Adafruit 5954 TRRS Trinkey - USB Key
Adafruit 5954 TRRS Trinkey - USB Key is a compact, versatile USB key and TRRS breakout designed for Assistive Technology (AT) innovators. The Adafruit 5954 TRRS Trinkey is a cost-effective yet highly customizable AT device that connects to a USB A port and is ideal for creating switches or variable inputs through 3.5mm audio jacks. With six GPIO pins linked to a switched TRRS jack, users can detect plug insertions, configure pins as input, ground, or 3V power, and even support up to three switches or two analog potentiometers with a splitter. Powered by an ATSAMD21 microcontroller, it supports CircuitPython and Arduino for easy customization, enabling MIDI, serial, or HID keyboard/mouse functions. A NeoPixel LED and reset button add functionality, making it a flexible tool for hackers and creators.
