Servo Lineup

Model	Interface	Size (mm)	Weight	Voltage	Torque @ 8.4 V	Speed @ 8.4 V
C12204-001	PWM	23 × 12 × 27.5	21 g	3.6–10 V	5.3 kg·cm	0.07 s/60°
C12204-002	PWM	23 × 12 × 27.5	21 g	3.6–10 V	5.3 kg·cm	0.07 s/60°

All current models use a coreless brushed motor, full metal gear train and full metal case.

Choosing an interface

PWM

One or two servos driven by an RC receiver, flight controller or a timer output. Nothing to configure. See PWM control.

Serial bus (UART / RS-485)

Three or more joints. One cable daisy-chains every servo, and you can read back position, current, voltage and temperature. See the UART bus protocol.

Sizing torque

Leave at least 100 % headroom over the calculated load, and size from the torque at the voltage your supply delivers under load, not its nominal rating. More in the FAQ.
