VisionCB-RT-STD v.1.0 Datasheet and Pinout
General description
VisionCB-RT-STD is a carrier board for the VisionSOM family of computer-on-modules which are powered by NXP i.MX RT application processors (ARM Cortex-M7). A carrier board, together with a System on Module (SoM), makes a complete development platform similar to SBC. The carrier board houses the most common interfaces such as USB, Ethernet, UART, etc. A large variety of interfaces allows to use it as both a complete development platform or as a stand-alone end-product.
The carrier board connects with the SoM via a standard SODIMM connector.

| 4 | DIO11 | UART2-CTS | Default: UART2 CTS line or universal GPIO with 5V logic levels. |
| 5 | DIO12 | UART2-RTS | Default: UART2 RTS line or universal GPIO with 5V logic levels. |
| 6 | DIO13 | UART2-RXD | Default: UART2 RXD line or universal GPIO with 5V logic levels. |
| 7 | GND | GND | - |
| 8 | AREF | VCC-3V3 | +3.3V generated by internal SOM LDO converter (limited load current). |
| 9 | DIO14-SCL | UART5-RXD | Default: UART5 RXD line or universal GPIO with 5V logic levels. |
| 10 | DIO15-SDA | UART5-TXD | Default: UART5 TXD line or universal GPIO with 5V logic levels. |
Notes:
1. All I/O lines are 5V compatible.
2. RESET line is 5V compatible.
3. Preferred voltage range on AIN0…AIN3 lines is 0…+3.3V.
4. Voltage level compatibility can be changed to +3.3V with removing R901 and mouting R902 (0R), but voltage range on AIN0…AIN3 lines must be 0…+3.3V.
User LEDs connections
| LED | PCB symbol | GPIO | Description |
|---|---|---|---|
| D400/blue | GPIO10 | GPIO1_10 | Default: JTAG MOD input or universal GPIO with 3.3V logic levels. |
| D401/green | GPIO11 | GPIO1_11 | Default: JTAG TMS input or universal GPIO with 3.3V logic levels. |
| D403/yellow | GPIO12 | GPIO1_12 | Default: JTAG TDO input or universal GPIO with 3.3V logic levels. |
| D402/red | GPIO13 | GPIO1_13 | Default: JTAG TDI input or universal GPIO with 3.3V logic levels. |
Notes:
1. LEDs are switched on by logic „1” set at the GPIO outputs.
2. LEDs are controlled by current drivers and do not load the GPIOs.
User switches connections
| Switch | PCB symbol | GPIO | Description |
|---|---|---|---|
| S402 | GPIO3 | GPIO1_IO03 | Universal GPIO with 3.3V logic levels. |
| S403 | GPIO4 | GPIO1_IO04 | Universal GPIO with 3.3V logic levels. |
| S404 | GPIO8 | GPIO1_IO08 | Universal GPIO with 3.3V logic levels. |
| S405 | GPIO9 | GPIO1_IO09 | Universal GPIO with 3.3V logic levels. |
Notes:
1. After button pressing on GPIO lines are set to „0”.
2. GPIO lines connected to switches are separated from board’s environment by 1k resistors.
