ESP32-C3 series module
ESP32-C3 series module
Overview
ESP32-C3 series modules (hereinafter referred to as modules) are Wi-Fi modules developed by Shenzhen Ai-Thinker Technology Co., Ltd. The chip ESP32-C3 is equipped with a 32-bit RISC-V single-core processor with a working frequency of up to 160 MHz. It supports secondary development without use of other microcontrollers or processors. It is a highly integrated low-power Wi-Fi plus Bluetooth system-on-chip (SoC), designed for various applications such as the Internet of Things (IoT), mobile devices, wearable electronic devices, and smart homes.
The module supports Wi-Fi IEEE 802.11b/g/n protocol and BLE 5.0 protocol stack, and only supports 2.4G frequency band, not 5G frequency band.
The chip has built-in 400 KB SRAM, 384 KB ROM, 8KB RTC SRAM, built-in 4MB Flash and also supports external Flash. The 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 rate and power consumption.
The module provides a wealth of peripheral interfaces, including UART, PWM, SPI, I2S, I2C, ADC.
The module 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 (Digital Signature) modules provide more security features.
The module supports low-power Bluetooth: Bluetooth5, Bluetooth mesh, Bluetooth rate support: 125Kbps, 500Kbps, 1Mbps, 2Mbps. Support broadcast extension, multi-broadcasting, channel selection.
