Open-X 8M Power Specification
The Open-X 8M development kit power source is provided by either the 12V DC barrel jack, or the
USB Type-C jack. From either the power jack or the USB Type-C jack, the power input branches off
into different voltage rails via step down converters on the carrier board and a Power management IC
(PMIC) on the SOM. The SOM and carrier board is powered by 3.38V via a Richtek step down
converter U400 on the carrier board. The 3.38V is then fed directly to the SOM PMIC. To ensure the
SOM is getting powered correctly, a user can monitor the current going into the SOM via the power
probe header J600 (see section 3.8.4).
Note that even though the hardware design supports powering the development kit solely from the
USB Type-C jack, the software may not support this feature. Please check the release notes for the SW
release you are using to confirm whether it is supported. The release notes are available on the product
support site.
