Review on Uxcell Common Segment Display Digital Tools & Equipment : Garage & Shop by Jeff Islam
Great product but needs to come with spec
This 7 segment display works great after I figured out how it works. I couldn't find a datasheet for it online, and the image provided only shows which pins are which. With the specs posted on Revain it seems you can run this at 5V, but I had to use 9V with 470 ohm resistors for each segment. I suppose after troubleshooting I'd say that each LED is listed as having an average forward voltage of 2V, but that wasn't obvious to me. This might be obvious to a more experienced person, but now I can share my insights with everyone.
