RFM69 on one print board or on separate Rx and Tx prints?
-
Hi.
I have a serial gateway working.My next step is creating nodes using RFM69/433MHz.
On the mysensors site there is an (obsolete) AliExpress link to an RFM69 chip that has sender and receiver on the same print board.
What I currently have in my drawer are 433 MHz chips where the sender and receiver are on separate print boards (e.g. https://www.aliexpress.com/item/4001148855756.html?spm=a2g0o.productlist.0.0.12023abf3WwfqH&algo_pvid=8b48b8c5-f4a7-4148-9c76-522f77bb5bbb&algo_expid=8b48b8c5-f4a7-4148-9c76-522f77bb5bbb-10&btsid=0ab50f4415948924536708139e7ccc&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_)Will these also work out of the box with the mysensors libraries (without me having rewrite most)?
Or must I have the RFM69 where the sender and receiver are on the same print board?
I would hate having to wait several months for new components to arrive from China, but as I am not able to rewrite the mysensors libraries myself, I realize I might end up having to do that. -
Hi.
the radio modules you linked are not rfm69, nor compatible.
Yes, you need to buy rfm69 modules. You can easily find them on aliexpress.Thx for reporting obsolete link.

Thanks @scalz for confirming what I suspected. It saves me (and maybe others) time by not going in the wrong direction with 433 MHz chips that are not RFM69.
As a newbie, I thought RFM69 was synonymous with 433MHz communication in general. but I guess it is not. -

indeed it is not synonymous. you can also find rfm69 868mhz or 915mhz depending on which region you live. (868 for EU, and 915 for USA for example). I personnaly use 868mhz because range is good enough for me, requires a smaller antenna and ground plane than 433 (lower freq bigger gnd plane, antenna performance and radiation dependant of gnd plane size which is a part of the antenna, if monopole/coil is used).
But 433 has better penetration than 868 which in turn is better than 2.4ghz.
