Assembly Guide for A498x stepper drivers

  Unpack the driver.

  Cut the pin strip in half, so you get 2x 8pins each

  Insert the two pin strips parallel into the

  female headers of the ramps board.

  Make sure the shorter side looks out on the top.

  Place the A498x PCB onto the strips.

  Make sure all pins match the corresponding holes.

  Important: When inserting the A498x PCB,

  make sure the silkscreen on the RAMPS PCB

  matches with the silkscreen of the A498x driver.

  Plugging it in or leaving it plugged in

  and powering the RAMPS up

  will kill the A498x driver when

  inserted the wrong way.

  Solder all 16 pins to the PCB

  Since Shapercube 2.1, the kit is delivered

  with Heatsinks.

  Find the heatsinks.

  Along with the heatsinks,

  there is a piece of special thermal conductive

  double-sided tape.

  Cut the tape in 4 pieces which match

  the flat surface of the heatsinks.

  On the tape pieces, remove the protective tape of

  one side then push it to the flat surface of heatsink.

  Note that the colour of the tape may differ.

  Remove the protective tape from the other side of

  the tape piece and push the heasink to the chip.

  Important: Make sure that the heatsink does

  not touch any other component.
