Current Measurement Jumper
To measure the PSoC 4200M power consumption, a header is populated in series with the power supply to the PSoC
4200M, which can be used to measure current using an ammeter without the need to de-solder any components from the
board (marked
17
in
Figure A-15)
.
Figure A-18. Schematics of Current Measurement Jumper
The following two methods are supported for measuring the current consumption of the PSoC 4200M device.
When the board is powered through the USB Mini-B connector (J6), remove jumper J14 and connect an ammeter
between terminals 3 and 4, as shown in
Figure A-19
.
Figure A-19. Current Measurement When Powered From USB Connector
When the PSoC 4 M-Series Pioneer Kit is powered from an external voltage supply, remove the USB cable from J6.
Connect the positive terminal of the external voltage supply to the positive terminal of the ammeter and the negative
terminal of the ammeter to pin 4 of J14. Connect the negative terminal of the external voltage supply to and GND pin
on the board.
Figure A-20
shows the required connections.
