The JNX400 is a quad carrier board for the Jetson Nano, TX2 NX or Xavier NX.
The key application are inferencing use cases in low energy data centers.
Any mix of compute modules is allowed. The master manages 3 slaves with control (console UART) over power up, reset and flashing (USB). The power supply is optional.

3D model (STEP)

The key applications:
– H.264/H.265 transcoding
– processing of many compressed video feeds from network IP cameras
– inferencing applications in low energy data centers
– designed for 19″ rack integration and open rack systems
– desktop use: flashing station for Nano, TX2 NX and Xavier NX

Each compute module slot has a local NVME SSD with up to 2 TB. Optionally we integrate the Transcend TS2TMTE662T2 (2 TByte industrial grade NVME SSD).
The JNX400 integrates a 5 port GbE switch which connects to each of the 4 compute modules.
On top we have integrated four 5Gbit communication channels:
1. 2x horizontal: USB 3.0
2. 2x vertical: 2 lane DSI to CSI-2 (full duplex bi-directional)
On the JNX400 there is a little drawing between slave 1 and 3. Here the hardware is done – but the challenge now is to develop software (drivers) for it.

Limited rev 1 samples are available now. Limited production (rev 2) is planned for late Nov 21. Rev 2 will clean up the fan wiring.
A second use case for this board could be a flashing station for Nano, TX2 NX or Xavier NX. Here the master slot would be populated by a Nano.
The 3 slave slots can host the modules to be flashed (in parallel). So 3 modules can be flashed in parallel.
