SO-101 Leader Arm Electronics Kit

$134.99
SKU: SO-101-LEADER-ELEC

Power and control your SO-101 leader arm with this specialized electronics package based on the LeRobot SO-ARM100 specifications. This kit includes everything needed to operate the leader arm (the arm you physically control): 6 high-torque 7.4V serial bus servos, a 5V regulated power supply, a Serial Bus Servo, and all necessary wiring harnesses and connectors. **Important:** Leader and follower arms require different electronics due to voltage differences. This kit is specifically for the LEADER arm. For the follower arm (with gripper), you need the Follower Arm Electronics Kit which uses 12V servos. The 7.4V servos are optimized for smooth human manipulation. These arms are designed to work seamlessly with the open‑source 🤗 LeRobot library. Perfect for: - Completing your Leader Arm Frame Kit - Building teleoperation systems (pair with follower electronics) - Replacement or upgrade for existing leader arm - Educational robotics demonstrations **Note:** This is specifically for the LEADER arm. For complete teleoperation, you also need the Follower Arm Electronics Kit.

Open-Source Design

This kit is based on SO-ARM100 (LeRobot Project) by Hugging Face and LeRobot Community.
