I’d like to pair the Xavier with an Epiq Sidekiq M.2 board for software defined radio applications and was wondering if the interface on Xavier would work?
I see that Sidekiq has their M.2 card coming in Key-B and Key-M formfactor and Jetson-Xavier does have an M.2 Key-M slot. So, yes, you can use it.
Although as WayneWWW suggested, you may have to check with Sidekiq for the driver support for the Linux kernel version that runs on Jetson-Xavier.
