[J22] The camera connector supports up to six directly connected cameras via
•
CSI-2, or up to 12 cameras via the virtual channel feature of CSI-2. The connector
also includes some interface options for audio (I2S & DMIC).
[J24] The voltage select header enables either 3.3V or 1.8V for these [J21] 40-pin
•
expansion header pins:
Pins 7, 12, 13, 16, 18, 19, 21, 23, 24, 29, 32, 33, 35, 38, and 40
The 3.3V level is selected when a jumper is on [J24] pins 1-2. The 1.8V level is
selected when a jumper is on [J24] pins 2-3.
[J25] Use the included developer kit power supply with this DC power jack.
•
[J26] 30-pin expansion header includes:
•
o Power pins.
One 1.8V power pin, one 3.3V power pin, and one 5V power pin. These are
not switchable; power is always available when the developer kit is
connected to power.
o Interface signal pins.
