It was not clear in the documentation, but how many UARTs are available on the Onion Omega? I know there is one, but is there more?
Reason being is that I noticed the GPS expansion uses USB and obviously uses a USB serial port, but my application requires a USB port for audio capture via USB sound card. So I need GPS and USB audio.
Was the reason for the decision to use a USB serial port on the GPS expansion because the Omega only has one UART? None of this is clear in the limited documentation.
@Jonathan-Rizzo The Omega has one UART available. We chose to use a USB serial port on the GPS Expansion because we are generally planning to move to USB-based expansions and the interface for this particular use case is very simple.
We're working on expanding our hardware documentation, thank you for your patience and stay tuned!
Thank you for the reply! What solution would you have then, for use of multiple USB devices or more than one serial device for a battery powered application? Possibly this SoC wasn't made for applications for that, but maybe expansion boards could be made with USB hub controllers and a connection for an external power supply. I certainly would pay the extra cost.
@Jonathan-Rizzo Yup, it's certainly in our pipelines!
