Self power module
Advanced users only—voids the warranty. Depopulate R31 to
power the device using V+ and GND from J2 and J5. You can
connect sense lines to S+ and S- for sensing power supplies.

CAUTION: Voltage is not regulated. Applying the incorrect
voltage can cause fire and serious injury.

Current testing
Depopulating R31 allows a current probe to be inserted across P6
terminals. The current though P6/R31 powers the device only.
Other supporting circuitry is powered by a different trace.

Loopback jumper
Populating P8 with a loopback jumper causes serial transmissions
both from the device and from the USB to loopback.

DC barrel plug: 6-20 V Greater than 500 mA loads require a DC supply for correct
operation. Plug in the external power supply prior to the USB
connector to ensure that proper USB communications are not
interrupted.

Powering the board with J2 and J5 without R31 removed can cause shorts if the USB or barrel plug power are
connected. Applying too high a voltage destroys electronic circuitry in the device and other board components
and/or can cause injury.
