VisionCB-RT1176-STD v.1.2 Datasheet and Pinout

General description

VisionCB-RT1176-STD.png


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.

Recovery Jumper/MCU Boot Configuration

VisionCB-RT1176-STD-recovery.png

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
