VALUES

Key features

01

Up to 275 TOPS inference

The Jetson AGX Orin 64GB runs large vision-language-action and imitation-learning models on the edge in real time, without cloud dependency.

02

M.2 AI-accelerator expansion

Two M.2 KEY-M slots add low-power AI accelerators such as DeepX or Hailo, or NVMe storage, to match the workload.

03

Integrated robotics connectivity

5x CAN, 6x USB 3.0, GbE, and UART on a single board connect multi-axis actuators and sensors without a separate hub.

04

On-board MCU and sensors

An STM32G474 MCU with power monitoring, IMU, and barometer is integrated on-board, handling navigation, balance, and safety control without extra modules.

SYSTEM

Board composition

Compute, expansion slots, MCU/sensors, and power are integrated on one board, so a robot system runs without external controllers.

Jetson AGX Orin compute

A socketed 64GB module delivers up to 275 TOPS of high-performance AI compute.

M.2 expansion slots

One KEY-E (WiFi/BT) and two KEY-M (NVMe or AI accelerator) slots flexibly expand storage, wireless, and accelerators.

STM32G474 MCU · integrated sensors

A real-time control MCU plus power monitoring, IMU, barometer, LED, and switch are built into the board for low-level control.

Wide-range power · extension board

A DC 20–60V wide input is supported through an extension board over a board-to-board connector, covering varied power environments.
