B.4 Power to Peripheral Cards
DCIN and Vcc are available on friction-lock connector terminals J7 and J8 to power
peripheral cards that may be used with the Coyote.
Keep in mind that the Coyote draws 377 mA from the Vcc supply, and that the diode at D1
(shown in Figure B-1) can handle at most 1 A at V
capacity to be shared among the DCIN and Vcc pins on friction-lock connector terminals
J7 and J8. Table B-1 lists the available current at DCIN based on the current drawn at Vcc.
