<![CDATA[Replacing T-Call SIM800 with T-Call v1.4 on my custom PCB]]>Hi,

I have a custom PCB designed around the LilyGo-T-Call-SIM800 board and wanted to know if this is pin to pin compatible (replaceable) with T-Call V1.4
Can I switch the T-Call SIM800 board with T-Call v1.4 without any changes to hardware/firmware?

Thanks
