Hello, now quite there is no time to do scheme. A very simple scheme is used. Specification on the project page. Ok, problem is that the only device you have made that has any kind of specification is the e-paper temp device with nRF52 chip. It has like "R1, Resistors 1K" then one knows that R1 on circut board is the 1K resistor. On your other uploaded projects it only says "Resistors 1K" - that makes it hard to know where to put the 1K resistor. With some process of elimination one might be able to place the components for the "EFEKTA BME280 Sensor" and this sensor based on the pictures of the competed device on the project page. It is possible to read most of the resistor values from the picture. But for instance the "Temperature & Humidity mini sensor" you can not tell from the pictures what resistor goes where. The pictures are blurry. Could you perhaps upload a better detailed picture of the front and back?

@magpern L1, Inductance 4.7uh 1210 - $0,71 https://ru.aliexpress.com/item/100-SMD-1210-4-7uH-5-NLV32T-4R7J-PF/32853632579.html Also replaced on the project page. Inductance on 4.7 was, apparently they ran out.

@mr_red I have a zipped snapshot of all the 3d step/wrl models that I used to build my projects so far. It was quite some work to gather them all and align with the footprints using the kicad stepup tools. It's not complete - still needs some more work:simple_smile: but it should help you or anyone else to get started into MCAD integration using FreeCAD and kicad stepup tools. Maybe it's not very easy to start when using free tools but hey they are "FREE" so we cannot ask for more. But the nice thing is that once you get used it will be really easy to do your stuff and to go forward. Oh and FreeCAD can be so powerful after you learn it - I was really amazed what you can do with it(it has it's quirks and downsides but once you master it - oh, well...). There's also: https://www.onshape.com/ - pretty powerful this one too and it has more advanced features than FreeCAD but the downside is that it's a cloud based solution: it's free for public documents but you never know when they will go to paid accounts only so yeah...I don't really like the idea to depend on something that it's hosted and the application is not on my PC along with the documents that I create with it. Cloud solutions have their flexibility but you're locked and you depend entirely on that hosted service. Ok, enough talking...I uploaded the zip file here: http://www.mediafire.com/file/kzh1l9uo40cpj1u/kicad_stepup_packages.zip

Hello. Any news from this project? Do you made the changes for the timer TLP?

I am still using several temp/hum sensor and they are running great I also have just added code and pictures for my newly build light sensor (using an LDR).
