Feetech HL-3606 6V 6kg.cm 360° Metal Gear TTL Serial Bus Servo

The Feetech HL-3606 is a compact TTL serial bus smart servo with an aluminium case, coreless motor and copper-and-steel gear train, producing 6kg.cm of stall torque at 6V. Multiple servos share one half-duplex serial bus, each with its own ID, which keeps wiring simple in small robot arms, pan-tilt heads, grippers and multi-joint builds.

Key features

• Two versions: C001 with a single output shaft, or C002 with a double shaft for supporting a bracket on both sides of a joint

• 360° position range with 4096-step resolution (0.088°) and PID position control

• Bus IDs 0–253 at 38400bps to 1Mbps

It is commanded by digital packets rather than PWM, so drive it from a serial bus servo adapter or a microcontroller UART wired for half-duplex, not from an RC receiver or a flight controller's PWM outputs.
