Product Description 3V Digital Micro Servo, Standard (FT90B) Overview: Do you need little standard servos for a little mechanical project? Try this compact, lightweight servo that requires only 3V to operate, making it great accessory for the BBC micro:bit! It is an ideal servo motor for micro:bit GO bundle projects paired with our I/O adapter to bring both micro:bit control signals and direct battery current right to a breadboard. A 3-pin single-row header, available separately, will come in handy for connecting this servo to a breadboard. This servo is included in the What’s a Microcontroller with Python and micro:bit – Complete Kit. Control this servo with PWM (pulse width modulation) signals. It accepts 500-2500 µs pulses, and a 1500 µs pulse will make it turn to and hold its neutral position in the center of its 180° range. 3V Digital Micro Servo, Standard (FT90B) Features: Operates at just 3V, ideal for two 1.5V batteries Easy to control with simple PWM (pulse-width modulation) signals Rotates to and holds any position in a 180° range Set of servo horns is included Applications: Adding motion to micro:bit projects Animating a mechanical character Raising or lowering a signal flag Opening or closing an access hatch 3V Digital Micro Servo, Standard (FT90B) Specifications: Operating voltage: 3V to 4.8V DC Communication: PWM, 500-2500 µs Neutral position: 1500 /- 45 µs Angle limit: 180° No-load speed: 0.16 s/60° @ 3V, 0.12s/60° @ 4.8V No-load current: 75mA @ 3V, 100 mA @ 4.8V Idle current: 4 mA @ 3V, 5 mA @ 4.8V Stall current: 400 mA @ 3V, 700 mA @ 4.8V Torque: 1.0 kg-cm (13.9 oz-in) @3V, 1.3 kg-cm (18.1 oz-in) @ 4.8V Operating temp range: -4 to 158 (-20 to 70 °C) Gear material: Plastic Case material: ABS Spline: 21 T, 4.8 mm Dimensions: 32.3 x 12.1 x 30.7 mm Weight: 9 g
