[[File:VisionCB-RT1176-STD.png|center|700px]]


VisionCB-RT1176-STD is a carrier board for the VisionSOM-RT1170 family of computer-on-modules, which are powered by NXP i.MX RT117x  application processors. The 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 audio codec, USB, Ethernet, UART, RS485, CAN 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.

=== Applications ===
* Digital cluster
* Home Control Panel
* Home Automation – Smart Home
* Human-machine Interfaces (HMI)
* Point-of-sales (POS) terminals

Note:<br/>
1. Depends on JP3 selector.<br/>

== Recovery Jumper/MCU Boot Configuration ==
[[File:VisionCB-RT1176-STD-recovery.png|center|600px]]
RECOVERY is the boot mode selector. If:<br>
*RECOVERY = 0 (jupmer installed) then BOOT-MODE0 = 1, as a result serial loader starts<br>
*RECOVERY = 1 (jumper is not installed) or open then BOOT-MODE0 = 0, as a result MCU boots from fuses<br>

Notes:<br />
1. Depends on MCU type.
2. All digital I/O lines are 5V compatible.<br />
3. RESET line is 5V compatible.<br />
4. Preferred voltage range on AIN0…AIN3 lines is 0…+3.3V.<br />
5. Voltage level compatibility can be changed to +3.3V by JP3 selector, but voltage range on AIN0…AIN3 lines must be 0…+3.3V.<br />
