REFERENCE: MEASURING CURRENT ON B1010SP0-EVB-1

To measure the total current consumed by the CEL module, a precision digital multi-meter can be used in place of the VDD_BAT

jumper. This measures all of the current flowing to the module.

In order to measure the correct current, it is also necessary to temporarily remove the SPI_ENABLE jumper on the module. This

is because in SPI mode the module has a 47kΩ pull-down resistor that is pulled high. See the figure below for the location of the

VDD_BAT and SPI_ENABLE jumpers.

REFERENCE: BATTERY OPERATION

The Target board can be powered from a CR2032 3V Lithium Ion battery (not supplied). It should be fitted to the battery holder

with the positive (+) side upwards.

When the battery is in use, the BATT/USB jumper should be moved to the BATT position. The location of this jumper is shown in

the above figure.
