Old hard disk drives can make an awesome basis for electronic projects (POV propeller clock etc). The catch is that you can't just power up a HDD motor and expect it to spin... Hard disk drives use brushless DC (BLDC) motors which need special electronics to drive their coils.
You could, of course, try build your own brushless motor driver circuit - but that is a project and a half by itself. If you are anything like me you just want to get on with the flashing lights bit!
This compact module is a breakout board for the Philips TDA5144AT BLDC motor driver chip. Just connect it to your HDD motor and get on with the rest of your project.
The module works with motors that have 4 terminals (Y-Configuration), it does not work with 3 terminal (Delta-Configuration) motors. The Y-configuration is more common, but please check your intended HDD before ordering!
This is a fully assembled module. It measures approx 30mm x 14mm. Supplied with an un-soldered 7 way pin header.
Note: This module just drives the motor and is intended to let you use these useful motors in your own projects. You cannot use it to read/write data to a hard disk drive!!

I am an electronics hobbyist from Brighton UK. I love playing with microcontrollers and doing interesting things with MIDI and analog noiseboxes. Lots of new ideas in the pipeline so watch this space...
