Use and settings
Connects the either “BUCK-A”, BUCK-B” or “BUCK-C” converter output to
the battery terminals (through shunt resistor network).
The jumpers should be mounted in pairs due to potentially high currents.
Never place the jumpers so that the output from the different buck
converters are shorted, this may damage the buck converters.

4.7 Micro switches and LEDs
A number of LEDs and microswitches are placed in the same end of the board as the
ATmega644 board controller. These are connected to the ATmega644. The LEDs
and switches on the left side can be used for general IO, and the LEDs in the right
side can be used e.g. for displaying battery charge voltage and currents.
4.8 Test points
Test points are placed on all relevant lines of the buck converter circuits. GND/PGND
test points are placed together with the line test points to get accurate measurements
of the analog signals.
