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: tbnobody/OpenDTU#532 (comment) 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
