PWM fan connector
   

4-Pin 1.0 pitch white connector

  • Yellow (FG)
 

  • Black (Ground)

 
  •  Blue (PWM)
 
  •  Red (+5V power)
Jumper setting for CAM/DISP1
   

  • If either CAM/DISP 1 is used then both jumpers must be fitted to route the I2C bus to the connectors.
 
 
 
 
12-pin configurable  header (J2)
   

  • Pin1-2: nRPIBOOT - if fitted, forces USB booting (useful if the eMMC becomes corrupted)
 

  • Pin3-4: EEPROM_nWP - if fitted, write-protects the EEPROM on CM5.
 

  • Pin6: SYNC_OUT - IEEE1588 timing pin. (can be configured as input).

  • Pin8: USBOTG
 
  • Pin10: PMIC_ENABLE
 
  • Pin12: Connect a push button to wakeup or shutdown CM5.
 
  •  Pin1, 3, 5, 7, 9, 11: Ground

Installing the Raspberry Pi Compute Module 5
Step 1 Protecting from ESD
 

Grounding protects the components from the static electricity that can be naturally present (electrostatic discharge, ESD).

 

  • Notice: Risk of damage to the equipment due to electrostatic discharge. Always: Touch the working surface before touching electronics.
 

  • Ideally: Use ESD protective equipment, such as ESD table mats and grounding cords.
Step 2 Aligh the IO board and CM5
   

  • Place the board in front of you, the connectors facing to the top.
 

  • Orient the CM5 as indicated by the arrow.
 

  • Use the outline of the chips to help find the correct orientation of the CM5.

 

  • Carefully place the CM5 without force.
 

  • The CM5 should fall into place slightly when correctly aligned.
 
  • Confirm the Compute Module is correctly mated by looking at each corner of the IO Board.
Step 3 Installing the CM5
   

  • Press the CM5 board onto the board-to-board connectors until it clicks into place.
 

Make sure you press on both sides (the two long edges).
 

  • This requires quite a bit of force. If you don't hear a loud click, it is most likely not fully seated.

  • Do a visual check to make sure the CM5 is installed correctly: it needs to run parallel to the IO board.
Step 4 Installing the heat sink (requires separate Raspberry Pi CM5 cooler)
 

  • Please remove the protective white paper from the thermal silicone.
 

  • Place the Cooler onto Compute Module 5.
 

  • Align the mounting holes, insert four M2.5 × 8 screws (supplied) upwards from beneath the IO Board, and tighten.

   
Step 5 Installing the RTC battery
 

  • Insert the CR2032 coin-cell  battery (making sure that the battery isoriented correctly. Positive side (+) UP).

 
 
 
 
Step 6a Installing the M.2 2280 NVMe SSD devices
 

  • Insert the M.2 SSD into M.2 slot then slide the SSD drive into the M.2 slot at 30 degrees while pushing it gently till it fits into the slot. 
 

  • Notice that after insertion into the M.2 slot, the SSD drive inclined angle to the board. 
 

  • Press the M.2 SSD drive till it sits on the riser screw then lock it in place using the M2 mounting screw.

Step 6b Installing the M.2 2230/2242 NVMe SSD devices
 

  • Set the the M.2 extension board on top of the spacers, and use the two M2 screws to secure it in place.

  • Installing the 2230/2242 SSD follows the same process as installing the 2280 SSD, as outlined in Step 5a.
