Things you should know before committing:
- The Sprocket is bare-bones. It has no Ethernet port, no HDMI, no miniPCIe and no SD slot — just 1x USB OTG, one x4/x2 MIPI CSI-2 input, 2x UART, I2C and 4 GPIO on a +12 V to +16 V DC input. For a UAV that needs telemetry, CAN or a network link, the RTSO-9002U at 32 g is the lightest option that still carries 1x GbE, 2x CAN, 2x USB and a miniPCIe socket with SIM, at −40 to +85 °C. connecttec... +1connecttech.com ↗“single-sided with all parts under the module, and brings out 1x USB OTG, one x4/x2 MIPI CSI-2 input, 2x 3.3V UART, I2C and 4 GPIO”realtimesai.com ↗“Realtimes carrier board for Jetson TX2/TX2i, 1x Ethernet, 2x CAN, -40 to 85 °C, 2x USB”
- Four boards could not be ranked: Diamond Systems Jethro and Ziggy, and Connect Tech Spacely and Cogswell, also support TX2i and are rated to −40 °C, but the catalog lists no weight for them, so I cannot say whether any of them is lighter than the Sprocket. Of those, Spacely is explicitly pitched "for unmanned vehicles" with up to six MIPI cameras and a Pixhawk-ready I/O port — worth a datasheet check if weight numbers from the maker matter to you. Cogswell is end-of-life. diamondsys... +5diamondsystems.com ↗“Jetson TX2/TX2i”diamondsystems.com ↗“Jetson TX2/TX2i”connecttech.com ↗“Jetson TX2/TX2i”connecttech.com ↗“Jetson TX2/TX2i”connecttech.com ↗“Jetson TX2/TX2i carrier for unmanned vehicles that takes up to six MIPI CSI-2 cameras and has a Pixhawk-ready I/O port”connecttech.com ↗“End-of-life.”
- The −40 °C figure is the carrier's rating, and Connect Tech notes on several of these boards that the TX2 module itself is rated −25 °C to +80 °C at the thermal plate. Using a TX2i (rather than TX2) module is the right call for the −40 °C cold end, which is what you're doing. connecttec...connecttech.com ↗“The Jetson TX2 Module is rated for -25°C to +80°C”
