2.3 Electrical Specifications

CQ7-D59 board needs to be supplied with an external 24VDC ± 5% power supply. All the other voltages necessary for the working of the board and of the connected

peripherals are derived from the main V

Power Connector is a Micro-Fit Right-Angle header, type Molex p/n 43045-0400, or equivalent, with the pinout indicated in the following table.

When choosing the power supply for CQ7-D59 board, please consider well what is the typical scenario for using the board (i.e., which peripherals will be connected).

Internal power section is able to supply a maximum of 3A @ 12V, 11A @ 5V and 6A @ 3.3V for Qseven module and for the external devices supplied directly by the

carrier board (i.e. USB devices, optionally SSD or SATA disks, display, etc).

It is very important to balance well the typical final configuration, summing all possible power consumptions of devices attached to carrier board.

This way it is possible to choose a PSU capable to supply enough current for the whole system.

The batteries should only be replaced with devices of the same type. Always check the orientation before inserting and make sure that they are aligned correctly and

are not damaged or leaking.

Never allow the batteries to become short-circuited during handling.

CAUTION: handling batteries incorrectly or replacing with not-approved devices may present a risk of fire or explosion.

Batteries supplied with CQ7-D59 board are compliant to requirements of European Directive 2006/66/EC regarding batteries and accumulators. When putting out

of order CQ7-D59 board, remove the batteries from the board in order to collect and dispose them according to the requirement of the same European Directive

above mentioned. Even when replacing the batteries, the disposal has to be made according to these requirements.
