The TK30 at an angle: a black board with a wide gold border, a flat round coin motor near the top with red and blue leads, a small transistor, a diode, a regulator and a few small parts, a small LED, lonely binary up the left edge, and a right-angle four-pin header labelled GND, VCC, NC and SIGNAL.3D

Vibration Motor

A 10 mm coin vibration motor on a TinkerBlock board, switched by a MOSFET and fed from the board's own 3.3 V regulator. SIGNAL HIGH buzzes, LOW stops, analogWrite sets the strength. VCC only feeds the regulator, so 5V on VCC is safe beside a 3.3 V board, and 3V3 or 5V both give the motor about 3.3 V.

3.0V rated, from its own regulator

Turn it over and see the three holes to wire: GND, VCC and SIGNAL. SIGNAL only switches a transistor; the motor runs from the board's own 3.3 V regulator, fed from VCC.

Point a phone camera at the code and this page opens there. It is the same address as the one printed on your box, so it is also what to show someone you are passing the board to.
