Overview

The ESP32-C3-DevKitM-1 is an entry-level development board based on the ESP32-C3-MINI-1 module, featuring a 32-bit RISC-V single-core processor running at 160 MHz. It provides integrated 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) connectivity in a compact, breadboard-friendly form factor. The board includes a 4 MB SPI flash and exposes most of the module's I/O pins to headers for easy prototyping.

Why Choose This Part

The transition to a RISC-V architecture provides a modern, open-standard core with a 160 MHz clock and FPU. It includes robust hardware security features like an RSA accelerator and HMAC, which are critical for secure IoT deployments. Additionally, the integrated USB-to-UART bridge and 400 KB RAM offer a streamlined development experience for small-to-medium firmware projects.

Applications

Smart Home Nodes

Ideal for Wi-Fi connected light switches, sensors, and plugs that require secure boot and flash encryption.

Industrial Sensors

Utilizes the built-in TWAI controller (CAN 2.0 compatible) and ADC for monitoring industrial machinery.

Battery-Powered IoT

Suited for low-power applications with a 130 uA light-sleep current and 5 uA standby current.

Cloud Connectivity Gateways

Acts as a bridge between Bluetooth LE peripherals and Wi-Fi based cloud services using the 2.4 GHz transceiver.
