Figure 68: Bottom Side of Heat Sink For every type of Toradex Apalis module, an optimized heats sink is available. The heat sink can be used as passive or active cooling solution. Passive means that the natural convection is used to transport the heat from the surface to the air.
At both edges of the module, ten test pads are available. These pads are used by the module manufacturer for test purposes. Page | 74 Toradex AG l Altsagenstrasse 5 l 6048 Horw l Switzerland l +41 41 500 48 00 l www.toradex.com info@toradex.com...
The reason is that the Apalis module standard does not combine power supply pins to large pads. In addition, the pin numbering is different. Page | 75 Toradex AG l Altsagenstrasse 5 l 6048 Horw l Switzerland l +41 41 500 48 00 l www.toradex.com info@toradex.com...
