💬 NRF2RFM69
-
It was just a quick one I created today on openhardware, so not finished yet..
I'll order a batch of them one of the next days (just need to panelize them).
They are perhaps 1 or 1.5 mm wider than the normal NRF module, as I have used the dimensions from the Sensebender as a template..
-
Nice. Will you also create a KiCad part for this?
-
Exactly. Suppose it could just be a copy of the current nrf24 footprint but with extended courtyards.

Some time ago, I saw such a converter board on OSHPark. If I find the link again I will post it. But this one seems more compact :-)
-
Here is the link to a similar board: http://hallard.me/rfm12b-breakout/
BRD files and link to OSHPark are available, it's open source as well. -
@tbowmo Indeed :-) smaller is better.
-
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..

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.
-
@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?
-
I've added the panel design to dirtypcb's store.. So just order it from the following link
http://dirtypcbs.com/view.php?share=16378&accesskey=4e199dccdf623eab0c90fddbc4786f80
@tbowmo Is this a complete module with components? Because 10 pcb for 41$ is a bit expensive.
-
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.
