UART1 interface supports 9600, 19200, 38400, 57600, 115200, 230400, 460800 and 921600 baud rates, and the
default is 115200bps. It is used for cellular (LTE/GSM) data transmission and AT command communication.
UART3 interface supports 115200bps baud rate. It is used for outputting GPS data and NEMA sentences.
2.7 PCM Voice Header
A standard 2x4 (2.54mm) male header is used to
provide one Pulse Code Modulation (PCM) digital
interface and one I2C interface to external CODEC
extension board. PCM voice header pin definition is
shown below:
