Manufacturer profile
FEETECH
Shenzhen servo manufacturer whose ST/SC bus-servo families are widely specified in open-source robot arm and mobile-platform BOMs.
Identity boundary
Profile, not endorsement.
RCI links the manufacturer identity to public evidence. Inclusion does not imply independent verification of performance, commercial availability in every region, or any commercial relationship with RCI.

These checks define the evidence work still required; they are not claims about this manufacturer.
A
Motion & Actuation
- Separate continuous, peak and stall output
- Preserve duty cycle, thermal and cooling conditions
- Resolve gearing, backlash, encoder and brake boundaries
- Pin voltage, firmware and communication variant

TTL networked smart servo actuatoractive
ST-3215-C001
This record freezes the 7.4 V-class variant ST-3215-C001 of the STS3215 family and preserves the official page’s voltage wording exactly: the title and description market the servo as “7.4V 19KG”, while the specification table states an operating voltage range of 6-7.4V and attaches its only stall-torque figure, 19.5kg.cm, to 6V. RCI does not resolve this internal tension (documented voltage-conflict note RCI 049). The 12 V variant ST-3215-C018 is a separate record.
TTL networked smart servo actuatoractive
ST-3215-C018
This record freezes the 12 V-class variant ST-3215-C018 of the STS3215 family as a separate record from the 7.4 V-class ST-3215-C001, demonstrating the variant-split rule. The official page markets the servo as “12V 30KG” while its specification table states an operating voltage range of 4-14V; RCI preserves both statements without resolving them.
