ESP32-C6-MINI-1U
Overview
The ESP32-C6-MINI-1U is a compact Espressif module based on the ESP32-C6 SoC that provides a module option with an external antenna connector (U.FL). It packages the SoC, RF front end and supporting components into a small, ready-to-use module to simplify integration of wireless connectivity into products. The U.FL variant makes it easy to attach an external antenna for improved range or for placement in metal enclosures.
Why Choose This Part
The module reduces BOM and development time by integrating the ESP32-C6 SoC and necessary RF components into a single shielded package. The U.FL external antenna connector provides flexibility to attach higher-gain or remotely mounted antennas for improved range or to meet installation constraints. Using a prequalified module simplifies mechanical integration and can accelerate certification work compared with a discretely routed RF design.
Applications
Key Specifications
Getting Started
Begin with Espressif's software stacks and examples: ESP-IDF is the primary SDK and Espressif also provides Arduino-core support and example projects for module-based designs. Use the module datasheet and reference PCB footprint from Espressif, and for RF testing attach a U.FL pigtail and a known-good antenna. Flashing and debugging can be done with standard USB-to-UART adapters and Espressif's flash tools or IDE plugins.
