new in my shop: Light detector, 5V, based on photodiode and opamp -- 5V daylight intensity sensor, for direct connection to AD converter of microcontroller tindie.com/products/offerman/l "A modern alternative to the traditional voltage divider circuits based on photoresistors (i.e. LDR's containing cadmium). Photodiodes provide only a small current when light is falling onto the silicon, so they need an operational amplifier before the output can be delivered to an AD converter for readout."

No 24-channel driver chips available before May/June, or even 2023! ( TLC5947, PCA9956B, PCA9957, PCA9626B).
What to do: wait, or redesign using cascaded chips with less channels?
