Notes on 7 Segment display that I have used. Mostly to jog my memory if I return to the project. Perhaps you'll find it useful too.

I bought several of these 5in. 7 Segment LED Common Cathode Display, Red at MPJA

Resources

• LiteOn P/N: LTS-50301HRB data sheet. I didn't see the pinout on the data sheet. I wrote it on the backside with a sharpie after pinning it out with a DMM on diode function.

• Serial driver for large seven segment LED displays at Tindie.Com

• HIGH-VOLTAGE SEVEN SEGMENT LED DISPLAY DRIVER WITH SPI INTERFACE documentation
• rm-hull/luma.led_matrix python 7 segment library (matrix too)
