Hi, I’d like to buy The Things Uno board. I’m from the Philippines…do you have any suggestion where I could buy it? I tried looking up to the RS website but it doesn’t ship to the Phils. Not sure about farnell though. But is there any other asian market which sells this board? Thanks in advance.
Hi, I’ve just started working on TTN uno; it connects, I see messages and all seems work as expected; now it’s time to start sendint real data instead of fake data, so I have to start connecting sensor; as my understanding digital pin 0,1, 5 are not available because used by RN module, is it correct? are all other PINs available?
Hi where can I find a tutorial to solder on an external antenna? Thanks.
Nick that wasn’t very helpful - first thing I did was a search 
There’s an article from 2016 which refers to the following instructions, but the link is broken:
https://www.thethingsnetwork.org/forum/t/schematic-things-uno/3020/3
The search link I provided from my bookmarks yields the post that was linked to above as the very first entry. And you gave no indication that you’d searched the forum. What search terms did you use?

I thought there might be some kind of “official” document from TTN! So basically I split the sheath and solder to the two outer pads, and the inner core goes to the left hand side of R18, removing R18 in the process, does that sound right?
I’d get a U.Fl connector - marginally more robust but yes, the two outer pads are ground and the centre for the core, remove R18, glue 1cm of cable to the PCB because if you lift the track, your board will need some delicate repairs.
Thanks Nick, much appreciated.
Hello.
I recently purchased a Things Uno and a Things Network Indoor Gateway. Everything is working and I managed to get a little sketch working that logged data to the TTNMapper project.
Neat!
I’ve got a project I’m working on where I don’t have wired power and am thinking about incorporating solar power.
I ran across an interesting looking battery shield that can be charged by a solar panel:
I’m concerned if I use this shield, the Lithium ion battery, being so close, might negatively impact the antenna on the Things Uno.
Any thoughts?
Thanks!
John
That does look like a very impressive piece of RF shielding, Gucci black & stealth bomber shapped.
You could look for a shield that supports an external battery so it’s not covering the Uno board… Or search the forum / Google for the external antenna modification so you can have the antenna away from that shield.

Thanks! – It’s a little expensive, but I might pick one up to test out for other projects… I’ll probably end up with an external battery charging module for a 3.7V Lithium Ion cell and then use a Boost module to get up to a regulated 5V for the Uno. (Bulkier, but won’t get in the way of the antenna.)
Hi again.
Another antenna-related question – What is the antenna pattern for the Things Uno board’s PCB antenna?
I’m putting my unit in a plastic enclosure and it will be mounted to a pole. What’s the best orientation for the Uno?
I’m assuming I want the long axis of the Uno parallel to the long axis of my dipole antenna on my outdoor gateway, but I’m not sure. RF has a way of being counter-intuitive! 
Thanks!
Regards,
John
Whatever the pattern I suspect if pole is metallic you may find shadow effect/reduced signal in that direction and if too close may see some de-tuning of antenna, though that may apply more to much larger antenna. May be worth mounting a bit away from the pole, say >1/2 wavelength? Best way to find out is test no doubt others will chime in with better knowledge & expertise…
Thanks, Jeff.
I was thinking of using some ABS pipe as the last part of the mounting structure for the same reason. Maybe I’m over-thinking it, but hey, that’s what engineering types do!
I saw a bunch of people with the same issue as me in this thread but nobody posted a solution…
Adriono IDE returns this:
Sending: mac join otaa
Join not accepted: denied
Check your coverage, keys and backend status.
But when i look on the gateway it says the join IS accepted and shows som payload data…
I have the TTN UNO and the TTN Gateway (backers edition)
Why isn’t the UNO behaving properly?
Do you have at least 5 meters distance between the gateway and the node to make sure the gateways transmissions do not overload the nodes receiver circuit?
Well… that’s misleading.
There is no such thing as “denied” in LoRaWan - there is merely, “did not receive an accept”. - but that could either because the request was not accepted, or because there was a communication issue in either direction, including a confusion over frequency if a node too close to a gateway overloads it and falsely appears on channels other than the true one.
But when i look on the gateway it says the join IS accepted and shows som payload data…
Please be specific: Please show both the join request message, and the resulting join accept response.
Hi,
Yeah… you are right. It’s simply things being too close together. I moved the GW up to the attic and now the TTN UNO no longer shows connection errors.
Thanks for your quick responce.
