Hi,

I have a case with a two digit turbo display.
I search how to wiring this display and how to configure it. I check the site minuszerodegrees but i don't find any match with mine

The attachment 20240819_134118.jpg is no longer available

The Turbo Button is already wired on the display. So i think it's good
+5V and G are easy i think, so normally i put here the 5 volt from the power supply ?

But, T+ and T- ... What can do with this header ? The display have no jumper, so i think is used for configuring ? Maybe temporary use the reset button for configuration ?

Can you help me to not make a mistake ?

Regards,

That's correct.

Those conenctions seem to be the positive and negative connection for a Turbo LED. I don't see any configurability on that display. Can you unscrew it and take a picture of the front side of the PCB? It's possible that the frequency display is fixed to two different speeds, so maybe it is not configurable at all. The PCB you show does not have the possibility to control individual segments of a speed display.

Ok, You are right.
I just wired the 5V and the display show HI or LO depending the button's position.

Yep, it seems (from comparing the front and back photos: the actual display seems to only have 4 pins) that the logic causing those 2 combinations to light up is baked inside the actual display panel!

And, surprisingly or not depending on how you see it, it seems that nobody's making those 4-pin displays either 😀
