A left/right control with a center press can cover a surprising amount of a small interface: move between choices, adjust a value, then select it. This breakout exposes those actions without requiring a keypad.

The common C terminal connects to ground. With pull-ups enabled on the host GPIO inputs, moving left or right pulls output 1 or 2 low, while pressing pulls T low.

The wiring stays simple and the behavior stays in your firmware. A menu, a jog control or a display-mode selector can use the same physical input arrangement.

Key specifications:

• C common terminal

• T push output

• 1 left output

• 2 right output

• Use GPIO input pull-ups
