PCBV1R00 has a layout error for the footprint for the LLT M14 6 pin connectors used for RS485 – the pin numbers are incorrect

Pin 1 = RS485 A
Pin 2 = 0V PWR
Pin 3 = +V PWR
Pin 4 = RS485 0V
Pin 5 = RS485 B

Use a SS16 or 60V 1A SMA equivalent for D12
Use R17 68K, R18 10K for 9V75 Undervoltage

Use a ISL81487LIBZ or equivalent for RS485 driver (5V 250kBit ESD protected)
