William Garrido writes, “I released the USB Tester OLED Backpack today and thought it would be good for you guys to post up. It is an add on for the USB Tester for measuring voltage and current. With the OLED you don’t even need a DMM and can view the measurements on the OLED display and log them to your computer with the Java app.” In the above photo, the backpack is measuring voltage and current usage by a Raspberry Pi.

More details can be found in William’s post at Mobilewill. He is also seeking supporters for this project via a two-week fundraiser on Tindie. He says the source code will be available for download upon the project’s final release.

    I like the form factor : )

    I like the project, but I thought it was rather odd that it uses a prepackaged – and fairly expensive – display from Adafruit, rather than hosting the display itself. That’s got to add a fair chunk to the cost of the board.

      The reason I used the Adafruit OLED display is because it includes everything to run at 5V. They display needs a higher voltage and it would have to be a separate PCB for everything to fit. Also this wouldn’t be possible without her libraries so this gives back to Adafruit as well.

    The 0.96″ 128×64 OLED displays on ebay are pretty cheap, although they use a different controller and I’m not sure how to interface to it. Last year I tried a small 128×64 OLED module that had a I2C/SPI/Serial interface, which worked OK, but the seller “dig-ole” is no longer on ebay.
