{{ImportantMessage|text=SBC Lynx is extremely flexible in terms of hardware configurations. This document details connector's pinout of common SBC Lynx models. For more information about models not documented here, please contact [mailto:sales@dave.eu Sales department].}}
==Introduction==
This document details connectors, buttons and switches that equip SBC Lynx board. '''Please note that not all of them are available on all models'''.

===Serial console (J42)===
System console is by default routed to this interface. This is typically used during the development stage.
|}
===Ethernet connector (J16)===
J16 is a standard RJ45 10/100BaseT Ethernet connector - incorporating magnetics - connected to the Ethernet controller and PHY.

===microSD slot (J43)===
J43 is a push-pull microSD card slot connected to uSDHC1 port of MX6UL processor.
|13||CD||Card detect||Pulled-up to 3.3V

===USB host port (J48)===
J48 is a standard USB Type A right angle connector connected to the MX6UL USB_OTG2 port signals. The following table reports the connector's pinout:

===USB OTG port (J47)===
J47 is a standard USB Type micro AB connector connected to the MX6UL USB_OTG1 port signals. The following table reports the connector's pinout:

===Mezzanine board connectors (J53/J54)===
J53 and J54 are 10x1-pin 2.54mm-pitch vertical headers for optional mezzanine expansion boards. These boards can be implemented to extend SBC Lynx functionalities and/or interfaces.

[5] '''To be used for voltage reference only'''.
====Handling bootstrap signals====
MEZZANINE_GP0, MEZZANINE_GP1 and MEZZANINE_GP2 are connected to LCD_DATA19, LCD_DATA22 and LCD_DATA23 respectively. As such, they act as bootstrap configuration signals as well. They can be used by application software freely and the can be connected to user's application circuitry. However, '''any electrical interference during the processor reset cycle must be avoided'''.
[1] The same considerations apply to all of LCD_DATAx signals that are routed to J45/J52 connectors.
===One-piece interfaces (J45 / J52)===
J45 and J52 are two interfaces designed to be populated with Samtec 1.00mm-pitch 30x2-pin FSI One-piece connectors. The peculiarity of this kind of connectors if the fact that they
*allow to mate two boards by using one connector only
[2] This signal can be routed here instead of connector J48. Please refer to the [mailto:sales@dave.eu Sale Deparment] for more details.
===DWM WiFi/Bluetooth module connector (J46)===
J46 is a 30-pins SlimStack™ Receptacle 0.50mm pitch that allows to connect to DAVE Embedded Systems' DWM Wifi/BT module.
The following table reports the connector's pinout:
|}
===Multiprotocol UARTs and CAN interfaces===
There are two UART multiprotocol ports (RS232 / RS485 / RS422) and one CAN interface available on SBC LYNX.
CAN interface is connected to MX6UL Flexcan1 controller through an SN65HVD23x CAN transceiver.
====Transceivers' connection====
The following table describes the MPUART0 signals to the ISL3330 transceiver:

===CPU ONOFF / Power reset connector (J50)===
J50 is a 0.100in-pitch 4-pin male header that allows connection to signals needed to implement advanced power modes.
For more details please refer to [[Supported_power_mode_transitions_(SBC_Lynx)|this page]].
==Buttons=====Reset button (S11)===
When pressed, a full power-up cycle is triggered, resulting in a complete hardware reset of the system.
==Switches=====Boot mode (S12)===
Please refer to [[Booting_options_(SBC_Lynx)|this page]].
===Multiprotocol UARTs/CAN settings (S12)===
Please refer to TBD.
