Spool3D says that they have "v1.3" boards, but I only see v1.2 here if the commit history is to be believed.

Also, the link to the schematic PNG in this blog post is broken.

The schematic for version 1.3 is the same as for version 1.2. Only the PCB layout is different.

thanks for making the circuit
Is this possible to use it with glass (stuck with 3M blue tape on top) ?

Consider reading the blog post detailing the project [here]( https://miscsolutions.wordpress.com/mini-height-sensor-board/) which states supported surface types.

so anything with nonreflective surface should work fine (for me blue tape on glass, which makes it non reflective)

Why were changes needed for the PCB layout between 1.2 and 1.3 if the schematic was the same?

Answer 6 · 2019-01-28T14:08:19.000Z

To make manufacturing easier.

Is there any reason it cannot be made smaller? Say doing the same design but with edge mounted SMD sensors?

The width could be slightly smaller, it is limited by the spacing needed between the phototransistor and the outer IR diode. The height could be reduced by using a attiny44a MCU in a flat pack package instead of attiny25 and smaller connectors and programming pads, or perhaps a single 6-way connector for both. We intended to switch to a JST 1.5mm connector but we had push back from one of our OEM customers.
