Processor Model (B01)
Note:
The B01 has a UART subset as well as GPIO (4 pin UART (tx/rx/rts/cts)
If needed, use the GPIOs for additional UART signaling.
The USB port can switch between a connection to the radio or a connection to the processor. The
USB selection is controlled via programming on the processor. There is no USB between the radio
and the processor.
