It’s just that a couple of people who seem to have them did ask as they didn’t get it working, so I was just wondering if that had been solved already
Just FYI - I now have my RAK831 connected to a NanoPi Neo running the go-version of TTN packet-forwarder. xenial and go version 1.9. RAK831 reset is connected to PG11 on the Neo. Power is provide by 12V PSU into LM2596 DC-DC converter See below a pic:
My Board is now finally available! https://www.tindie.com/products/kilobyte/rak831-raspberry-pi-breakoutbackplane/
I drop this here in case someone else needs it, as the dwg file was missing the connector location - so I made one that states them as they appear in that file:

For comparison, RHF0M301 draws 1.66 watts when idle / RX. (At 5.34V, 0.31A) Very nice the RAK831 draws about 1.03 watts when idle / RX!
Hi James… nice info.
That picture is from RAK … I will measure it myself also
tnx Jac. … it seems alive
whats your aerial setup? aerial type/cable type/cable length/inline adapters?
@ the moment a typical indoor GP living room set up
Yes I think a GP will give a better result (indoor/outdoor) then the supplied antenna … but I use the GP only for testing, I have an outdoor antenna.
would you get the same distance from the RAK supplied aerial?
Do you know which lora gateway board support LBT?
I am using the 915Mhz version, with TTN P.F. I have managed to make it work, but only for a few hours, now looks like it is connected in TTN but it does not receive the packages, also notice that the LED RX no longer lights, I will try leaving it off for some time to see if it is a problem of temperature or voltage, which are the two topics I have read may be the cause. Additionally, could anyone confirm if (–reset-pin 25) actually works?
It works for me! (mind you, this is pin 22 on the GPIO header!)
I noticed the temperature of the RAK pcb after 30 min, could it that the RPI is heating the RAK831 when you use a converter PCB ?
That is a fairly normal temperature for a concentrator board. The MultiTech mCards are at finger burning temperature when used with an PCIe-to-USB convertor. Other concentrators are also well above room termperature in my experience.
So (imho) nothing to worry about.
I’ve the same problem with my 868MHz board. After few hours it stops receiving packets. When I restart ttn packet forwarder it start working. Packet forwarder makes the board reset (pin 25).
I have the RPi and the RAK831 in a “RPi casing”.
The CPU core temperature was in the 55-65 degrees range and the RAK831 got warm (I would not say “hot”).
Now I have added a small Cooling Fan that blows at the back of the RAK831. The CPU core temperature is now in the 30-35 degrees range. I have no way of measuring the RAK831 but I expect it to run cooler also.
who supplies the tall case?
