having a portfolio of products with different PCBs does not necessarily mean that one needs to manage a different code base repository for each PCB. for the products in the portfolio that follow the same general functionality of sensor sampling, streaming, maybe some edge computing and transmitting of the data, one can actually build one common and configurable code base that does not care on which PCB it runs on. here is a blog i wrote on the topic: https://medium.com/augury-research-and-development/insights-on-the-re-architecting-to-a-single-firmware-codebase-running-on-different-hardwares-dbbbbcc3aaae
