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.

While there are no outside markings, the inside reveals the manufacturer – SNDWAY. Seems to be an SW-A40.
