How does it work?
The voltage across the integrated
2 milliohm (.002 ohms!)
, 0.1% shunt resistor is measured by the internal 16 bit ADC,
allowing for measurements over the impressive current range with a resolution of 1.5 mA. (The resistance of the
resistor is so low that some multimeters will register it as a short!)
In a high side configuration the bus voltage measurement and power calculation can be retrieved accurately, however
advanced hackers wanting to measure bus voltage in a low side configuration will need to cut the jumper connecting
V+ to VBUS and connect the VBUS pin to the voltage bus.
Comes as a fully assembled breakout board with a 5.08mm terminal block (extra chunky!) and header. Some light
soldering is required to attach the header and terminal block.
Note that when switching inductive loads, the instantaneous voltage levels may greatly exceed steady-state
levels due to inductive kickback. Chip damage can occur if you do not take precautions to protect against
inductive spikes.
