Interfaces and Functions

DC Power

SB-UCMIMX93 main power should be supplied using 12V DC power supply included in the evaluation kit. Adapters for European AC and US AC outlets are included. Connect the power supply to connector J4.

Serial Console

To begin using serial console connect your host PC to the micro-USB connector P16 using the USB cable from the evaluation kit.

Display

MIPI-DSI

SB-UCMIMX93 supports direct connection with the Startec KD050HDFIA 5" MIPI-DSI LCD panel.
Connect the display data cable to connector P11.
Connect the display touch-panel cable to connector P12

LVDS

SB-UCMIMX93 supports direct connection with the Startec KD070HDTLA020 7" LVDS LCD panel.
Connect the display data cable to connector P7.
Connect the display touch-panel cable to connector P8

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-iMX93L 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-iMX93L 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-iMX93L reference guide and SB-UCMIMX93 schematics for additional details.

RS232

One RS232 interface is available via DB9 connector P17.
Please refer to UCM-iMX93L reference guide and SB-UCMIMX93 schematics for additional details.

Multi-functional signals access

I2C

I2C interface is available via header P3.
Please refer to UCM-iMX93L reference guide and SB-UCMIMX93 schematics for details.

ADC

ADC signals are available via header P3.
Please refer to UCM-iMX93L reference guide and SB-UCMIMX93 schematics for details.

GPIO

GPIO signals is available via header P3.
Please refer to UCM-iMX93L reference guide and SB-UCMIMX93 schematics for details.

System

Reset

Pressing the reset button SW2 triggers system hardware reset.

Boot Sequence Selection

Pressing and holding the SD-boot button SW3 during power-up or hardware reset forces UCM-iMX93L to boot firmware from an SD card in socket P15.
Pressing and holding the SDP-mode button SW4 during power-up or hardware reset forces UCM-iMX93L to enter Serial Download Mode.

Power ON / OFF

Long press on the Power On button SW1 shuts down the device.

RTC

RTC is implemented on UCM-iMX93L and receives power from coin-cell battery BH1.
Jumper E9 must be shorted for correct RTC operation.

JTAG

JTAG interface is available via header P4.
Please refer to UCM-iMX93L reference guide and SB-UCMIMX93 schematics for details.
