I don't understand why they populate MiniPCIe vs an M.2 slot. Anyone know? Only thing I can imagine is the key variants for M.2 are more complicated.

- numpad0 7y agoCompatibility? Something like Iridium radio might still be using miniPCIe. And you wouldn’t want adapters in embedded.
- srcmap 7y agoMiniPCIe allows for adding wifi, network, storage (M.2) and other cards. M.2 limit to only storage.
- XMPPwocky 7y agoM.2 can be used for PCIe (including NVMe, wifi+bt, LTE modems, etc), SATA (storage only), or other weird stuff depending on the keying.
- Const-me 7y agoAfaik large share of embedded WiFi/BT and 3G/4G chips are USB ones?
- throwaway2048 7y agom.2 can have USB lanes aswell
- dagi3d 7y agoAren't there WiFi and Bluetooth cards using the M.2 interface?
- aaronmdjones 7y agoYes. The A/E keys allow for PCIe and USB, among others. My Intel Wireless-AC 8265 WiFi+Bluetooth card is an M.2 22x30 card.
