{"title":"Adafruit NeoKey Trinkey - USB NeoPixel Mechanical Key Switch","handle":"adafruit-neokey-trinkey-usb-neopixel-mechanical-key-switch","url":"/products/adafruit-neokey-trinkey-usb-neopixel-mechanical-key-switch","description":"The Adafruit NeoKey Trinkey is a USB-A development board that combines an ATSAMD21 microcontroller, a Cherry MX-compatible key switch footprint, and an RGB NeoPixel LED into one tiny plug-in package. Insert it into any USB-A port and you've got a single-key macro pad, password entry device, or custom shortcut button — fully programmable with CircuitPython or Arduino.\n\nThe board includes a reverse-mount NeoPixel for colourful backlighting through the keycap, a capacitive touch pad for an extra input, and native USB support for serial, MIDI, and HID (keyboard/mouse) modes. Small, durable, and inexpensive — perfect as a first microcontroller project or a quick utility tool.\n\nKey Features\n\n\nATSAMD21E18 – 48 MHz Cortex M0+, 256 KB Flash, 32 KB RAM\n\nCherry MX-Compatible Footprint – Solder in your favourite mechanical switch (two solder points)\n\nReverse-Mount NeoPixel – RGB LED shines up through the keycap\n\nCapacitive Touch Pad – Additional touch input\n\nNative USB – Serial, MIDI, HID (keyboard/mouse), and small disk drive\n\nUSB-A Form Factor – Plugs directly into any USB-A port\n\nCircuitPython & Arduino – Fully supported with existing libraries\n\nReset Button – For restarting code or entering bootloader mode\n\n\nIdeal For\n\nSingle-key macro pads and shortcut buttons\nPassword entry devices\nCustom Escape key for MacBooks\nUSB MIDI triggers with visual feedback\nKeychain-friendly gadgets\n\n\nPackage Contents\n\n1× Adafruit NeoKey Trinkey PCB\n\n\n\nNote: Key switch and keycap are not included — solder in any MX-compatible switch. The board has a centre-nub hole only; if your switch has two mini side nubs, they will need to be clipped off.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2965,"title":"Default Title","sku":"AF-5020","price":13.55,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":2,"option1":"Default Title"}]}
