9g Micro Servo - FS90 (180 degree, 1.5kg/cm)
Easily add motion to your projects with the FS90, the staple Maker servo.
In stock, ships same business day if ordered before 2PM
Delivered by Fri, 15th of Nov
Quantity Discounts:
- 6-50 $4.44 (exc GST)
- 50+ $4.10 (exc GST)
Recommended Essentials:
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 and Arduino. But if you want to get fancy check out the PiicoDev Servo Driver, 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)

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))

return map_range(val, 0, 180, 1500, 8000)
# Useful while attaching servo horns

while True:
