<br />
==Ethernet==<br />
SB-UCMIMX93 provides Ethernet port via '''RJ45''' connector '''P13'''.<br />
<br />
==CAN bus==<br />
One CAN bus interface is available via terminal block '''J21'''.<br><br />
Terminal block plug is included with the eval-kit.<br />
Please refer to UCM-iMX93L reference guide and SB-UCMIMX93 schematics for additional details.<br><br />
<br />
==RS485==<br />
One RS485 interface is available via terminal block '''J22'''.<br><br />
Terminal block plug is included with the eval-kit.<br />
RS485 bus on-board termination can be enabled by shorting jumper '''E12'''.<br><br />
Please refer to UCM-iMX93L reference guide and SB-UCMIMX93 schematics for additional details.<br><br />
<br />
==RS232==<br />
One RS232 interface is available via DB9 connector '''P17'''.<br><br />
