Here is a second description as follow up of my first post hacking a laser distance meter for Arduino Nano support.
The second device looks identical to the first one from outside. But there is a different board inside. That fits to a report of one blog commenter who is trying to modify his own device as well. In sum we got three devices with three different board layouts so far, apparently looking the same from outside.
Board front side.
With space for a wireless add-on board, Bluetooth maybe?

Former keyboard controls wired up. Large capacitor buffering power supply.

I’m finally hacked a cheap laser distance meter from Amazon. Arduino Mini is taking control. Someone else tried before but gave up on this. Mine looks the same like the KKMOON but has no brand marking.
