STS3215 is 7.4V 19kg serial bus smart servo，adopt plastic case、core motor、metal gearbox、Feetech self researched and developed TTL control board，12 bit high precision magnetic coding sensor. The stall torque is 19kg.cm，can achieve 0-360 degrees any angle controllable，multi-turn continuous operation mode, it can realize the function of setting the middle point with one key，acceleration slow start and slow stop，can feedback position、speed、voltage、current、temperature、load parameters，thus, overload and over-current protection can be realized. It is suitable for application in industrial equipment, robot and Small torque drive application scenarios.
