Unboxing and Setup Cables - Apalis Evaluation Board with Heatsink

 
 

Overview

In this first lesson you will go through the process of unboxing your computer on module and carrier board and assembling the hardware.

A block diagram of the system setup and its connections is presented below for reference.

Apalis Heatsink

Step 1

Remove the Evaluation Board and the Apalis Computer on Module from the blisters. Insert the computer on module into the X1 connector of the Evaluation Board as tight as possible, with the module inclined ~30 to 45 degree in relation to the carrier board.

Warning: Make sure that the computer on module is well connected to the board. The image below have some checkpoints highlighted.

Step 2

Remove the protection from the Apalis Heatsink rubber that couples the module's SoC and the Heatsink itself.

Attach the Apalis Heatsink to the Ixora Carrier Board, on top of the Apalis computer on module. Use screws to guarantee that the thermal coupling is good.

Step 3

Connect a DVI-D monitor to X11 and an Ethernet cable to X12 of the Evaluation Board. Also connect a USB keyboard to X54, a 12V power supply to the barrel jack X17 or use a 7-27 V power supply to X15. Finally, plug the USB B type to USB A type cable to the X29. Make sure that the X39 and X40 jumpers are short circuited in the DVI position, i.e. middle pins.

Attention: Double check that your power supply is within the Evaluation Board limits (7-27V to X15 connector or 12V to X17 connector) and that the polarity is not inverted. Also, make sure that the current capability of the power supply is enough, or the system will shutdown unexpectedly sometimes. For evaluation purposes, a 12V 2A power supply is recommended.

Make sure that the jumpers JP10 and JP12 are setup to USB mode as the image below, once we will use UART-1 via the USB Type B connector X29.
