The board is to be wired this way
On the left side, you have the main power supply for the fans
You will need to connect your +12V from the ramps
WARNING: make sure to to respect the polarity:
Red wire = +12V
BLack wire = 0V (GND)
You then need to connect this board to the Servo port of the ramps.
Here a reseveral pictures to help you
The blue arraow shows where you can get the +12V power supply from the board
The black arrow shows where to connect your fans.

Pins D6 and D11 are used to drive the board (here on the red row).
These 2 pins are PWM capable output pins.
Keep calm, everything is fine!
Shift the module 2 columns on the right
In your firmware, just change the pins mapping (file pins_ramps.h for marlin firmware)
Of here it's still feasable!
Shift right your RRD by 2 pins, the same way as describe above.
Here is a firmware already modified: Scalar S + E3D Chimera + RRD + Z M8 + TMC2208 in X et Y + dual end of filament module
The procedure to install the firmware Is described here
In your firmware you need to update the pin association (file pins_ramps.h inside marlin folder)
Look for line "#ifndef FIL_RUNOUT_PIN"
Warning: this setup requires:
No customer reviews for the moment.
