@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?

update! new pcb ver2+case model+experemental sketch :)

[magpern]

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