They are perfect for SC Transmitter meters, so small, they mount on the back of a 0.96 oled and don't take any room up

Thanks Phil for this little project. It works great.
Mine did not need any pullup-resistors.

here is a slight variation to Phil's simple tester,
using a128x64 oled, I've incorporated a rx battery level meter too.
Notice this Oled is the split screen yellow/blue version which works nicely on this one

I made one too! I added the pull up resistors "just in case". So simple yet so useful.

A great little device I must say :P

I also made one, it is a really useful design.

I found that if powered by a battery alone it would give erroneous readings if my hand was near the connector but adding a 10k pull down resistor cured that problem.

I chose to box mine with a cheap and cheerful servo tester. The PWM meter is on its flying lead still so I can monitor either a receiver or the tester output.

Ade, I like it! I have the same cheap & cheerful server test - gotta love that Engrish :lol: :lol:
