Do you know, that annoying module with the missing segment resistors and the dodgy multiplexing, is apparently no longer on eBay? :cold_sweat:

Just as well! :sunglasses:

Current one is this one which is actually properly designed!

One 74HC595 per digit, no multiplexing and the correct resistors.
