC, and Digital Signature modules provide more security features. Other security features include flash encryption and secure boot signature verification, etc. The perfect security mechanism enables the chip to be perfectly applied to various encryption products.
