💬 NRF2RFM69

@tbowmo Indeed :-) smaller is better.

[scalz]

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)

[[[global: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.

:+1:

@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
