The AGFRC C02CLS is an ultra-light 2.2g coreless digital sub-micro servo, built for small RC aircraft, helicopters and micro robotics where every gram matters. It runs on a single LiPo cell (1S, 3.6–4.2V) and delivers fast, precise response from a tiny footprint. Important: this is a 1S servo, so power it from 3.6–4.2V, not the usual 5–6V.

Wiring & getting started
- Connect power
Brown wire to GND, red wire to a 1S (3.6–4.2V) supply. Do not use 5V.
- Connect signal
Orange wire to a PWM pin on your Arduino or ESP32 (3.3V or 5V logic are both fine).
- Use the Servo library
On Arduino use Servo (ESP32Servo on an ESP32); writeMicroseconds() gives fine control over the ~120° operating travel.
- Mind the end stops
Standard operating travel is ~120°, but the mechanical limit is 180°. Never hold it stalled against the hard stop, and avoid driving it with extended pulse widths that push past the 180° limit.
Common questions
What voltage does it run on?
It's a 1S servo: 3.6–4.2V. Don't feed it 5V, that's above its rating and can damage it. Use a single LiPo cell, or a buck converter set to around 4V.
Can I power it from an Arduino's 5V pin?
No, 5V exceeds its 4.2V limit. Power it from a separate 1S (3.6–4.2V) source with a common ground to your controller. The signal wire can still be 3.3V or 5V.
Will it work with Arduino and ESP32?
Yes. It takes a standard PWM signal, use the Servo library on Arduino, or the ESP32Servo library on an ESP32.
How much can it move?
Around 0.11kg·cm of torque. Under standard PWM (900–2100µs) it sweeps ~120°±10° of operating travel. The gear train's hard mechanical stop is 180° — don't drive it past that with extended pulse widths, and don't hold it stalled against the stop.
How is it wired?
Standard 3-wire servo lead: brown is ground, red is positive (the middle wire), and orange is the signal.
Good to know: This is a 1S servo, always power it from 3.6–4.2V, never 5–6V. Every servo is checked before it ships from our Te Awamutu stock.
