SpaceCB-8Mplus-ADV v.1.1 Datasheet and Pinout
General description
SpaceCB-8Mplus-ADV is a carrier board for the SpaceSOM-8Mplus family of computer-on-modules which are powered by NXP SOC iMX8Mplus (quad core ARM Cortex-A53+ single Cortex-M7 + Neural Processing Unit). 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 3.0, USB-C, dual gigabit Ethernet, HDMI, 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.
SpaceCB-8Mplus-ADV carrier board is equipped with HDMI + LVDS + MIPI-DSI video outputs, 24-bit audio codec, PCIe 3.0 (M.2 key M) socket (2242, 2260, 2280), RS-485 and CAN-FD interfaces.
SpaceCB-8Mplus-ADV carrier board is equipped with Segger J-Link debugger and Linux serial console port on USB vCOM.
