VisionCB-iMX93-STD Datasheet and Pinout
General description
The VisionCB-iMX93-STD (with SOM equipped with heterogenous i.MX935x processor) is a carrier board for the VisionSOM-iMX93family of computer-on-modules which are powered by dual-core NXP MPUs (2 x ARM Cortex-A55 + Cortex-M33). 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 USB, Ethernet, CAN, RS485, audio codec, etc. A large variety of interfaces allows to use it as both a complete development platform or as a stand-alone end-product. The VisionCB-iMX93-STD is equipped with a simple user interface consisting of 4 buttons and 5 LEDs. VisionCB-iMX93-STD carrier board is also equipped with a large number of popular peripherals, including: RS485, CAN, 10/100/1G Ethernet, MIPI-DSI and camera connectors, serial console port on USB vCOM.
