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.ROTA
, board.ROTB
, and, if applicable, the push button is board.SWITCH
.
The rotary encoder is available in Arduino as PIN_ENCODER_A
, PIN_ENCODER_B
, and, if applicable, the push button is PIN_ENCODER_SWITCH
.
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 PIN_TOUCH
.
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 PIN_NEOPIXEL
.
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).
