My Pixy has been performing quite nicely until recently.
I went to screw it into the mounting bracket on my robot and noticed what looked like some components coming off near the LED.
I got out my microscope and sure enough, it looks like Q2/Q3 are detach(ed|ing) from the board.
Is there a BOM/parts list available for Pixy ?
I could probably fix this myself but would be willing to send it back.
Yikes!
The file you want is here:

In particular, those guys are little transistors that switch the LED:

Cool! Thanks for the doc, it was just what I needed.
I ordered the parts from Mouser and fixed it this weekend.
The LED works, Pixy works, everything is happy 
Thanks!
