GPS Hat and FONA at the same

Post by dannya »

Is there any way to use the Pi GPS Hat and hook up a FONA to the same Raspberry Pi?

Thanks!

Not trivially.

The RasPi only has one hardware UART, and software UARTs aren't reliable on time-slicing operating systems. You could use a multiplexer to switch between the devices, or you could use an USB-to-UART or I2C-to-UART adapter for one of them.

We don't have any I2C-to-UART devices, but we do have some USB devices:

Thanks! Would I be better off using an Arduino Mega? Would that work just fine with those two devices simultaneously?

Yeah, the Mega has multiple UARTs, so it should be able to handle both devices comfortably.
