Ian, Yes! I had that chip in my list of ones to test. Can't find any TLC5916 anywhere, BUT can find sporadic stock of TLC5917. The TLC5917 looks identical except it says it adds short protection detection? It also can run 3.3v, so saves a level shifter if running an ESP. Do you know if there is a cross reference to another pin compatible driver from another manufacturer? I try not to lock myself into one manufacturer if possible, especially these days.
My other option was high power '595 shift registers like the TPIC6B595. Benefit being it may be a more 'universal' part in case I need more in the future. I agree the ESP32 is a bit overkill.. but it worked so well in my prior clock I'll likely use it again. Plus code reuse, I should need minimal changes and only have to maintain essentially one piece of code for multiple clocks.
