Feetech Bus Servo Cables, 3-Pin 5264 Connectors, for STS3215 / SO-ARM101 / LeKiwi, 15–90 cm, 5-Packs and Mixed Set
Couldn't load pickup availability
These are 3-pin bus servo cables with 5264 (2.5 mm) female connectors on both ends, wired the way Feetech STS/SCS servos require, used to daisy-chain the servos of SO-ARM101, LeKiwi and OpenDuck robots and to connect the first servo to the adapter board.
Genuine Feetech 3-pin bus servo cables with 5264 connectors, the exact type that links STS3215 servos in the SO-ARM101, LeKiwi and OpenDuck. Keep a set on the bench: a chafed or too-short joint cable is the most common reason a LeRobot arm drops a servo ID mid-recording.
What can you use it for?
- Replacing a damaged joint cable in an SO-ARM101 / SO-101 arm
- Wiring a new arm from loose servos (the mixed pack covers one arm)
- Longer 40 / 90 cm runs from the base servo to a controller mounted elsewhere
- LeKiwi base wheels and OpenDuck legs
Who is it for?
Anyone assembling or repairing Feetech-servo robots who wants the correct connector and lengths instead of generic Dupont jumpers.

Frequently asked questions
Which lengths does an SO-ARM101 arm use?
Hiwonder's kit ships 3 × 100 mm, 5 × 160 mm and 7 × 200 mm cables per arm. Our 15 cm replaces the 100 mm and 160 mm positions, 20 cm the 200 mm positions; the mixed 12-pack rewires one arm with spares.
Are these reverse-wired?
Yes. Feetech bus cables are wired 1-to-1 so that both connectors carry the same signal, ground and power pins; these match the cables that come with the servos.
Can I cut and splice them?
Yes, they are 26 AWG silicone-insulated wires, but a clean connector-to-connector cable is more reliable in a joint that flexes thousands of times per dataset.
