Last month we released the USB Tester for measuring voltage and current of your USB project and devices. This tool made it easier to connect your digital multi-meter for measurement. You can read the full product description here: /2012/12/our-first-product-usb-tester/. This month we are working on releasing a OLED Adapter backpack. This will allow you to view the voltage and current without the need for a DMM.
I recently released the first feature here: /usb-tester-oled-backpack-surprise-feature-1/.Today I wanted to announce another feature that the OLED Backpack will have.
During development I came up with the idea to add a threshold warning LED. The threshold value is set using the desktop Java application. Once the current reaches the threshold value the LED will stay on until it falls below. I think this will be a helpful feature when prototyping projects, especially if you are trying to reduce power consumption and you want to test different code functions.
