UART (Universal Asynchronous Receiver-Transmitter) is a medium-speed digital signalling bus standard.
In terms of stats:
- Two traces
- Up to 1.5 Mbit/s
- Impedance not specified
- No clocking necessary for synchronisation
- Serial bus routing topology
- Low driver output impedance
The two trace connections are single-ended and should be routed with a shared ground connection.
