==UARTs interface ==
The UARTs interface available on the Evaluation Kit are mapped to the following connectors:
* J25 is a 6x1x2.54 pitch vertical 54mm horizontal socket header for the UART4 port. This is a Digilent Pmod™ Compatible connector for the UART Pmod™ Compatiblemodule (6-Pin Pmod™ Compatible Connector Digilent Pmod™ Interface Specification Type 4 UART) [[File:AXEL Lite-EVB-PMOD-connector.png|thumb|center| 500px|PMOD configuration]]
* J21 is a standard DB9 male connector for the configurable UART5 port. The board provides some configuration options for the selection of the UART mode (RS232/RS422/RS485 with auto-direction)

* UART4 can be used with a PMOD adapter or with a TTL peripheral
* UART5 is a MultiProtocol that support (after harware Jumper configuration) the RS232, RS4222 or RS485 protocols. The related ''device tree file'' has to be properly configured too for enabling the GPIO transceiver configuration, see [[DESK-MX6-L/Pheripherals/UART#Configuring_the_RS232. 2FRS485_mode | Configuring the RS232/RS485 mode]]
