So many new motor controllers but no new relays?

Are there any data sheets available for the SD540 controller? With all those pins it must have more than just pwm communication. Some dimensional info would be great too.

Those are heatsinks actually. And I'm a bit worried by their proximity to that 3D printed mount though.

Are you sure those pins on the front of the case are heatsinks? They look like header pins to me.

Oh my bad
I believe that is a port for a ribbon cable, which they also sell. Not sure about the protocol used though, so I can't tell if more than PWM is possible.

"Power gap" or not, there is still an embarrassment of riches when it comes to motor selection in FRC.

Please say that again, I remember the days of window seat, window glass and FP motors...

We are not a rich team and have invested in a variety of Banebots transmissions. It would be a huge waste of our funds and I imagine other teams funds to have to replace these transmissions.

Does anyone know how to interface an AndyMark 9015 motor with a P60 transmission?

Yup! Here you go: http://www.andymark.com/product-p/am-2890.htm

Both the AM 9015 and the BB 550 are RS-500 style motors so they should have the same mounting features and shaft size. As long as you can get the correct pinion gear on the 9015 it should work.

Per this post by NI, the brownout info in the NI RoboRio User Manual is incorrect, and the WPILib documentation should be considered authoritative.

Using this kit with an AndyMark 9015 motor requires some care, because that motor has a knurled shaft. Refer to the layout drawing provided on the AM site; measurement over the knurls is larger than the pinion bore by 0.002 inch at the tolerance limits. Be careful to keep the shaft square to the pinion and to the tool you are using to press.

Also, the AM 9015 has a longer shaft than BB500. Not sure if there is enough clearance inside the P60 to accept that shaft without trimming; in any case the pinion will have to be pressed further so that the AM 9015 shaft protrudes, not simply flush with shaft as you would for the BB500.
