Overview

The ESP32-C3-MINI-1-N4 is a compact Wi-Fi and Bluetooth LE 5.0 module powered by a 32-bit RISC-V single-core processor running at up to 160 MHz. It integrates 4 MB of embedded flash and 400 KB of SRAM into a small 13.2 mm x 16.6 mm form factor with an on-board PCB trace antenna.

Why Choose This Part

This module provides a cost-effective migration path to the RISC-V architecture while maintaining compatibility with the extensive ESP-IDF ecosystem. Its high level of integration, including a built-in oscillator and PCB antenna, reduces the external Bill of Materials and simplifies RF layout requirements.

Applications

Smart Home Lighting
Utilize Wi-Fi connectivity and PWM peripherals to control LED strips and smart bulbs with remote management.
Industrial Sensor Nodes
Collect data via ADC, SPI, or I2C and transmit via Bluetooth Mesh or Wi-Fi in factory environments.
Battery-Powered Wearables
Leverage the 5 uA standby current and 130 uA light-sleep modes to extend battery life in portable electronics.
Retail Asset Tracking
Use Bluetooth 5.0 LE capabilities for proximity sensing and beacon monitoring in logistical applications.
