5.5. Current measurement
Current measurement of Microcontroller is possible, excluding the current consumed but
other circuitry around the board.
By connecting a current-meter between the TP3-TP4 and setting JP2 to open, it is
possible to measure the current of the microcomputer (other than BLE). By connecting a
current-meter between the TP7-TP8 and setting JP3 to open, it is possible to measure
the current of the microcomputer (BLE only).
Operate Microcontroller on its operating unit and power it from a USB or VCC-IN
terminal.
At 3.5EH (Energy Harvest) Power Operating Mode, Current consumption cannot be
evaluated correctly.
