Help identify some drivers (pics)

Hello you guys.
I've laid my mitts on some circuits here, but I don't really know what they are.
I was hoping maybe some would recognize these.
RED is one side.
GREEN is the other side.

I think no. 1 and 6 are flexdrives, but what version?:thinking:







Thanks for your help.:beer:

#3 and #4 look like IR drivers for greenies. They look like
most in China 532's.

#1 and is a flexdrive v5
#6 is a flexdrive V4
#2 Looks like an earlier model of the flexdrive, possibly V3 or earlier.
#3 and #4 look like linear IR divers from a green laser
#5 looks like a boost driver for an IR diode also from a green laser

I think...?
