Chapter 3 Installation and Configuration

The S5U13U11 evaluation board incorporates jumpers and 0 ohm resistors which allow it to be used in a variety of
different configurations.

3.1 Configuration Jumpers

The S5U13U11 has 15 jumpers which configure various board settings. The jumper positions for each function are
shown below. JP5, JP6, JP7, JP8, JP9, JP10, JP11, JP14 and JP15 are solder bridges to reduce power noise. To
change the jumper position remove the solder.

JP1 - Current Measurement of the S5U13U11 Evaluation Board
JP1 can be used to measure the current consumption of the S5U13U11 power supply.
When the jumper is at position 1-2, normal operation is selected.
When no jumper is installed, the current consumption for power supply can be measured by connecting an ammeter
between pins 1 and 2 of the jumper.
