  • Love how tiny that is, but I’m not a fan of the pin layout on those little Xiao modules. The connection pads on the bottom, including the battery connection, are a major pain to try to solder to. If I ever get around to playing with the remaining two I have, I’m gonna try using pogo pins or something instead of trying to solder onto them

    Edit: I do really like that it has external antenna connectors for both Wifi/BT and LoRa (unlike my Heltecs). Assuming I handle the battery charging and convert to 5v externally (to avoid dealing with the annoying battery pads) they’d make a great “attic node” (in my case on a mast in the back yard) that could stay connected to my wifi rather than having to remote admin it over LoRa (Slow and not all config options are available)






  • I don’t think that will work. At best, it would split the signal power and neither antenna would perform well. That’s not even getting into the RF wizardry which I’m not equipped to fully explain (or understand lol).

    The “proper” solution would be to have two Meshtastic units. One in a high place for long range and configured with the “client base” role and the other one(s) with regular antennas optionally in the “client mute” role. The reason for that is they’d likely be able to “hear” the base station one just fine and relay through it and wouldn’t necessarily need to rebroadcast locally. If they do, then they can be in regular “client” role.

    Since I have multiple units inside, I keep mine in “client mute” when I’m home so they go through my “attic node” and switch to “client” when I’m out and about. The 2.7 firmware makes this easy to switch directly on the device without having to mess with the app settings.

    Now if you’re talking a highly directional Yagi for the high gain/high place antenna, then I believe the general guidance still stands. The newer firmware has some zero hop configuration where you can “pair” devices (via favoriting) and while they still hop the signal, it doesn’t decrement the hop count.

  • Yeah, it’s hard to know if people use the word “repeater” colloquially or technically, so I always repeat the Meshtastic warning about that role since it has a high likelihood of being detrimental to the mesh in the area.

    Hope you find something suitable because it’s a fun project. I only get a few hits each month (less in the winter it seems) but it’s cool when you randomly pick up someone from miles away and have a chat.



  • I’m not aware of any ready-to-use ones you can buy that are outdoor rated. Pretty much all of the pre-assembled ones I’ve seen are in a handheld or portable form factor.

    For a “repeater” node (note the quotes, explained further below), I’ve wanted to pick up one of the new 1 W high power Rak Wireless boards (link). Those have a battery terminal as well as a solar input for charging. All you’d need to add would be a PV panel + battery and put it into some kind of housing. I’d also use a nicer antenna than the little stub one that comes with it.

    You should be able to put that together without any kind of soldering, though you would need to wire the solar panel output to a battery-style connector to be able to attach it to the board. There are solder-free wire splicers you may be able to use, but it’s also a good opportunity to practice soldering as there’s little to mess up.

    For the housing, you might look for outdoor-rated utility boxes or something like that. Would probably have to drill and seal holes for the antenna connector and solar panel wire, but shouldn’t be too difficult. That, or you may be able to get a friend to help with 3D printing a solution.

    Now, back to the use of “repeater” instead of repeater. Meshtastic docs are very adamant about only using the repeater role (now “router” role; repeater has been deprecated in recent versions). In all but the rarest and most optimally placed cases, you’d want to be using “client” or “client base” modes as they repeat messages but without forcing other clients to use them (and thus consuming a hop).







  • Thanks. It’s basically a travel router + portable app server + media library. I wanted to play with the much more capable Pi Zero clones and it turns out they can run quite a bit of stuff at the same time and the features snowballed as I just kept adding more stuff (I got the models with 4 GB RAM).

    This would be great for parents too

    Definitely, at least once I add some GPIO switches to set different modes for the networking (that’s kind of a pain point now if you need to setup a different wifi client connection, switch its internet connection from wifi to USB tethering from a connect phone or switch the ethernet port from LAN to WAN, etc).

    We had a power outage during a snow storm week or so ago and the prototype ran all day from a power bank and kept a limited Jellyfin library online for everyone (mostly Star Trek and Marvel movies since those are the only things everyone in the house can agree on haha).
