1/2/4pcs Feetech FS90R 360 Degree Continuous Rotation Micro Robot Servo Wheel

About this deal

The Feetech FS90R is a micro servo built specifically for continuous rotation, making it a straightforward and affordable way to get a small robot moving. It weighs just 9g and measures 23.2 x 12.5 x 22mm, operating on 4.8V to 6V with an analogue control system. At 6V it reaches up to 130RPM and delivers up to 1.5kg.cm of torque. Available in packs of 1, 2 or 4 units. It is well suited to microcontroller platforms such as the BBC micro:bit, Arduino, Raspberry Pi and PICAXE. It is a good choice for beginners who want to make things move without building a motor controller with feedback and gearbox, and its compact size means it fits into tight spaces. Unlike a standard servo, this unit is static at a 1.5ms pulse, with a longer pulse giving forward rotation and a shorter pulse giving reverse rotation -- and a small trimmer pot lets you fine-tune the stop point. Servo horns and attachment screws are included.
