4.8. UART Interfaces (J401/J402)

The UMTS&LTE EVB offers two UART interfaces: COM1 (Main UART port J401 and J402) and COM2

(Debug UART port).

COM1 of UMTS&LTE EVB is intended for the communication between the module and the host

application. It can be used for data transmission and AT command communication.

COM2 supports 115,200bps baud rate. It can be used for Linux console and log output.

The following figure shows the block diagram of UART on UMTS&LTE EVB.
