## Description

From robot arms to remote control planes, this servo is perfect for moving light objects.

If you have used similar 9g servos in past projects you'll love the upgrade to an official Feetech FS90, the template for third-party copies.

The FS90 is a PWM-driven servo so most dev boards and single-board computers are able to drive them with no changes to hardware, check out our guides for [Raspberry Pi](https://core-electronics.com.au/guides/control-servo-raspberry-pi/) and [Arduino](https://core-electronics.com.au/guides/servo-control-with-arduino/). But if you want to get fancy check out the [PiicoDev Servo Driver](https://core-electronics.com.au/piicodev-servo-driver.html), the driver board handles all of the PWM control, just send a command via the I2C bus!

### Examples

#### Raspberry Pi Pico - Micropython

 ```
import machine
import utime

pwm1 = machine.PWM(machine.Pin(0))
pwm1.freq(50)

min_s = 1300
max_s = 8500

mid_p = int((max_s - min_s)/2)

def map_range(x, in_min, in_max, out_min, out_max):
    mapped = (x - in_min) * (out_max - out_min) / (in_max - in_min) + out_min
    return int(max(min(mapped, out_max), out_min))

def servo_wrapper(val):
    return map_range(val, 0, 180, 1500, 8000)

# Useful while attaching servo horns
# or finding the zero-point for continuous servos

# while True: 
#     pwm1.duty_u16(mid_p)

while True:    
    for i in range(0,180,10):
        print('Angle/Speed ', i)
        pwm1.duty_u16(servo_wrapper(i))
        utime.sleep(0.2)
        
    for i in range(180,0,-10):
        print('Angle/Speed ', i)
        pwm1.duty_u16(servo_wrapper(i))
        utime.sleep(0.2)
```
