https://youtu.be/dgQWt7Z3ekoIn the video I compare the following 4 microscopes with built in displays:
Generic 4.3" Microscope that records 720P and takes 3MP photos
Generic 2.5" Microscope that records 720P and takes 3MP photos
Andonstar ADSM201 Microscope that records 1080P and takes 12MP photos
Andonstar ADSM302 Microscope that records 720P and takes 12MP photos
I have seen the ADSM201 discussed on this forum and by Dave. The ADSM302 is the recently released newer model of the ADSM201. They seemed to improve on some of the gripes people had with the older model.
The camera sensor is larger and the working distance has been increased by quite a bit because of the elongated tube for the lens to move.
The screen is larger and higher quality with the ability to adjust the angle.
The base is much larger and heavy than the previous model. It is also black compared to the reflective silver of the older model. The silver made it hard to look at single components without glare.
