Product Disclaimers
Ensure proper handling and soldering procedures to maintain product integrity. Verify specifications for your specific application requirements.
Unfortunately I havent tested the 5G, Only difficult part was connecting antennas. But everything is good, by default it runs on Qualcom's QMI mode, Had to switch to MBIM and it works good with Windows. Planning to run with OpenWRT soon.
