Overview

The ESP32-C3-MINI-1-N4X is a compact, highly integrated Wi-Fi and Bluetooth LE 5.0 module based on the RISC-V architecture. It features 4MB of embedded flash and a single-core 160MHz processor, designed to provide cost-effective connectivity for power-sensitive IoT applications. The module's small 13.2mm x 16.6mm footprint and integrated PCB trace antenna make it suitable for space-constrained designs.

Why Choose This Part

This module transitions from Xtensa to a RISC-V core, offering a modern instruction set and simplified development at a lower price point than previous ESP32 generations. It includes advanced Wi-Fi features like WMM and TX/RX A-MPDU for better throughput, alongside a highly efficient power profile for battery-operated devices.

Applications

Smart Home Appliances
Integrating Wi-Fi and BLE connectivity into small appliances like light switches, plugs, and sensors for remote control and automation.
Industrial IoT Sensors
Deploying battery-powered wireless nodes that require the 130uA light-sleep or 5uA standby current modes to extend field life.
Wireless POS Terminals
Handling secure wireless transactions and peripheral connectivity using the 400KB SRAM and built-in hardware security features.
Health Monitoring Wearables
Collecting sensor data and transmitting it to mobile devices via Bluetooth LE while maintaining a compact physical profile.

Getting Started

Developers can use the Espressif IoT Development Framework (ESP-IDF) or the Arduino IDE for software development. The module is typically evaluated using the ESP32-C3-DevKitM-1 development board. Firmware is flashed via the UART pins, and the internal co-existence mechanism ensures stable performance when using Wi-Fi and Bluetooth simultaneously.
