Small ESP32 hub for 8 NTC temperature sensors

I'm a beginner in PCB design and made an ESP32 based temperature sensor hub to monitor my hot water system in various locations. The first review pointed out missing files, but I could just re-upload everything without an issue. The production was really fast and the quality really good. Delivery took quite long because I chose the cheapest option (due to low part cost), but that is not PCBWay's fault and there were no issues with customs. Overall it's a really great service.

    We outsource SLM parts for our customers since we don’t have an SLM machine in-house, but the customer was very happy with both the quality and the fast turnaround of the parts.
    Excellent quality. Well made and it works ;))
    Everything went smoothly, the PCB turned out great, even with the line art on the back side. The stencil worked great too. As always big thanks to the PCBWay team for yet another awesome PCB!
    After assembled I shall edit the sketch of operation and displaying.
