ESP DMX Endpoint

Wireless DMX access to DMX fixture via ESP8266 and WLED or ESPixelStick

This is my first PCB. I haven't ordered it yet but would like to get some feedback on pitfalls etc.

The ESP8266 (Wemos D1 Mini) together with and RGB LED and some resistors is on the top layer and the MAX485 (responsible for DMX) plus the connectors are on the bottomlayer. There are 3 holes to mount the PCV to the fixture.

Things I don't like: CN1 is the power connector (5V input). I use XH2.54 connectors. In the library I found the 3 pin which is needed for the DMX out end but I couldn't find a XH2.54 2 pin connector so I simply used the 3 pin and not use one of the pins. No big deal but would replace it with a 2-pin if there was one. Of course the other option is to build one with the library/footprint manager but that was a bit too much given this is the first one.

The auto route (local) finished without issues and I ran the DRC check without errors. So as far as I can see with my limited beginner knowledge this PCB should be good to go.
