Mobiflight Displays

[sharp estuary]

I have read where mobiflight works with max7219 2×4 7-segment display. My question is, is the only available color red LEDs? Looking for white ones or something else compatible where I could get white instead of red. Thanks in advance!

You can buy white digits from the Mobiflight shop and support the project

Currently have these if anyone could help me with rewiring them (simple tutorial to get me started)

The digits seem to be mounted on a different board than the max7219 board you are showing.
You should confirm they are common cathode. Only those will work.

There are many sources in internet showing how max7219 should be wired. You of course also need to know the pinout for your digits.

By the way, the max board you showed is actually for driving a Led matrix, not really for digits, although it will work.

I gotcha. Looks way to complicated anyway. I like the simplicity of the ones they recommend just hate that red color

Jaime gave you a source to buy displays that are in white

I saw. Do they work with the mega 2560?

[lime meadow]

Yes, they work with anything

[sharp estuary]

Thank you!

[sharp estuary]

I will order when they get back from the sim expo

One more question before I purchase. Don’t mean to be a pain in the _ . These will work directly with my mega 2560 or will I need the breakout board also?

[lime meadow]

The breakout board just makes it easier to connect to your arduino. If you have another method of connecting between the pins you can use that instead.

Ok. So tell me if I have this correct.

I would need (2) 3-digits….. hdg & spd

And (2) 5-digits …… altd and vs

So I would have to wire each one I’m assuming with the normal 5v,G,Din,CS,CLK?

And can they be daisy chained?

Or could I get the breakout system with everything pre wired where it just needs to be plugged into arduino

[lime meadow]

They can be daisy chained. You daisy chain Din/Dout, CS, CLK and provide separate 5V to each board
