The WORKBENCH part 3

and 4 G too I assume ?

there is SIM card slot, but I have to check whether it works or not.
interesting thing is antennas on sides, they have u.fl connector but they are not connected.

Maybe you’ll need a LoRacard with LTE and the antennas (2x) are allready in place.
I wanted to use a RAK 7258 for this POC but the one I received didn’t have 4G :pensive:

So I ripped a Huawei B315s-22 for the PCB … they work fine, now I can use a wifi only GW (with Pi zero) or one with an ethernet cable connection .

Hi @jenertsA,

are you a beta tester or did you get it only? It is listed as not available atm. :slight_smile:
For the LTE part - you could also use a combination of:

https://mikrotik.com/product/lora_antenna_kit
https://mikrotik.com/product/r11e_lte
if you need wifi too:
https://mikrotik.com/product/rbm33g
https://mikrotik.com/product/R11e-5HnD or
https://mikrotik.com/product/R11e-2HPnD
if you only need wifi:
https://mikrotik.com/product/RB912UAG-2HPnD or https://mikrotik.com/product/RB912UAG-5HPnD
i guess @BoRRoZ can build a nice case :slight_smile:
or you can use this one from RF Elements https://rfelements.com/products/integration-platforms/stationbox-alu/stationbox-s-carrier-class-2/

Hey,

we got it for testing as beta, at the moment. They say it will be available in next month.

interesting product(s) … sharp pricing :sunglasses:

I want to bring these smd led’s to a frontpanel in the new enclosure.
But the pads and leds are to small to solder even very thin wires.

The idea now is to glue small LDR’s on top of the smd led’s to detect if that led is on/off and control a ‘mirror’ 3 mm led.
Must try… can’t think of another solution :thinking: :disappointed_relieved:

I would solder fine wires (the self fluxing wire wrap type) where the LEDS go and route over the pcb to a connector. Temporary hold the wires in place on the PCB with bits of tape and then paint with UV curing PCB resist to secure in place.

Yes that was my first idea too… but

this is my thinnest wirewrap wire and my smallest soldertip… these leds are very small, I can’t do it ! (without damaging something) frusty

You need the right tools …

I would suggest light-tubes and not modify the board unless really neccessary.
For example this: https://archidelis.at/en/Plastics/Round-Cords/Nylon-Threads-Perlon-Threads-PVC-Cords/PVC-cord-colourless-transparent-5-0.html

yes, that’s a possibillity !

how do you ‘glue’ a light tube to such an smd led ? that’s the same question I have when using a small ldr… I’m afraid that hot glue would melt the leds… :upside_down_face:

  • 5 mm is to big… you know if you can buy smaller diameter ‘flexible led extension light tubes’ ? don’t know the exact name… optical something :laughing:

please explain… I can’t buy a very steady hand :wink:

Well, for me the key to soldering small stuff like that is a very fine soldering iron tip. The finest are pure copper, so they dont last forever.

When I had an expensive Antex soldering iron these copper bits cost a lot, so I switched to the MUCH cheaper YiHUA irons so that I can use cheap copper bits like these (yes 34cents each, delivered) ;

The self fluxing wire wrap wire I already have from the days when wirewrapping stuff was the way to build development systems. Normal fine enamelled wire normally works too, just put a blob of cored solder on the wire end and the enamel burns off leaving a nicley tinned end.

But alas you do need a steady hand …

tnx
I use this one

but I see I can buy an ultra fine pitch iron for it

I use two of these (£30);

One has broad bit for connectors and such, the other has a fine copper tip in.

I also have one of these in the portable toolbag, so I can keep to one set of bits;

Yes 5mm is too big. however I could not find tubes with a smaller diameter quickly enough. It is just the example that matters.

tnx for searching… I couldn’t find it too :wink:

I just ‘hot’ glued the standoffs for the PCB So, that I can reach the simcard without taking the whole thing apart, and I made 'room in the middle for the control switches , your solution is probably not going to work for this case.

I like these… with ‘flip up cover guard’… of course TTN blue for the gateway :innocent:

BTW very nice webstore for all your nuts/washers/standoffs ect

Those fine copper bits come in real handy when you have to solder small stuff, just added a MMA8653FC accelerometer to a PCB …
