The B101/B102 is a HDMI to CSI bridge with I2S Audio Interface designed for the Raspberry PI/HummingBoard. The difference between the B101 and the B102 is the data rate that can be sent over CSI-2. The B102 features 22-pin FFC-Connector with 4 lanes. The B101 only supports a 15-pin FFC-Connector with 2 data lanes.
Nvidia Jetson (Prefered platform)
Raspberry Pi models A, B, B+, 3
HummingBoard
Keep in mind that your choice of platform will require a proper Devicetree and driver implementation to work with the B101/B102. For further informations please contact support@auvidea.eu
