The USB Power Gauge comes in kit form so that you can customize it to your needs. There are only 3 parts to the kit and basic assembly takes just a few minutes.
Assembling the USB Power Gauge is pretty simple. Just solder the male and female USB connectors on either end.
With a connector on each end, your gauge is ready for use. Proceed to the next page for usage instructions, or read-on for other assembly options.
Optionally, the USB Power Gauge can also be spliced right into a cable for a more compact package without all the connectors.
Serial Data Monitoring
For real-time monitoring of voltage, current and wattage over a serial link, you can connect an FTDI cable, FTDI Friend or even an XBee using the breakout holes on the side of the power meter board. Connect at 9600 Baud - data will be spit out automatically!
