ConnectorsEdit

Power supply connector (J35 / JP1)Edit

J35Edit

Pin #	Name	Description	Notes
1	GND	Ground
2	VIN	Positive supply voltage	Range: 5 ÷ 24 V

JP1Edit

Pin #	Name	Description	Notes
1	VIN	Positive supply voltage	Range: 5 ÷ 24 V
2	GND	Ground
3	GND	Ground

Serial console (J42)Edit

System console is by default routed to this interface. This is typically used during the development stage.

Pin #	Processor ball	Name	Default function	Default type	Notes
1	K14	UART1_TX_DATA	UART1 transmit line	Output, 3.3V LVTTL
2	K16	UART1_RX_DATA	UART1 receive line	Input, 3.3V LVTTL
3	-	3V3_IO	UART1 I/O voltage reference	3.3V
4	-	DGND	Ground	0V

Ethernet connector (J16)Edit

J16 is a standard RJ45 10/100BaseT Ethernet connector - incorporating magnetics - connected to the Ethernet controller and PHY.

J16 integrates a status LED providing connection information:

• LED on: link established
• LED blinking: activity.

The following table describes the interface signals:

Pin #	Name	Function	Notes
1	TDP	TX+
2	TCT	TX center tap
3	TDN	TX-
4	RDP	RX+
5	RCT	RX center tap
6	RDN	RX-
7	NC	Not connected
8	CHS_GND	Chassis ground	See also this page
