Based on idea/ realization of breakout board https://github.com/dokuhn/openDTU-BreakoutBoard
Very first beginner trial to do first own PCB.
Unfortunately wrong lib for SSD1306 used, so display is not fully at desired location
Goal is to have a PCB with NodeMCU + nRF chip + SSD1306 display (not size optimized)
Picture of first full assembly:
Issues: None, initially could not get the display running: https://github.com/tbnobody/OpenDTU/discussions/532#discussioncomment-4935189 However with upgrade of firmware to https://github.com/tbnobody/OpenDTU/commits/b5d099f it is running now :).
First version for case can be found in the openscad directory. Updated now with picture of case, fits perfectly.
5 PCBs not used, if anyone interested in Munich area, pls do not hesitate to contact me.
Second PCB version now in production: https://github.com/SteffMUC/openDTU_wDisplay2

Questions
How big is the OpenDTU wDisplay PCB?
It measures 104.1 × 50.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OpenDTU wDisplay use?
9 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the OpenDTU wDisplay KiCad files?
From the SteffMUC/openDTU_wDisplay repository on GitHub, at the commit this page was made from: the board is kikad/openDTU_wDisplay.kicad_pcb and its schematic kikad/openDTU_wDisplay.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenDTU wDisplay design in my own project?
Its repository states no licence, so its author keeps all rights: ask SteffMUC before reusing the design.
