@Koresh I do like it, i just worry for people that use their main PC as a controller. Easily knockable/damageable unless they use a rear socket.
Simple USB-RFM69 gateway without additional functions.

@sundberg84 Do not worry. It's not a very difficult design. ATmega is a relatively slow chip (I mean slow edges) and we have not long high speed data lines. So we do not need impedance control production and it is just 2-layer board (I have experience in multilayer design but it's really not needed in this case ;)). RF69 chip has no separate analog ground and even in reference boards all gnd pins are connected directly. RF ground planes are just decoupled without ferrite beads but may be I will add them, not sure yet if they are needed.
@Samuel235 This board contains usb UART-TTL converter (CH340, see bottom layer of the board and schematic which I will upload soon) so of course you can use usb to connect gate to controller. I have been using this device only for one day today and I find it really awesome. Very convenient
I'm also here for some design files to learn from. It looks awesome, not too sure how applicable it would be, how do you plan on utilising this, is the usb port there for data or just power? If it is data, are you having it connected to your home automation server constantly?
@Koresh - woaw, RF PCB design - 4 layer or what do you use?
Via stitching for analog ground? How do you connect analog/digital groundplane together? F. Bead?
Man... so much to learn!
Please release the design... Im sure I have alot to learn from it.
@NeverDie
Thanks for the known shortcomings. Some thoughts about solutions.
@Cliff-Karlsson See PM

Great project! Can you share the scheme of your project? I want to
familiarize with your device more closely.
Thanks! I will share schematic after applying some fixes.
