Ordering the cable is the easiest and simplest way but if you want to do it yourself (DYI), see cable pin out info below:

The EAP104 console port has a micro-USB interface. It’s a proprietary cable and not standard accessory. You will need a USB UART TTL to micro-usb console cable like below.

The pin definition is as below.

Refer to “Console Board pin connection” definition for the console cable.

Pin	Name	Color	EAP104 pin connection	Console Board Pin Connection
1	VCC	Red	3.3V	3.3V
2	D-	White	UART_RXD0	3V_TX_1
3	D+	Green	UART_TXD0	3V_RX_1
4	ID	Yellow	GND	NA
5	GND	Black	GND	GND

A handmade workaround is to combine a USB to UART TTL adapter plus a micro-B connector.
