PCB is prepared for installation in the case, there are mounting holes, feed-through saws. As long as this device is without the case, you can make the case yourself, all conditions are created for this. Later it will be offered in the case, but that's another story...

Is sketch available? Thanks

[berkseo]

@shajek In the coming days will add a sketch. It's a mix of the standard mysensors sketch and the adafruit sketch.

Thanks for designing this! But I'm having a hard time getting it made. Primarily because of the 0.2mm hole size and there are 2 masks for each of the top and bottom (and I think the PCB manufacturers are having a hard time reading Russian). Has anyone else experienced this or have any of the files been modified since this was posted? I have tried several houses and they come up with the same problems and those that have been able to make it work change the price to about $10 per board because of the hole size.

@thecricketer I had the same problem. It looks like @berkseo is uskng 0.2mm holes for vias. I simply changed the drill file. The T01C0.2 I changed to T01C0.3. Then I checked all the gerbers in a gerber viewer and the slightly larger holes does work.
Pcbway can read the russian file names. 5 usd for 10 pcs.
But, do you have the schematics? If you have the board it would be a guessing game to know that component goes where.

Just adding my archives. I did not encounter problems with file names in Cyrillic.

That the vias where 0.2mm drill and the fab houses I tried charged 10 times extra for 0.2 drill than 0.3.
But I don't think it is a problem changing them to 0.3 (I changed it in the drill file). The copper pads on the vias are 0.5mm in diameter, and a drill with 0.3 will still work.

Green 0.2mm drill, yellow 0.3mm drill, red is copper.

If you change yourself, I think this is not a problem with the inner 0.3 and the outer layer of 0.5 problems will not be

@berkseo Do you have a what goes where description? like this but with a number instead of x

• Rx , Rx----- Resistors 10K 1% 0805 2 pieces
• Rx ----- Resistors 1M 1% 0805 1 piece
• Rx ----- Resistors 470K 1% 0805 1 pcs
• Rx, Rx, Rx, Rx ----- Resistors 4.7K 1% 0805 4 piece
• Rx ----- Resistors 27K 1% 0805 1 piece
• Rx ----- Resistors 20K 1% 0805 1 piece
• Rx ----- Resistors 5.6K 1% 0805 1 piece
• Cx, Cx ---- Condenser 100nf 2 pieces

And the code, could you upload the code for this and for the SHT20 version?

[berkseo]

update! new pcb ver2+case model+experemental sketch

[magpern]

Could you please update the description with what component goes where on the pcb?
