The DC Tester is a Voltage and Ampere breakout for measuring DC current from 0-26V at 3.2A Max, when used with the USB Tester. The DC jacks make it easy a wider variety of devices. You can easily put this in inline between your power supply and your project. Just like the USB Tester. Except now you can use this for any project that isn't USB powered. Then you can probe the voltage or current with your DMM (Digital Multi-Meter).
If you have an OLED Backpack, this will allow you to swap it out with the USB Tester, view the output on the display as well as data log it with the Java app (it will be updated for higher voltage). Due to the wide voltage ranges of the DC Tester, the OLED Backpack will need its own power source. It can be your computer, a phone charger or a USB Battery pack.
Depending on how you use it, you may need to do some soldering. The soldering is pretty easy to do. For an additional fee, we’re happy to solder for you, just be sure to select the option when ordering.
