Electrical System

Review the K1 compute module, communication interfaces, power system, and board-level components here. PCB files, MCU firmware, and wiring documents will be shared separately.


Compute

K1 uses the NVIDIA® Jetson Orin™ NX 16GB module for robot-side computation. This compute stack supports control, perception, learning workflows, and deployment of trained policies on the robot.
