X-40 laser tape reverse engineered

Rebuilding cheap laser tape measure to universal laser rangefinder

I have bought cheap Chinese "X-40" laser tape. 

I disassembled it and found that it is really contains laser module that I reverse engineered earlier:

But the module version is "701A", it's not like "512A" that I bought earlier:

It can been seen that some components are placed at another places.

I want to continue reverse engineering: measure some parameters like APD voltage, desolder  some SMD components  and measure their values. It can help me to increase parameters of  laser rangefinder module.
