Features:

• The PCB has a built-in selection terminal for stepper motor drivers running in SPI mode, and also is compatible with STEP/ DIR and SPI modes.
• The connectors of  the power and heat bed now using the 30A high current terminals, which effectively can avoid the burning terminal problems.
• Now, the wiring would be easier due to clear identification of the pin out with its new top and bottom overlays.
• Added the external reset pin interface. It is convenient for users to extend
  the reset button.
• X, Y, Z, E0, E1 all of the axis now use parallel dual motor interface, so that the board can be used to build a machine that require more stepper motors than its earlier version.
• Using a combination of color pin and row connector, provides visual feedback and distinguishing each function interface which looks beautiful and practical.

Selection between SPI and STEP-DIR driving modes:

• When using driver SPI model : connect 1 and 11,2 and 12, 3 and 5 ,4 and 6 respectively, using four pcs 13 (short circuit caps)
• SPI is the serial bus mode of operation, where 1 connection 11 is MOSI, 2 connection 12 is SCK, 3 connection 5 is CSN, and 4 connection 6 is MISO; ( Corresponding picture indication)
• STEP/DIR (stepper/ directional drive mode):Figure 11, 12 and 5 respectively represent MS1, MS2 and MS3 of STEP/DIR mode (subdivided selection end),8, 9 and 10 are all VCC (high level);Take the LV8729 driver as an example. Connect 5 (MS3) and 8 (high level) by using a 13 (short-circuit cap),The driver works in STEP/DIR mode and it is 16 subdivisions.
• Note:The interpolation of MS1, MS2, MS3 and 8, 9, 10 in STEP/DIR mode is selected according to different subdivisions of different drivers.

Package Includes:

• 1 x BIGTREETECH RAMPS 1.6 Plus R6+ 3D Printer Controller Board
