Gateway on OSH Park

[gloob]

Hello,

Does anybody know the following gateway PCB for a WeMos from OSH Park?

https://oshpark.com/shared_projects/59hasWWz

Are they correct? Can I order some?

Depends.
It was tested (and works) with NRF24L01 radios, but I'm still waiting for my RFM69 modules to show up to test these.

On top of OSH they are also on PCBs.io, if you prefer black to purple.

See my github repo for more infos, it will also be on openhardware when fully tested etc.

Thanks for the feedback. Sounds good that the PCB is working. I did order some PCBs some days before and will also test it when they arrive. I will give some feedback here.

For me the PCB looks like an easy solution to build up a gateway with OTA functionality.

To I need to add all components even when I skip the ATSHA chip? Can I skip the 4.7k and 0.1uF SMD parts?

Yes you can skip everything except C1 (you can use any 4.7-47µF here) and the radio module.

If you have them around adding C2 and C3 is always a nice touch as it will remove some extra noise from the power supply but they are not required.

Even the voltage regulator should not be needed, but if you are using a PA+LNA or RFM69HW and have some Tx issues adding it should fix it, but at least on the WeMos D1 mini Pro the 3.3V regulator seems powerful enough in my tests.

I have now received the PCBs.

Do you have an image how you mounted the Wemos? I think I will end up with a bigger distance between the PCB and the Wemos, because the voltage regulator is under the ESP.

@gloob
Yes, see https://www.openhardware.io/view/303/MySWeMosGWShield

I have now received the RFM69 modules and seems to work (at least nothing wrong in the debug log, I don't have any RFM69 node to test yet).

@hek could you merge this to https://forum.mysensors.org/topic/5580/myswemosgwshield to regroup all discussions on only one forum thread? Thanks!

@emc2, unfortunately not possible to merge discussion in the forum.
