Cool. I have some Charles board (hallard.me) but these are nice too ;) Maybe you already know it, but if you want rfm69cw is a little bit smaller. It works like rfm69(h)w, but not pin compatible. I don't know why they did this..

I use this NRF modules:

Very cool Thomas - just ginned up some OSHPark compatible gerbers from your repo... Sweet!

What value are you recommending for the cap?

[tbowmo]

@blacey

Hmm.. just a 10uF or something.. Don't know if it's needed at all.. I just added it as a "nice to have feature" :)

I have squeezed the outline a little bit though (haven't updated on github yet though). as I'm trying to put as many as possible on a 50x50mm pcb.

[scalz]

@tbowmo: +1 :) plus it may help to absorb current spikes in TX on battery which can help to extend its life I think... rfm69 is a little hungry boy. 10uF, nor 100uA, is maybe not enough to bufferize on transmit but we could dream a little, what I am doing :laughing:

Witch file do I upload to Dirtypcbs to get the panelized version?

[tbowmo]

I've added the panel design to dirtypcb's store.. So just order it from the following link

It would be great if there was a version of this that had line level converters built in. (For those of us using non 3.3v Arduinos)

[A Former User]

@tbowmo Is this a complete module with components? Because 10 pcb for 41$ is a bit expensive.

[tbowmo]

It's because PCB way don't like panelized pcb's. So they charge it as 3 separate pcb's. If you follow the link above to dirtypcbs, you'll get the panel. I'll have to create the gerbers for a single board again, and upload that to oh, before we can get a normal price there.

@tbowmo I used the dirty link - I don't like that you get no contribution. Have you a paypal or something I can make a small donation to?

[tbowmo]

@shabba

dirtypcb's do have a cashback thing in their "dirty pcb shop" so I should receive 1$ per order.

If you feel the urge to spend some paypal money, you are welcome to chip in on the mysensors project with donations :)

[shabba]

Donation was well overdue. Thanks all.

@tbully @fets

Feel free to "roll your own" :)

I'm on batteries for most of my sensors anyways, so only using 3V (2xAA batteries).

[fets]

@tbowmo ;)
That what I thought but I'm not familiar with pcb design software.
I'll make a try someday

@tbowmo: Any chance to add this to oshpark? I only need 6 piece max.

Not using oshpark, sorry..

[alexsh1]

@tbowmo I understand that the rfm69w goes at the bottom of your adapter. Is this the case? Do you have any photos at all?

Thanks
Alex

@tbowmo
You can upload your files on OSHPark and share them, even if you do not order anything from them. As you use KiCad, the gerbers would be fine. They accept Eagle brd files as well.
