Diamond Systems STEVIE : STV-AGX32-03 NVIDIA Jetson AGX Xavier 32GB Industrial Carrier Board with Single GbE and 16 GPIO

A camera-led AGX Xavier design often needs compute, video and a few digital lines, not analogue measurement or four serial ports. The STV-AGX32-03 is the economy model of the Diamond Systems STEVIE industrial carrier board, supplied with the NVIDIA Jetson AGX Xavier 32GB module installed and programmed with Linux.

The AGX Xavier 32GB module delivers up to 32 TOPS from a 512-core NVIDIA Volta GPU with 64 Tensor Cores and an 8-core Arm v8.2 64-bit CPU, with 32 GB of 256-bit LPDDR4x memory and 32 GB of eMMC on the module. A camera connector with 4x 4 CSI-2 lanes takes four 4-lane cameras, or up to eight 2-lane cameras, through an adapter board, which suits multi-camera inspection and robot vision work. Where analogue inputs and outputs are needed, the STV-AGX32-01 and STV-AGX32-02 add a microcontroller with six ADC inputs, two DAC outputs and 13 GPIO.

The STV-AGX32-03 has one Gigabit Ethernet port on a single, lower-height RJ-45 jack, plus two USB 3.1 and two USB 2.0 ports, two HDMI outputs, two CAN ports and audio. Two RS-232/422/485 serial ports cover a PLC or instrument link, and an I2C GPIO expander provides 16 GPIO lines for triggers, indicators and interlocks. Storage and expansion run to an M.2 2280 NVMe socket on four PCIe lanes, a UFS flash and microSD socket and a full-size Mini PCIe socket with PCIe and USB for flash or I/O expansion modules.

The STEVIE board is only slightly larger than the AGX Xavier module itself, and the most-used connectors sit along the front edge with commercial-style panel I/O, so it can mount behind an enclosure panel with fewer internal cables. It takes 9-20 V DC, and Diamond rates the carrier from -40 to +85 °C. The AGX Xavier module itself is rated -25 to +80 °C, so the module sets the operating limit for the STV-AGX32-03. The same carrier is available without a module as the STV-BB03.
