A carrier board for NVIDIA's flagship robotics computer.
Carrier board for the NVIDIA Jetson Thor module, built for robotics. It brings out multi-gigabit and Gigabit Ethernet, HDMI, USB-C, M.2 expansion, camera and coaxial I/O, audio and a TPM around the module's high-density board-to-board connector, with its own wide-input power stage. Designed in KiCad on a 12-layer stack-up.
The board
The 12-layer board is built around the Jetson Thor's high-density board-to-board connector. It adds an optical transceiver cage, two RJ45 ports with magnetics, two Microchip LAN7430 Gigabit Ethernet controllers, a Lontium LT9611UXC HDMI bridge, USB-C ports managed by TI HD3SS3220 controllers, two M.2 sockets, three coaxial connectors and two flat-flex camera/display connectors. Power comes from a wide-input TI LM5116 buck stage with Infineon MOSFETs, followed by Vishay SiC431 point-of-load converters.
All layers combined: the module connector fans out across the top of the board into high-speed Ethernet, HDMI, USB and PCIe routing, while the power stages are grouped on the left with wide copper pours kept clear of the signal area.
