Overview

The ESP32-C3-MINI-1 is a compact, 2.4 GHz Wi-Fi and Bluetooth LE 5.0 module powered by a single-core RISC-V processor running at 160 MHz. It features a built-in PCB trace antenna and 4MB of integrated flash in a small 13.2mm x 16.6mm surface-mount package, making it ideal for space-constrained IoT applications.

Why Choose This Part

The RISC-V core provides an open-standard architecture with 400kB SRAM, sufficient for complex TLS/SSL security stacks. Its integrated coexistence mechanism allows Wi-Fi and Bluetooth to share the same antenna efficiently without performance degradation.

Applications

Smart Lighting Control
Compact enough to fit inside bulb bases or small wall switches for Wi-Fi and BLE mesh control.
Battery-Powered Sensors
Utilizes a 130uA sleep mode and high-sensitivity (-104dBm) receiver to maintain long-range connectivity while preserving battery life.
Industrial Protocol Conversion
Uses UART, SPI, and I2C interfaces to bridge legacy industrial equipment to cloud platforms via 802.11b/g/n.
Wearable Device Hub
Small footprint and Bluetooth 5.0 support allow it to act as a gateway for health-monitoring peripherals.
