I’m building a central receiving device for a project with edge nodes based on RAK19007 + RAK4631 transmitting over LoRa. The receiver needs a fair amount of compute for aggregation and processing, so I’m planning to use a Raspberry Pi 4.
Right now I’m connecting the Pi to a RAK19003 + RAK4631 over USB and reading data from the serial port. As I’m starting to design the enclosure, I’d like to confirm whether this is the right approach or if there’s a better way to connect the Raspberry Pi to a RAK module. I also want to share code between the edge devices and the central unit, so having an RAK4630/4631 on both sides is a plus.
Are there RPI HAT / WisBlock base boards you’d recommend for the receiver side with a Pi, or should I look at solutions from other brands?
Thanks in advance for recommendations.
