What is this TRS bit? Turtle Rock Studios? Transmission Raman Spectroscopy? Not quite, more like Tip-Ring-Sleeve.
This nifty, gold-plated connector is known by many names, phone plug, phone jack, headphone jack, jack plug, etc. Used to transmit stereo audio signals, these connectors are a mainstay in audio equipment, especially speakers and microphones. For audio, tip is left channel, and ring is right channel, and the sleeve is ground.
Each jack comes with a slim, gold-plated body with three contacts to solder to and a panel mounting hex-nut.
TRS jack connectors don’t have to be used only for audio! They make great general-purpose connectors where you need 2 or 3 signals and cheap, common cables. For example, in accessibility tech, these are often used to connect buttons or low voltage actuators.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
