1.2 Modifying the Curiosity Board to Obtain Accurate Power Measurements

Todo: Modify the Curiosity Nano board by cutting a trace and soldering two pins.

If the power is observed form the micro-USB port, the Power debugger will consume some power and make the readings inaccurate.

Figure 1-1. POWER Trace Location

There is a small trace labeled POWER on the Curiosity board. By using a sharp tool, cut the trace until the two holes are not in contact any more. Check this with a voltmeter.

After the trace has been cut, solder two pins in the holes. To program the board, the two pins have to be connected with a wire from now on.
