II. Hardware overview
1. Power supply requirements
The RASPIVEND can be powered with stabilized 24VDC or 12VDC, depending on your
MDB PERIPHERALS and CCTALK Peripherals. You must use a stabilized DC power
supply with at least 2A output. It is necessary to follow the correct polarity. In the
eventuality of an accidental polarity reversal, the entire board, the MDB PERIPHERALS
and the CCTALK PERIPHERALS are protected, but will not work. The board also supplies
the 5V/2A for Raspberry PI (or compatible). The system eliminates the separate 5V
microUSB power supply for Raspberry PI. You will only need one power supply for the
entire system.
2. Connector description
-
<J17> –
POWER connector for the RASPIVEND and MDB PERIPHERALS. Use only
stabilized power supplies, with a voltage rating according to your MDB PERIPHERALS.
Also, be careful at the current rating, since this may vary from one MDB peripheral to
another. Use your MDB peripheral manual to identify the power needs.
