General description
is a carrier board for the VisionSOM-STM32MP1 family of computer-on-modules which are powered by STMicroelectronics STM32MP15x application processors (single or dual core ARM Cortex-A7 + internal microcontroller 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 debugger, USB, Ethernet, UART, 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 SODIMM200 connector.
