Current Measurement Header
Current Measurement header
J109
can be used to measure the current consumed by the ATBTLC1000-
ZR110CA module using an ammeter. The two 0Ω resistors
R111
and
R112
can be removed to measure
the current consumed by individual power rails
VDDIO
and
VBAT
respectively by soldering in wires for an
ammeter.

Jumper Configuration on Pin headers
The ATBTLC1000 ZR Xplained Pro has few pin headers and jumpers to configure UART(with flow
control) or SPI interface with different pins on the extension header of the Xplained Pro MCU board. The
headers provided for this purpose are:
•
1x2 Pin headers (J101, J102, J103, J104) - 4
•
1x3 Pin headers (J105, J106, J107, J108) - 4
The pin headers and its functionality are mentioned in the table.
