Power to all the board parts are connected through five cut-straps with 50-mil holes, and marked
in silkscreen. These are intended for current measurement purposes. Do not leave these
unconnected as the MCU, sensors, or other connected circuitry might get powered through
the I/Os.Figure 3-2. Cut-Straps
Warning: Before doing any
hardware modifications, make sure the board is disconnected from USB, battery or
external power.
To measure power on the desired net, cut the cut-strap and connect an ammeter to the
50-mill holes.
