These #PerkinElmer ACULED VHL (Very High Lumen) LED modules have a different pinout for IR vs visible. I think their 730nm LED module follows the IR pinout, even though it's red, not quite IR.

I figured this out the morning after ordering boards from #Sunstone (formerly #PCBExpress). I'm so grateful Sunstone was able to cancel my order with a full refund. 😊
