Sure that would be great. The lead looks like the the one used to connect the phantom controller up for updates.Not now, I ordered 3 of those leads. That one is now cut open, measured 5.0V DC at all sorts of Tello battery levels.
I’ll knock up a DC circuit with 4 LEDs in it and 1 current limiting resistor then see how to make them look pretty.
Do you want the eBay link?
