Overview
********

.. warning::
    We recommend using the :ref:`OAK-D-CM4`, the latest model, unless you are sure you need this one.

Based on the Raspberry PI CMIO board, the OAK-D-CM3 (BW1097) combines a host and the :ref:`OAK-SoM <bw1099>` to allow 
for fully integrated solution for real-time spatial AI.

Getting started
***************

The OAK-D-CM3 accepts 5V (+/-10%) from a 5.5m x 2.5mm barrel jack. Raspberry PI USB boot can be accessed by setting a header jumper, which allows 
initial flash of eMMC on CM3/CM3+. Alternatively the microSD slot can be used with a bootable system image. The Raspberry PI JTAG header is not 
populated by default, but can be added, allowing JTAG access.

The reset button resets the OAK-SoM only. To reset the CM3/CM3+, ground the RUN header via to the GND header via.

The PWR LED indicates "power good" for the BW1097 on-board PMIC. The ACT LED indicates activity on the CM3/CM3+ device. Other indicator LEDs exist 
for the two USB2.0 Type A ports and for the 10/100 Ethernet port.
