The SOM Carrier board is a reference design for custom carrier boards using Embedded Artists SOM boards.

SOM Carrier board design
This is a new reference design specifically for our SOM boards, with several enhancements of features and usability:

  • Support for RZ/G3E SOM designs
  • Support for i.MX8M Mini SOM designs
  • Support for M.2 Key E interface (typically Wi-Fi/BT)
  • Support for M.2 Key M interface (typically SSD)
  • Support for M.2 Key B interface (typically Cellular)
  • On-board MIPI-DSI to HDMI bridge

Many RF solutions
The on-board connectors such as M.2 (both E-key and B-key) and uSD makes it simple to add RF solutions. Our family of Wi-Fi/BT M.2 modules (based on Murata modules) are directly supported.

Supported SOM boards
The SOM Carrier Board is compatible with the following SOM boards:

Note that all interfaces/connectors are not available for all SOM boards. It depends on what interfaces the processor in use supports. Check the respective SOM datasheet for details.
