How to connect a unit with UART connection to M5Stack Fire?

Recently I realized by reading several posts in this forum that M5Stack Fire UART port C can not be used since the pins are connected to PSRAM. Without knowing that I have purchased several units like GPS which requires a UART connection. Is there any alternative so that the units can be useful (and I do not waste my money)? BTW just curious, what Core of M5Stack is targeted for the units which require UART connection.
