VERSION 1.0
J20 (38223)
Features
J20 six camera adapter module for the NVIDIA® Jetson
™
TX1 dev kit
The J20 adapter module is specifically designed for the TX1 dev kit. It plugs into the 120 pin CSI-2 camera
socket. Six 2 lane CSI-2 interfaces are provided. The 15 pin CSI-2 connector is compatible to the Raspberry Pi
camera connector. Up to six identical camera modules may be plugged in. To access all 6 cameras individually
3 I2C busses are used. Each bus connects to 2 connectors. To separate the 2 cameras on a single I2C bus, the
2nd connector (J2_x) is connected through an I2C address translation device. This changes the I2C address of
the camera so that 2 cameras can coexist on the same I2C bus.
Software drivers
The J20 is intended for software developers who wish to develop a software driver for setups with multiple
cameras.
• Ridgerun (ridgerun.com) is developing drivers for multiple Raspberry Pi camera setups. Please contact
Ridgerun for details.
• Raytrix (raytrix.de) is developing a driver for their C41 4k CSI-2 camera module. Please contact Raytrix for
details.
