UART Level Shifter?

Hey,

Thanks for this project. Very helpful as a reference as I'm learning to do this myself :)

I'm just curious, according to the SIM7000 User Manual the UART interface of the SIM7000 operates at 1.8V, while as far as I can tell the ATMEGA is running at 3.3V. Did you not have to use a level shifter between them to get UART to work properly? Or do you know if the breakout board perhaps has that built in?

Best,
Simon
