Have a small question LoRaWan was mentioned as a use case but so we know if the Turning pi is capable of SPI over the mPCI slot or will it be the unreliable USB over mPCI

USB over mPCI

Question, what does USB over mPCI mean, does that mean that a lorawan mPCI card will not work?

Mini PCIe can contain multiple signals. One of them is PCIe, another USB. I'm not sure why was it called "unreliable"

Exactly my question, that is what I'm trying to understand, because I'm thinking of adding Lorawan to my TPI

SPI is seen as better matching the clock speed directly to processing. As packets are considered more time sensitive."Unreliable" maybe the wrong word, maybe preferred What you find is the USB over mPCI boards contain there own re-timer chip which is not the best solution but one that works
