== General description == | |||
[[File:VisionCB-RT-STD-1-0-1k.png|center|700px]] | |||
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. | |||

Notes:<br /> | |||
1. All I/O lines are 5V compatible.<br /> | |||
2. RESET line is 5V compatible.<br /> | |||
3. Preferred voltage range on AIN0…AIN3 lines is 0…+3.3V.<br /> | |||
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.<br /> | |||

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.

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. |
