The next issue might be that they only have them in die form. The issue after that probably is that you really want the version 3 (or 9) chips that actually work with all the modulation schemes. I’ve been down the road with a number of similar chips that took *many* rev’s before they really did what they were intended to do.

We changed the die coat on the ASIC to an opaque version soon after that … Light does indeed interact with semiconductors. It happens even on circuits that you would not *think* are photo sensitive. Physics is nasty that way ….
