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.
The following table lists the items required:
|List of items required|
|USB Micro-A to Type-A (USB Micro-AB receptacle to Type-A) cable|
|USB keyboard and mouse|
|2.4GHz SMA antenna|
|SMA to U.FL cable|
Remove the Aster Carrier Board and the Colibri Computer on Module from the blisters.
Unpack the SMA antenna and the SMA to U.FL cable.
Connect the SMA antenna to the SMA to U.FL cable as shown in the picture below:
Connect the antenna to the U.FL connector on the Colibri iMX6ULL module as following:
Insert the computer on module into the X1 connector of the Aster Carrier Board on the bottom side, as tight as possible, with the module inclined ~30 to 45 degree in relation to the carrier board.
Warning: Make sure that the module is well connected to the board. The image below has some checkpoints highlighted.
There are two ways to power the Aster carrier board: a standard 3.5mm power jack barrel connector using a external DC power supply and a USB micro B connector, connector X4. In this guide, we will power the board via the micro USB connector, therefore it is necessary to close the jumper JP1 as shown in the image.
Attention: The total power consumption of the system depends on the module/peripheral/accessories used. Please note that power available via the micro USB connector may not be sufficient for modules or applications with high power requirements, since this configuration is not fully USB compliant. In such cases, it is recommended to use an external power supply to power the system. While using an external power supply, please remove the shunt jumper (if any) from the USB Power Jumper (JP1) in order to avoid short-circuiting the USB and external power supplies.
Attention: If you decide to power on the board from USB, make sure that you use a high quality and short cable. Long cables are known for making the Aster reboot intermittently due to voltage drop on the cable.
Connect the Ethernet cable to the X8. Note: Ethernet network must provide DHCP and Internet to the module.
Connect a USB micro-B to USB Type-A cable to X4.
Notice that the micro USB connector (X4) can be employed as a means to power the system and also has an integrated USB-serial converter that provides access to the computer on module debug serial port.
