VisionCB-RT1176-STD v.1.2 Datasheet and Pinout
General description
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.

Note:
1. Depends on JP3 selector.
Recovery Jumper/MCU Boot Configuration
RECOVERY is the boot mode selector. If:
- RECOVERY = 0 (jupmer installed) then BOOT-MODE0 = 1, as a result serial loader starts
- RECOVERY = 1 (jumper is not installed) or open then BOOT-MODE0 = 0, as a result MCU boots from fuses
