5.2.2. Current Measurement Header
Current Measurement header J101 can be used to measure the current consumed by the ATBTLC1000
module using an ammeter. The two 0Ω resistors R112 and R113 can be removed to measure the current
consumed by individual power rails VDDIO and VBAT respectively by soldering in wires for an ammeter.
5.2.3. Debug Connectors
Debug I

C (J104) and Extension port (J105) are not mounted on the board. Extension port J105 can be
configured as Debug UART or as SPI to connect to external sensors. Refer to the ATBTLC1000-
MR110CA datasheet for reference.
