-All of the tested development kits used standard configuration of iMX6 TinyRex Base Board with extended temperature range (-20°C to +85°C). The majority of tested kits used a standard heatsink. This heatsink sized 35x35x10mm is included in every development kit package. Thus these measurements show the actual performance of web shop based configuration. Some of the boards were mounted into a custom build [https://www.voipac.com/#iMX6-ALC-00000000 iMX6 TinyRex aluminium case].

 Test description: As mentioned above, different heatsinks and enclosures were utilized in order to compare the cooling abilities. All these tests were performed with Max version which generate the most heat by itself. All setup reached temperature +85°C in the chamber while still successfully running.

 === Enabling sharing ===
 iMX6 TinyRex Development kits and the control PC are connected via Gigabit Ethernet switch. To ensure correct IP address assignment, turn on the PC first, connect it with the switch and only after that turn the switch on. To be able to download the files from the FTP server, sharing option need to be enabled first. This can be done by setting up the network as a ''work network''. Sharing can be enabled in Control Panel -> Network and Internet -> Network and Sharing Center -> Click to Choose homegroup and sharing options:<br />
