Add test points #12

Closed jcoffland closed 9 years ago

jcoffland commented 9 years ago

It would be a good idea to add a few test points. They should give us access to ground and all the regulated power sources. Plus we might want to be able to test the clock signals to the motor drivers and AVR. There may be other good places for test points as well. This will make debugging the hardware much easier.

The test points themselves could simply be plated through holes which we could later populate with a single pin header if needed. They should be big enough to accept a pin from a standard 0.1" spaced pin header.

Test points added to schematic on spi lines each power bus, and all lines for control of motor 1. Will close after layout is complete.

These will be a big help.
