USB

SB-UCMIMX93 features two USB2.0 ports that are derived from the i.MX93 USB sub-system:

• Connectors J5 and J6 – USB type-A connectors

SD card

SB-UCMIMX93 supports SD card storage through micro-SD socket P15. Pressing and holding the SD-boot button SW3 during power-up or hardware reset forces UCM-iMX93 to boot firmware from the SD card.

Ethernet

SB-UCMIMX93 provides Ethernet port via RJ45 connector P13.

CAN bus

One CAN bus interface is available via terminal block J21.
Terminal block plug is included with the eval-kit. Please refer to UCM-iMX93 reference guide and SB-UCMIMX93 schematics for additional details.

RS485

One RS485 interface is available via terminal block J22.
Terminal block plug is included with the eval-kit. RS485 bus on-board termination can be enabled by shorting jumper E12.
Please refer to UCM-iMX93 reference guide and SB-UCMIMX93 schematics for additional details.

RS232

One RS232 interface is available via DB9 connector P17.
Please refer to UCM-iMX93 reference guide and SB-UCMIMX93 schematics for additional details.
