Buttons & switches

Most parts here are simple contacts: press or release, open or closed. A few outliers — rotary switch potentiometer breakouts, NeoPixel potentiometers, wiper plungers — carry separate wiring requirements worth checking before you order.

Keypads

Matrix keypads, analog ADKey boards, I2C keypad controllers, joysticks, and finished USB-HID keyboards are all here. Pin budget and simultaneous-press requirements are the splits that matter.

Touch

MPR121, CAP1188, CAP1203 Qwiic slider and AT42QT breakouts are sensor ICs for electrodes you wire yourself. Simple single-pad modules like the TTP223B give you one digital output with no bus required.
