reComputer J202 is a high-performance, interface-rich NVIDIA Jetson Nano / Xavier NX / TX2 NX compatible carrier board, providing HDMI 2.0, Gigabit Ethernet, USB3.1, M.2 key E wifi / BT, M.2 key M, CSI camera, CAN, GPIO, I2C, I2S, Fan, and other rich peripheral interfaces. There is an additional power adapter included.
Functionality
With the NVIDIA Jetson module assembled, it could support NVIDIA JetPack, which includes a board support package (BSP), Linux OS, NVIDIA CUDA®, cuDNN, and TensorRT™ software libraries for deep learning, computer vision, GPU computing, multimedia processing, and much more.
With its multiple camera connectors, it is suitable for running multiple neural networks in parallel for applications like image classification, object detection, segmentation, and speech processing.
Highlighted Features
- Perfectly suited: Design for Jetson Nano/Xavier NX/TX2 NX (260-pin SODIMM).
- Developer Kit carrier board alternative: 1:1 matches the size and nearly the same functional design as the carrier board of Nvidia’s official Jetson Xavier NX Developer Kit.
- Rich peripherals: Higher performance stability consists of USB 3.1 ports(4x), M.2 key E for WIFI, M.2 Key M for SSD, RTC, CAN, Raspberry Pi GPIO 40-pin, and so on.
- High versatility: Suitable for complicated AI graphical applications.
- Comprehensive certificates: FCC, CE, RoHS(Certification received in early Sept)
