VisionCB-8M-STD v.1.1 Datasheet and Pinout
General description
VisionCB-8M-STD is a carrier board for the VisionSOM-8Mmini family of computer-on-modules which are powered by NXP SOC iMX8Mmini (quad core ARM Cortex-A53+ single Cortex-M4). 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, PCIe, 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.
VisionCB-8M-STD is equipped with Segger J-Link debugger and Linux serial console port on USB vCOM.
