Issue: Lab staff ordered the USB version of the RAK2287 instead of SPI version.
Setup: Raspberry Pi 4B + RAK5146/RAK2287
Details: I am an IoT developer working for a wireless systems lab that must procure all material through “proper channels”. I put an order request for a RAK2287 SPI w/GPS, but instead the materials manager ordered the USB version without the mini PCIe to USB connector. My question is, since I do have the RAK5146 Pi Hat, am I able to use the RAK2287 USB version at all, or were the SPI lines not even routed in the USB version, rendering the module I possess completely useless without the PCIe-USB converter? I have installed the RAK2287 onto the RAK5146 Pi Hat, and subsequently onto the RasPi, however, after installing the firmware the LoRa Concentrator does not power up. To emphasize how I know I received the USB version, both the actual module and the plastic packaging say “RAK2287 USB w/GPS”. Any help would be greatly appreciated!
