Jeff I do not have a source for them but maybe we can find some surplus part that has them in it for cheap or something to toy with.

Here is a PCB layout for the TDA5144AT.
I will update later for 5145 and also add some mosfets.
Not sure how the mosfets will work though since the controllor is sensorless. This is just a start and I have not calculated the values for the capacitors yet but info is in the datasheets.
It is pretty much the same as for the 5145 but 5145 has more pins. Since this chip is discontinued I guess I can rack this up as good experience for drawing a PCB. In order to be a stand alone board I guess this thing needs some way of varying the motor voltage and a Voltage booster if it's used with a single lipoly

Maybe we can find another single chip controller.

Have Fun
