DESCRIPTION
The FEETECH HLS3604M / HL-3604-C001 is a compact 360° digital micro servo designed for dexterous robot hands, compact robotic joints, robotic grippers, and other space-constrained robotics applications.
With a compact 20 × 11.4 × 24.4 mm aluminum housing, the servo delivers up to 4.4 kg·cm torque at 6V while weighing only approximately 12.5 g.
It features a coreless motor, metal gears, TTL serial communication, 360° position control, and real-time feedback for load, position, speed, current, input voltage, and temperature. Its compact size makes it particularly suitable for multi-joint robotic hands and other applications where size and weight are critical.
