MBI5030 – 16ch LED constant current LED driver starter board

Macroblock MBI5030, 16-ch constant current LED driver with PWM, SPI-like interface, requires external grayscale clock. Known-good source: Kingelectronics, latest datasheets. The problem: you need the chip to figure out if your code actually works. And you also need the LEDs to see what’s going on – if at all. You could use a logic analyzer,
