Product Overview
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.
