Voron V2 - BTT SKR 2 Wiring for both SPI and UART modes

What is the difference between UART mode and SPI mode?

  • This stuff refers to the way the hardware communicates.

  • So, how do you know which mode to pick? It depends on the stepper motor drivers you choose to buy with the SKR 2 boards.

  • The list below shows which stepper motor drivers are UART mode and which are SPI mode.

  • In the list below, locate the name of the stepper motor drivers that were purchased with the boards and click on their name.
