Ultra-precise milliOhm meter

I created this PCB based on two circuit designs I found on the internet. The device uses a precision current source and a 24-bit AD converter to determine the resistance of an unknown resistor below 5 Ohms. This time I picked the white board color and it is so far (in my opinion) the best color that PCBWay offers. Of course, I haven't tested many of their other colors, but for some reason this white color stands out. The board looks beautiful already without the parts. The holes are drilled properly and precisely and the board is cut well too, so there are no burrs or sharp edges. The white board with the black silk screen looks great as well as it provides a good visibility. It is good for the eyes. I usually put some texts on the top copper layer (not as silkscreen, but as the actual copper layer) and those texts look great, especially when the light comes from a certain angle. I think these PCBs would look absolutely gorgeous in transparent enclosures. The packaging was good, I even got a little present, thank you! Shipping and delivery was rapid as usual.
