Overview

WoMaster, a Taiwanese industrial AIoT innovator, has launched the WTK Series — a family of fanless NVIDIA Jetson Orin edge AI computers purpose-built for smart manufacturing, machine vision, robotics, and smart city infrastructure. The WTK-3821T runs the Jetson Orin NX in 16GB (100 TOPS) or 8GB (70 TOPS) configurations, while the WTK-3721T is built on Jetson Orin Nano with 8GB (40 TOPS) or 4GB (20 TOPS) options.

Both platforms feature a compact, fanless design with DIN-rail or wall-mount options, wide-temperature operation, and flexible 9–30VDC power input. Rich I/O includes dual Gigabit LAN, four USB 3.0 ports, HDMI, RS232/RS485 serial, CAN Bus, and isolated DIO — plus expansion for 5G, 4G LTE, and Wi-Fi modules.

Pre-installed with NVIDIA JetPack 6.2, the WTK Series supports the full NVIDIA AI software stack — TensorFlow, PyTorch, DeepStream, TensorRT, Caffe, and PaddlePaddle — with integrated NVIDIA Isaac ROS for robotics development. This makes the WTK Series an accessible, industrial-grade entry point for companies deploying AI at the edge without compromising on ruggedness or software maturity.
