I ordered one of these yesterday:
Maybe I can use some nixies on my next front panel display…

btw… if you have a lot of led’s in a project and need to reduce the current these are handy
US $1.79 incl. shipping
one jumper to switch off all system led’s for testing

My first “production” sensor node. Pro Mini and BMP280. Tomorrow I’ll look at designing and printing a case for it.

this one can program the things gateway?
yes… but let’s try it first, I let you know here 
- yes I see LED’s
flashing bootloader
MPLAB IPE v4.15
getting debug info
I’m thinking of hooking up a spare RPI3 to ‘parse’ this debug info
Ok, so it is safe to order this one?
absolutely.
there is a nice feature build in… but not operational yet and that is (will be a firmware update) … you can plug in a micro sd card with the firmware you want to flash (think community help flashing GW’s)
Also the cable doesn’t come with it (made myself)
gateway is running now (tested with TTN node ) but I have to make a little uart cable to get some debug output

I ordered one the same way you did. I live in Holland

ok… I know the guy / company behind it… 100% 
he is very active on Tweakers (MUX) and he orders from his Farnell account, but the goods ships direct to you… this one came from the UK within a few days by courier costing only his 2 E extra.
I do order this way when I need Farnell products because I don’t have a business account there (or anywhere 
)

I knew the initiative but have never ordered with him. There is always a first time.

I’d a day off work so I designed this node case.
Needs a few tweaks still (and didn’t spot the clogged nozzle till too late) but I’m pretty happy for a few hours’ work.

Today was the first sunny day since a long time…
Although it was pretty cold outside, my indoor gateway was sunbathing in the afternoon!
Perfect day to verify the fan was keeping the temperature on target
Happy with the result

I have a Raspberry Pi / IC880A DIY gateway with @dbrgn backplane. The backplane has a temp sensor and can drive a fan, so it is very easy to implement, but it can be done with any gateway. I would just recommend using a temp sensor and not rely on the cpu temperature as the resolution is not good enough to stabilise a PID controller.
The controller code is available on github

I had seen them on AliExpress starting from 2 (or 3?) pin versions.
How are they / how is the quality?
Could you post another picture next to some other (familiair) object for a size impression?
Thanks.
