@tsunami - i dont know the range, but I have designed a PCB with SMA connector for RFM69HW. You can check out my files how I did it.

@mickecarlsson - I understand your point, and I have changed this back and forth and also asked @Anticimex becuase its a but unclear in the documentation.

MysX 9 + 10 should go to a Digital IO with interrupt, and D2 and D3 is the only pins with interrupts on mini.

I guess you are refering to Mysx_D3_INT but this is the MysX name.

@arden - welcome! I just set up HASS with MySensors and once you get familiar with HASS its quite easy. The MySensors integration was pretty much "out of the box" and not more complicated than any other addon in HASS.

its on controller (hass) connected to one gateway. Then you can have 255 sensors for each gateway. If you have a room and put a node there (uno/mega is fine) you can connect many sensors to each node.

@eme im sorry - since your wrote "The provisions to attach sensors are not correctly marked. D6 doesn't actually connect to D6 pin on the Arduino" I thought you was talking about the MysX connector and not flash. If you mentioned flash I would probably found the issue. They are not talking about D6 but pin 6 on flash which connects to D13 on the Arduino.

Are you sure it's the same problem? Not much that sounds the same.

Sorry for this. The flash has been untested by me. I will fix this asap and upload new files.

The schematics is wrong:

New schematics:

The same error goes for RFM version

New gateway going live and migrating slowly from Domoticz to Homeassistant. At least to try it.

@eme - its is very strange - I have a big batch here with Rev 10 and i checked atleast 20 of them randomly and all have continutiy between D6/pro mini and D6/MysX. You must have had extreme bad luck and if you check the others it should be ok.

Can you post a picture (close up) of the board not working please showing D6/Pro mini and D6/MysX.

For 12v I would use the prototyping area with a 12 > 5v converter. If you want to use the internal voltage regulator on the pro mini you can connect to RAW but beware that clones will not handle this very good. The specs are 12v but I have seen many bad clones getting destroyed.

I dont really remember this image and from which context this is from. I guess the lines represent different voltages. Adding 12V on reg and a 12>5v regulator on the TO92 footprint will convert and feed the board 5v, but kill the radio...

@eme Thats me - ok, good to know then - but I guess you mean the Mini pins and not Nano since the PCB doesnt support the Nano?

@eme good you found the issue. First time I ever hear of a comfirmed PCB hardware bug, so its very rare. Very strange the silkscreen were moved or not aligned correctly as well. From where did you order the PCB?

The documentation states which pins connect to what on the PCB, so make sure you check that out. D9-D13 are used by the radio as in all MySensors projects. D8 for the extra flash. You can find the MysX documentation here as well if you need to find out more about the pins.
