ESP32-C3M Specification

PublishTime：2022-12-16

●Product Overview
■ESP32-C3M 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 internet of things (IoT), mobile devices, wearable electronics, smart home, 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 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.
■ESP32-C3M provides a wealth of peripheral interfaces, including UART，PWM，SPI，I2S， I2C，ADC，temperature sensor and there are 15 GPIOs.
■ESP32-C3M has a variety of unique hardware safety mechanisms.The hardware encryption accelerator supports AES、SHA and RSA algorithm. Among them, RNG, HMAC and Digital Signature modules provide more security features. Other security features include flash encryption and se-cure boot signature verification, etc. The perfect security mechanism enables the chip to be perfectly applied to various encryption products.
■ESP32-C3M module supports low-power Bluetooth：Bluetooth5，Bluetooth mesh.
■Bluetooth rate support: 125Kbps, 500Kbps, 1Mbps, 2Mbps. Support broadcast extension, multi-broadcasting, channel selection.
