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.

Notes:
1. Linux console port (UART4 in MPU) uses vCOM interface provided by built-in debugger Segger J-Link.
2. vCOM can be disconnected from MPU with JP801 (jumper CONSOLE in position ON or OFF).
3. Lines TXD and RXD of UART4 are easy to monitoring thanks to using J304 gold-pins.
4. Debug JTAG interface can be disconnected from MPU with JP800 (jumper JTAG in position ON or OFF).
