⏳ This item is currently sold out — a new batch is on its way and will be available soon!

This AX22-sized module integrates the LD0825BC linear resonant actuator (LRA) with a DA7820 haptic driver on a compact 22 × 22 mm PCB. The DA7820 is designed for LRAs and automatically handles resonance tracking at 240 Hz, ensuring strong and consistent tactile feedback with minimal code. It drives the motor with a 1.2 Vrms AC signal and up to 90 mA while protecting it with kick-start and braking control. The module also includes Stemma QT connectors for quick I²C integration and chainable connections. Works with  Arduino IDE, MicroPython, or MicroBlocks.
