Shake it, tilt it, or tap it—this AX22-sized board puts a cylindrical roll-ball vibration switch on a compact 22 × 22 mm PCB so your project can sense motion without MEMS sensors or ADC maths. Inside the sealed metal can a loose steel ball shorts two electrodes whenever the board is jostled (roughly ±15 ° from level or any sharp knock). An on-board 10 kΩ pull-up and 0.1 µF RC filter with a series 100Ω resistor, gives a microcontroller a debounced, logic-level pulse that’s readable on a single GPIO pin. Drop it into any AX22 backplane and you’ve added wake-on-shake, knock detection, or simple orientation sensing in one shot—whether you’re coding in the Arduino IDE, MicroPython, or MicroBlocks.
