e-Link32 UART Connector – CN8

This is the e-Link32 integrated USB to UART function, which is called the “Virtual COM port”, 

CN8 is the UART side connector. 

CN8

Description

Three UART connector pins: Txd, GND and Rxd 

The e-Link32 will send data on the Txd pin while data will be received on the Rxd pin

Extension Connector CN4-1
