This AX22-sized board seats a KOTL flat eccentric-rotating-mass (ERM) motor on a 22 × 22 mm PCB and adds a low-R<sub>DS(on)</sub> MOSFET driver, so you can trigger crisp haptic feedback with a single active-high GPIO pin—no H-bridge or PWM timer required. A fly-back diode and bulk capacitor tame startup surges, while the driver lets even 1.8 V logic pull the 90 mA load safely. Snap it into any AX22 backplane to give wearables, control panels, or notification gadgets a silent buzz or rhythmic pulse in just a few lines of code—Arduino, MicroPython, or MicroBlocks.

Arduino Example Code

example.ino 
// Constants
const int motorPin = 15;  // Pin connected to the vibration motor

// Variables
bool motorState = false;  // Motor state: true = ON, false = OFF

void setup() {
  // Initialize the motor pin as an output:
  pinMode(motorPin, OUTPUT);
}

void loop() {

  // Set the motor pin to the new state
  digitalWrite(motorPin, HIGH);
  delay(100);
  digitalWrite(motorPin, LOW);
  delay(1000);
