Questions: Alternate TMC driver setup

[flackenstein]

Worth adding it's a lot easier to procure the Trinamic SilentStepStick in the Americas and it has a unit cost that isn't that much more than the IC itself, and makes for easier repairs/upgrade.

There are a few downsides to having a stepstick/modular solution:

1. Thermals is a lot worse. When mounting the driver directly to the board the whole board acts as a heatsink
2. Cost and complexity of a modular approach is higher.
3. Connectors use up a lot of precious board space. As you say some can be mitigated by the ability to put components under the module.

For now I think the better solution is to have the driver directly mounted to the main board.
