Auto Botix CJMCU-TRRS 3.5mm Jack AV Stereo Module
The Auto Botix CJMCU-TRRS 3.5mm Jack AV Stereo Module is a compact and reliable breakout board designed to easily interface devices that use a 3.5mm TRRS (Tip-Ring-Ring-Sleeve) audio connector with your electronics projects. This module allows hobbyists, engineers, and students to conveniently connect audio signals such as stereo audio, microphone input, and ground to microcontrollers, development boards, and DIY circuits.
Built on the popular CJMCU breakout design, this module provides clearly labeled pins for each contact of the TRRS jack, making wiring simple and organized. It is ideal for projects involving audio input/output, headset interfaces, audio signal processing, and embedded electronics systems. The sturdy PCB construction ensures durability while maintaining a compact footprint suitable for breadboards and prototype setups.
This module is widely used in Arduino, Raspberry Pi, ESP32, and other microcontroller-based projects where a standard 3.5mm headset or audio cable needs to be integrated into the circuit. It simplifies development by eliminating the need for complex wiring directly to audio connectors.
Whether you are building DIY audio systems, voice-controlled devices, headphone interfaces, or signal monitoring circuits, the Auto Botix CJMCU-TRRS module provides a clean and efficient solution for connecting stereo audio and microphone signals.
