2.4.3 JR4, Connector P4, P8 Voltage Select
2.4.4 JR5, Connector P2, P10 Voltage Select
Jumper JR4 is a surface mount jumper located on the bottom side of the board. To
use a configuration a zero ohm resistor should be used for shorting. This jumper allows
the user to bring +5 or +3.3 volts to connector P4, pin1, and connector P8, pins 1 and 2.
When configuration A is used +5 volts is brought to the connectors. Configuration B
routes +3.3 volts to these connectors. These settings are shown below.
The layout of this jumper is shown in the figure below.
