1. Overview
®
ESP32-C3 family is an ultra-low-power MCU-based SoC solution that supports 2.4 GHz Wi-Fi and Bluetooth
Low Energy (Bluetooth LE). With its state-of-the-art power and RF performance, this SoC is an ideal choice for a
wide variety of application scenarios relating to Internet of Things (IoT), smart home, industrial automation, health
care, and consumer electronics.
At the core of this chip is a 32-bit RISC-V single-core processor that operates at up to 160 MHz. The chip
supports application development, without the need for a host MCU.
ESP32-C3 family provides a highly-integrated way to implement Wi-Fi and Bluetooth LE technologies using a
complete RF subsystem, including a antenna switch, RF balun, power amplifier, low noise amplifier (LNA), filter,
power management unit, calibration circuits, etc. As a result, PCB size has been greatly reduced.
With its advanced calibration circuitry, ESP32-C3 can dynamically adjust itself to remove external circuit
imperfections or adapt to changes in external conditions. As such, the mass production of ESP32-C3 family
does not require expensive and specialized Wi-Fi test equipment.
