DIY Robot Car Chassis Kit Drive controller module: Chip: L298N Maximum power: 20W Drive voltage VMS: +5V ~ +30V Drive current: 2A(MAX single Bridge) Logic voltage Vss: +5VÔΩûԺã7V (+5V can be taken from the board) Logic current: 0ÔΩû36mA Control signal input voltage range (IN1 IN2 IN3 IN4) Dimensions: 43x43x27mm DC Motor: Voltage: 3V ~ 6V Maximum Torque: 800gf cm min (3V) No-load Speed: 1: 48 (3V time) The Load Current: 70mA (250mA MAX) (3V) With EMC, It Has An Anti-interference ability Package: 2* L298N Module 4* DC Motor 4* Car Tire(size: Diameter 67mm/2.6", Width 27mm/1.06") 20 x 20CM Jumper Wire female to female 20 x 20CM Jumper Wire Male to Male 20 x 20CM Jumper Wire Male to Female TAKE A NOTICE: (1)Be careful not to let the motor get stuck during use. The stuck motor will instantly increase the current through the motor to more than 2A, which will cause damage to the motor. (2)The module is equipped with AMS1117-5.0 LDO bottom linear voltage regulator chip. The minimum input 6V from the outside can output a stable 5V voltage. The current provided is about 300MA, which can only be used by the single-chip system and some low-current sensors, such as Infrared, ultrasonic, etc. cannot be used with steering gear or stepper motor, otherwise it may cause damage to the voltage regulator chip. (3)can not be used to drive stepper motors, it will cause burnout, only good for small motors. (4)Pay attention to heat dissipation during use, and do not directly touch the module during work to prevent burns. This set of products uses high-quality materials, is safe and portable, has strong driving force, and is easy to install and operate. It is the best choice for you to get started learning to make creative projects, do experiments, make smart cars, and mechanical tool toys.
