Description
The FEETECH HLS2915M is a compact TTL serial bus servo designed for robot joints, robotic arms, quadruped robots, hexapod robots, and other compact motion-control systems.
It features a 360° magnetic encoder, metal gear transmission, TTL serial bus communication, and a compact 34 × 20 × 23 mm body. The servo supports continuous position feedback and is suitable for applications requiring closed-loop joint control in a small form factor.
Two versions are available. The HL-2915-C001 uses a coreless motor and provides up to 14.2 kg·cm torque at 12V, while the lighter HL-2915-C002 uses a core motor and provides up to 8.9 kg·cm torque at 12V.

FAQ
What is the difference between HL-2915-C001 and HL-2915-C002?
The C001 version uses a coreless motor and provides 14.2 kg·cm torque at 12V with a no-load speed of 110 RPM. The C002 uses a core motor and provides 8.9 kg·cm torque with a no-load speed of 77 RPM.
Does the HLS2915M support 360° position feedback?
Yes. It uses a magnetic encoder and supports a 360° position range represented by 0–4095.
Is this a standard PWM RC servo?
No. This model is designed around TTL serial bus communication and is intended primarily for robotics and programmable motion-control applications.
Can it be used for robot joints?
Yes. Its compact dimensions, metal gearing, magnetic encoder and serial bus interface make it suitable for robotic arms, quadrupeds, hexapods and other compact robotic joints.
