Description Seeed Studio reComputer J2021 is a compact edge AI computer built around the NVIDIA Jetson Xavier NX 8GB production module. It delivers up to 21 TOPS of AI performance in a hand-size enclosure, making it a strong fit for computer vision, AI video analytics, machine vision, and embedded edge inference projects that need Xavier NX performance in a ready-to-deploy full system. Unlike a carrier board, reComputer J2021 is a complete system with the Jetson Xavier NX 8GB module, enclosure, heatsink with fan, carrier board, and pre-installed JetPack 5.1.1. It is useful when you want a practical Xavier NX 8GB deployment platform instead of assembling a board-level solution from separate parts. reComputer J2021 also gives you a balanced mix of AI compute and expansion, including 4 x USB 3.1, HDMI, DisplayPort, 2 x CSI, M.2 Key E, M.2 Key M, CAN, RTC, and a 40-pin header. That makes it suitable for edge AI terminals, smart cameras, robotics prototypes, and Xavier NX based application development. Features Jetson Xavier NX 8GB based edge AI computer with up to 21 TOPS AI performance. Pre-installed JetPack 5.1.1 so the system is ready to power on and start developing. Compact full system with carrier board, enclosure, cooling, and Xavier NX module already integrated. Rich I/O: 4 x USB 3.1 Type-A, 1 x USB Type-C device mode, Gigabit Ethernet, HDMI, and DP. 2 x CSI camera connectors for machine vision and AI camera projects. M.2 Key E, M.2 Key M, CAN, RTC, and 40-pin GPIO for expansion. Wall-mountable compact enclosure for edge deployment in tighter spaces. Strong Xavier NX 8GB platform for AMR, AI video analytics, and machine vision applications.

Product List Acrylic Cover 1 x Aluminium Frame 1 x Jetson Xavier NX module 1 x Aluminum heatsink with fan 1 x Carrier board 1 x 12V/5A (Barrel Jack 5.5/2.5mm) Power Adapter (Power cable not included) 1 x Other Content reComputer J2021 is a full Jetson Xavier NX 8GB edge AI computer, not just a base board. That means you get a finished deployment platform with enclosure, cooling, carrier board, and module already integrated, which helps shorten bring-up time for edge AI, machine vision, and robotics projects. Power-on ready workflow: the system comes with JetPack 5.1.1 pre-installed, so teams can move faster on validation, model testing, and interface bring-up. If you need more memory in the same family, you can compare it with reComputer J2022. If you want to see the older higher-memory reference model, you can also compare it with reComputer J2012. Important accessory note: the package includes the 12V/5A power adapter, but it does not include a power cord, and it does not include the 3V RTC battery. If you are comparing the broader series, the reComputer collection is a good place to review related Jetson systems.
