Power Supply to External Devices via Socket P1A
The phyCORE Development Board LD 5V can be populated by
additional components that provide a supply voltage of 5 V at pin 6 of
DB-9 socket P1A. This allows for easy and secure supply of external
devices connected to P1A. This power supply option especially
supports connectivity to analog and digital modems. Such modem
devices enable global communication of the phyCORE-P8xC51Mx2
over the Internet or a direct dial connection.
On all PHYTEC Rapid Development Kits mounted with a phyCORE
module featuring a Philips microcontroller, these optional
components are already populated at U11 and U12 at time of delivery.
The following figure shows the location of these components on the
Development Board:
