VisionCB-8M-ADV v.1.1 Datasheet and Pinout
General description
VisionCB-8M-ADV 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-ADV carrier board is equipped with HDMI/LVDS and MIPI-DSI video outputs, 24-bit audio codec, PCIe (M.2 key M) socket (2242, 2260, 2280), on-board RTC with battery socket, RS-485 and CAN FD interfaces. VisionCB-8M-ADV carrier board is equipped with Segger J-Link debugger and Linux serial console port on USB vCOM.
