HW-738 V0.2 Vibration Motor Module with LED Indicator & Pin Headers
The HW-738 (Version V0.2) is a compact vibration motor module built on a black PCB with clear white silkscreen labeling, including the Chinese characters “震动马达” (“Vibration Motor”) printed across the corners of the board.
The module comes pre-fitted with a round, coin/pancake-style vibration motor, pre-soldered to the board with red and blue lead wires for reliable connection. An onboard SMD indicator LED provides visual status feedback, while the reverse side of the board carries the drive circuitry.
