We recently purchased a 2nd YDLidar G4. The first one came with a small bag of screws for mounting the Lidar puck onto the mounting plate, but not the second one. Would anyone be able to confirm the specs on those screws? (length, flat counter length/width/angle pitch, screw pitch & length)? It would be a nice touch to come with them instead of putting the burden on the customer. Also just to make sure – is the 2nd power cable a microUSB2/charging compatible?
