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, 3.7–4.2V) and delivers fast, precise response from a tiny footprint. Important: this is a 1S servo, so power it from 3.7–4.2V, not the usual 5–6V.

Supplied with servo horn(s).

Wiring & getting started
- Connect power
Brown wire to GND, red wire to a 1S (3.7–4.2V) 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° travel.
- Mind the end stops
Stay within the mechanical range and don't hold it stalled against an end stop.
Common questions
What voltage does it run on?
It's a 1S servo: 3.7–4.2V. 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 (3.7–4.2V) 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. It's a light-duty micro servo for small, lightweight control surfaces and mechanisms, not heavy loads.
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 3.7–4.2V, never 5–6V. Every servo is checked before it ships from our Te Awamutu stock.
