FS90 9g Mini Servo – Addicore
The FS90 mini servo is a lightweight affordable servo ideal for R/C helicopter, plane, and car use, as well as other mechatronic projects using controllers like Arduino and Raspberry Pi.
The FS90 is a 9 g analog servo from FEETECH (formerly known as Fitec) which is similar in form and function to the Towerpro SG90.
The specifications state that this servo has a 120° operating angle for standard servo pulses between 900 µs and 2100 µs.
As with most servos, the pulse range can be expanded to achieve an expanded operating angle, but the limits of which are not specified by FEETECH.
