Power Probe Header
The following sections will provide in depth information on each expansion headers and connectors on the
carrier board. The information listed below is of particular use for those who want to interface other external
hardware devices with the Open-Q™ 820. Before connecting anything to the development kit, please ensure
the device meets the specific hardware requirements of the processor.

3.8.3 Open-Q Power Specification

The Open-Q™ development kit power source connects to the 12V DC power supply jack J21. Starting from
the power jack, the 12V power supply branches off into different voltage rails via step down converters on the
carrier board and PMIC on the SOM. The SOM is powered by 3.8V via Richtek step down converter U2 on the
carrier board. To ensure the SOM is getting powered correctly, user can monitor the current going into the
SOM via the power probe header J86 (see section below).
