Orange Pi Zero expansion for sensors

I made a PCB project for an expansion board (Orange Pi Zero). It was intended for weather and indoor air quality monitoring. I was more than satisfied with PCB quality. The only trouble was my own error in the schematics :) All the contact plates are made perfectly, mask and silkscreen are both great. Besides, the price is reasonable. Going to make more orders here. I strongly advise you to order board checks if you can't make simulation of schematic yourself (or if you forgot to do so, like me :)
