Warning: If you use this with a quickcharge charger that most cell phones are using these days, please cut the solder jumper located on the bottom side of the OLED Backpack. Failure to do so will risk damaging the backpack due to an over-voltage condition. These quick chargers are able to go over 5V. There is no protection on the USB Tester OLED Backpack.

The USB Tester is inserted inline between your USB device and your power source or computer. This allows you to make sure you are getting a true 5V source and to monitor how much power your project\device is using without having to splice open a USB cable. For example, you can check which charger/cable allows your phone to charge the fastest. Or help figure out what size battery you need for that Arduino project on your workbench. The base can be used with a Digital Multi Meter or with the OLED Backpack. The backpack allows you to see the readout directly on the display without hooking up a multimeter. The default mode shows a graph of current usage, with the button cycling through the different display modes.

The OLED Backpack can connect to a computer either using the Java app or the wizkers.io Chrome app. Both can graph and log the data which can be exported as a CSV file. Wizkers is easier to setup and can handle firmware updates.

Very nice and practical little unit

The bundle was easy to assemble and works perfectly for monitoring the power consumption of my RGB LED light during the prototyping phase.
The different display modes are very useful as well:

Very nifty little gadget

I really like the fact that the USB Tester has the little OLD display. It gives more information than just seeing the current current consumption, The USB Tester worked perfectly for a bug I was investigating (current draw increased by 8mA when turning on the DMA clocks). It just worked. Plug everything together and awy you go. Its a keeper.

Nice product

This works great for testing USB charging. The only issue I've seen is that it adds enough resistance to the power lines to cause my Galaxy S4 to not go to full 1.9A mode. The UI is great and it works very well otherwise.

Response from FriedCircuits | Jan. 19, 2015

Thank you. I have been increasing trace width to help with that. But the thing that helps the most is to get the shortest USB cable you can. We sell 3ft cables but I thinking maybe I should stock some 1ft cables. If yours shows the firmware version on boot up you have the latest. Otherwise check http://friedcircuits.us/docs to update to the latest.

Works great!

Just receive mine. It's really nice bit of kit. Of course you can buy similar on ebay from China but most of them are garbage. Build quality and the display in this one are great. Soon I would like to check its accuracy, hope it will be ok.

Response from FriedCircuits | Nov. 18, 2014

Thanks. Yours also has the latest firmware with the new bar graphs and cleaned up interface. The measurements are done by the Ti INA219B. Should be a link to the datasheet in the product listing of the backpack.

Great updates for USB Tester 2.0 Bundle

Pro's:
I really like that the display function button was moved to top side - I have the previous 1.0 & it kind of stinked to squeeze my fat finger between the 2 PCB's to switch between screens
Nice updated firmware
Nice 2nd VA tester for non-USB devices

Con's:
Instructions/detailed description/User guide not easy to locate on developers website - when the entire bundle ships, a printed user guide would be beneficial or at least the web links on the invoice
Tx/Rx on top level bundel - appears to be for serial comm. but not sure is it for serial input/output or for voltage measurement only, USB VA tester version would be super nice if had a 9 pin RS232 & a additional 6 pin I2C communication interface (SCL/SDA/CHG/Reset/VDD/GND) was incorporated, maybe switching over to the Atmel 64pin AT90USB1287 could help accomplish this

Unbelievably Useful (Cute too)

I had been using a clunkier big brother competitor to this prior to finding this little beauty. What sold me was the ability to read the voltage of D+/D-. This feature is incredibly useful to determine what charger configuration you're device is plugged into so you know whether it's pulling as much current as it should. The OLED display is gorgeous and packed with relevant info. I'll definitely be picking up a few more of these guys in the near future.

Response from FriedCircuits | Feb. 26, 2014

Thank you for the review. I am happy that you find the D-\D+ feature useful. I haven't had a chance to investigate it and see how I can provide more feedback to the display based on the voltages of the D-\+ signals. I am getting a new batch ready soon.
