The J100 board has the same form factor and size as the TX compute module. The board is plugged in below the TX1 or TX2 and brings out many interfaces on connectors. The J100 can be plugged in a specifically designed modular motherboard to bring out more interfaces and to integrate it with other components for UAV applications.
The Auvidea J106 carrier board is the integration of the J100 and the J20, so that 6 CSI-2 cameras or 6 B101/B102 modules may be connected.
All of the boards can support the Jetson TX2 through a firmware patch.
