I have an large format 5x7 segment LED display that I want to control over I2C.
It uses ELS-1806GWB LED blocks and currently has what I believe is a IDE (40 pin) ribon cable and plug. The board only has LEDs on it, and the IDE-to-LED tracks are easily traceable as there are no ICs, resistors etc on the board.
I presume I’ll need something like a 4511 BCD decoder, and an I2C interface board.
Just about all the I2C backpacks I’ve seen are sold as for something like 16x2 LCD displays. Are these a good place to start, or are there ready-made I2C boards I could use?
