MAX7313 Evaluation Kit
The EV kit provides two options for powering the on-
board LEDs. Jumper JU5 connects the LEDs to the 5V
(typ) supply from the PC’s USB port or to an external
supply voltage connected to the VLED pad. When eval-
uating the EV kit with a user-supplied I
external supply must be used to power the on-board
LEDs. Table 6 lists the LED supply voltage options.

On-board
The EV kit provides jumpers JU10–JU13 to allow for the
use of the P12–P15 pins as input ports. The P0–P11
pins can be configured as inputs, but are only utilized
as outputs on the MAX7313 EV kit. To utilize the
P12–P15 pins as inputs, remove the shunts from
JU10–JU13 and connect the input signal to the left-
most pin of the jumper.
The EV kit circuit can also be reconfigured for evaluating
a 5V-rated relay by using jumper JU6. Remove the shunt
from jumper JU10 and connect the relay across jumper
JU6. The MAX7313 can sink up to 50mA on the output.
