ESP-C3-M1-I is a WiFi module developed by Shenzhen Ai-Thinker Technology Co., Ltd. The module’s core processor chip ESP32-C3 is a highly integrated low-power WiFi and Bluetooth system-on-chip (SoC), designed for the Internet of Things (IoT), mobile devices, wearable electronic devices, smart homes application, etc. The ESP32-C3 chip has industry-leading low power consumption performance and radiofrequency performance, and supports WiFi IEEE802.11b/g/n protocol and BLE 5.0. The chip is equipped with a RISC-V 32-bit single-core processor with a working frequency of up to160MHz.
Support secondary development without using other microcontrollers or processors. The chip has built-in 400 KB SRAM, 384 KB ROM, 8KB RTC SRAM, and built-in 4MBFlash. 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 ESP-C3-M1-I module provides a wealth of peripheral interfaces, including UART, PWM, SPI, I2S, I2C, ADC, temperature sensor and up to 15 IO interfaces. The ESP-C3-M1-I module has a variety of unique hardware security 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. Other security features include Flash encryption and secure boot (secure boot) signature verification. The perfect security mechanism enables the chip to be perfectly applied to various encryption products. The ESP-C3-M1-I module supports low-power Bluetooth: Bluetooth5, Bluetooth mesh. Bluetooth rate support: 125Kbps, 500Kbps, 1Mbps, 2Mbps. Support broadcast extension, multi-broadcasting, channel selection
