I am working on a project with NodeMCU, I have completed the project, you can say a prototype. Now, I want to convert this prototype into a product, so want to design this PCB board.

I have read online that NodeMCU is an open-source board, so can someone please give me the link to download its PCB design files. I want to remove few components to reduce the power consumption.

One related question, as here guys must have worked on PCB boards. I am thinking of using the rigid board for the NodeMCU and flexible PCB for the sensors. So, it will be a Flex-Rigid board. Is it a good option or should I work on the complete rigid PCB. Few pros and cons from the professionals, who has practically worked on rigid flex PCB.

Thanks.

You know NodeMCU has many versions. You can join the grabcad community to get schematics and PCB footprints of different versions.

Flex PCB is useful but it has a disadvantage. It is very costly. If you can afford the cost, it can be the best option in R and D. You can visit contact RayPCB. They fabricate and assemble flex PCBs up to 8 layers.
