UART Speed vs USB


I’m developing a project based around a Pi4 and the Hat and the EC25-E. I’d really prefer to use a UART implementation for ease of case deployment. Can anyone confirm if the max potential CAT4 LTE speed can be achieved via UART.


Hi @steve-3446,
It is not possible to obtain the full CAT 4 speed via UART as it limits the speed.
It is recommended to use USB.
