The Rotary Trinkey is simple but full of features. Time for a tour!
These are the through-hole pads for the rotary encoder. There are 5 small pads for the rotary encoder pins, and two larger pads for the tabs.
The rotary encoder is available in CircuitPython as
board.ROTB, and, if applicable, the push button is
The rotary encoder is available in Arduino as
PIN_ENCODER_B, and, if applicable, the push button is
On the end of the board, opposite the USB connector, is a capacitive touch pad.
This pad is usable in CircuitPython at
board.TOUCH, and in Arduino at
On the skinnier end of the board are the four pads that make up the USB connector. Plug directly into a USB A port to use the Rotary Trinkey.
On the back of the board, in the center towards the touch pad end, is a tiny RGB NeoPixel LED.
This LED is controllable in CircuitPython at
board.NEOPIXEL, and in Arduino at
The button on the back of the board is the Reset button.
Tap once to reset the board. Tap twice to enter the bootloader (needed for installing CircuitPython).
