- The signal input connector seems like an odd choice, and it looks like the kind of thing that PWM cables could fall out of easily, and then, due to lack of labeling, get reconnected incorrectly.
- If you have a bank of controllers, and one of them dies, do you have to replace the whole bank?
- Would be nice if brake/coast could be changed on the fly (we used to do this with victors by connecting a PWM cable where the jumper would go).
Might get one of these to play around with it, but generally we avoid new, un-FRC-proven components the first year they're out (unless there are no alternatives like in 2014). |
To answer your questions:
The mounting screws are included when you purchase the SD540. Also, our case is 3D printed so there are multiple options in the works that do not call for a complete redesign. We plan to release casing options with different mounting options and through holes.
The connector is not only for PWM. Currently it allows for firmware updates, and in the future CAN, encoder connection, and possible I2C. Labels are on the bottom.
If a unit dies on one of the multi-bank options, you only need to replace that unit. A kit will be offered for just such a situation.
Brake/coast can be changed on the fly. There is a dip switch on the bottom that just needs to be flipped. You can also change direction.
