1.4. Red Pitaya Aluminium Case Assembly

Regardless of whether you bought your Red Pitaya aluminium case in a kit or as a separate add-on, you will need to manually assemble it.

1.4.1. Components


Components of the Red Pitaya Aluminium Case.

  • 4 screws that close the housing and hold the board

  • 4 rubber feet for secure positioning on the desk

  • a thermal pad (just barely seen in the photo)

  • a transparent plastic rod that guides the light of a red LED (Ready/CPU activity) to the top of the casing


Interior of the Red Pitaya Aluminium Case.

On the interior, there is a block located in the upper part of the housing (right) that passes the heat to the housing. Therefore, the entire case acts as a heat sink.

On the lower part, there are fits for a few air vents (left).

Apertures in the case expose connections to the expansion ports E1 and E2.


1.4.2. Assembly Instructions

  1. Remove the small plastic feet by pressing the clips at the top with a small pair of pliers and pushing the feet down.

  2. Repeat the procedure for STEMlab 125-14 with the heat sink by pressing the clips together on the bottom and pushing the holder gently up.

  3. The heat sink of the STEMlab 125-10 is bonded with the FPGA. Slightly turn the heat sink, as shown in the picture below, until it comes loose.

  4. Remove the remainder of the thermal paste.

  5. Apply the thermal pad to the CPU.

  6. Place the Red Pitaya board into the bottom part of the casing.

  7. Turn the top part of the casing upside down and place the light-guiding plastic.

  8. Close it up with the bottom part of the casing, including the Red Pitaya board. Make sure that the holes from the board and the casing are aligned.
