2.6 Interface Section

2.6.1 UART Interfaces

PN6280_EVB have two UART interfaces: UART0 and UART1. The UART0 is

non-synchronous

communication interface. The UART1 is as the end of the AP module debug interface. When using

UART1, you need to turn switch(17) to the ON state.

PN6280_EVB will be converts the COMS 1.8V level into a standard RS232 level through serial level

converter chip. Users can connect PC or other terminal equipment through UART for serial

communication. UART0 supports 115200 baud rate default. UART1 supports 921600 baud rate

default.

2.6.2 SIM Card

The PN6280_EVB provide one SIM interface, can automatically identify 1.8V and 3V SIM card.
