Product Description: Tank chassis with a holder containing two metal Servo, a mg996r steering gear, a mg946r Servo gripper can swarmed Raise with two bearings to withstand greater force. Chassis bracket and gear train are all-metal build, solid and stable, dual-motor power traction (brushless motor imports, all-metal gear, with Hall speed sensor), powerful, run fast and smooth, high stability, forward and backward, Zuozhuanyouzhuan, standing around, turning flexible features, but which at the bottom of the chassis for the customer to install the control circuit to provide enough space, and the chassis has a stand below the platform, customers can use to install the battery, the rear chassis may installation circuit. Motor signal definition: White line: DC motor drive voltage (Note motor voltage range is very wide, 3v-12v, generally do not share the same path and encoder supply) Black line: DC motor drive voltage (Note motor voltage range is very wide, 3v-12v, generally do not share the same path and encoder supply Blue: power positive encoder (3.5-6v, if and microcontroller IO connection, use 5v, note that on the supply must be regulated) Green line: code output, note the NPN open-drain, pull-up resistor to the encoder positive power supply, such as 1k resistor. Red Line: encoder negative power supply (ground) The encoder uses three lines, motors with two lines from the encoder and the motor is electrically isolated physically. The relationship between them is the tail of the motor magnet and Hall switch linking.
