At first glance they look very good, silk screen is fine, both on top and bottom. The outline of the board feels smooth with a sharp edge, just as it should be.
Let’s have a closer look.
Even close up, the silkscreen looks fine, this text is only set to 0.8 in Eagle, with 8% ratio and vector font.
When looking at the alignment of the different layers, you can see they are a bit off. On the bigger pads it isn’t a problem, but on the smaller ones it is very close to the edge of the holes, same can be seen on the via’s. Still, with the layers a bit offset to each other, it changes nothing of it’s function. And considering the price, it really isn’t that bad.
Time to put some parts on!
First some SMD components, hand soldered with a soldering iron, so the soldering isn’t that good looking…
And with almost all components on. So close!
The next I need to do, is to solder the 2×4 header connector in, and mount it in it’s case.
After putting the 2×4 header in, I could put the ESP8266-01 module in, connect the DHT22 sensor, and test it out for the first time…
