Power Supply
The main power supply is provided through four pins of the General Purpose Connector:
•
Pins 3 and 4 for the + 5 V
•
Pins 1 and 2 for the ground (GND)
Pins 6, 21, and 24 are also the ground connection for the correct ground plane required for correct RF
functionality.
A 5 V
±
5% - 1.5 A power unit is required to supply the Wireless CPU
®
in order to avoid serious RF
malfunctions. However, the Wireless CPU
®
does not need a constant 1.5 A current at 5 V on this power
supply.
