7 segment or Matrix display

Post by Silly_Rabbit »

I'm looking to create a clock using 6 digits, and each digit needs to be separate so the 4 digit backpack display isn't really an option.

I just saw the RGB - 7 segment Digit that might work but is the a bigger chain than 3 75HC595's as stated in the description?

Alternatively, I can use the LED backpack but that also stated only 4 matrixes in use.

This would be to possibly recreate a nixie tube operation. I assume all of these can be soldered off the 4 pin header with longer leads.

Thanks for the help.

You could use 2 of the 4 digit backpack displays together.

Of course that's 8 digits, but maybe you could mask off two of them. If you want to go the route of using the 8x8 matrices, then you could use an I2C muxer to get past the 4 backpack limit:

yea, they have to be single digits and not grouped in a set. I'll have to do some research on the I2C muxer. Honestly I'm pretty new to this so that seems complex.
