The new USB Tester Backback 2.0 brings many new features to the already very useful tool. We have worked hard over the recent months to bring most of the many requested features.
The USB Tester Backpack is an add-on for the USB Tester that makes it easy to monitor the current and voltage of any USB device. It attaches to the USB Tester and displays the readings directly on the device. The default mode shows a graph of current usage, with the button cycling through the different modes.
The OLED Backpack can also connect to a computer and using the Java app you can data log the resulting data. Which can be imported into Excel as a CSV.This OLED is small but readable in all light conditions, the display is easy to use over SPI using Adafruit’s SSD 1306 and GFX libraries.
