DIY C300 Aluminum Alloy Metal Wheel Car Chassis For Arduino NodeMCUThere are six kinds for your choice:A: Gold ChassisB: Gold Chassis + Espduino kitC: Gold Chassis + NodeMcu Lua kitD: Silver ChassisE: Silver Chassis + Espduino kitF: Silver Chassis + NodeMcu Lua kitIntroduction: A novel design has already coming for the tank chassis、 with beautiful shape、 and full metal aluminum alloy structure. In this tank chassis、 a space for 9g servo is left for the ultrasonic sensor、 and a space for MG995 servo is also left to rotate the mechanical manipulator. What's more、 UNO R3 and NodeMCU development boards are also designed to install. In addition、 the metal panel can be used to install the wheeled car by install the 25mm and\/or 37mm motor frames. Interesting、 a LED light is installed to brighten the dark in the night. Under the help of the motor、 the tank chassis can be smoothly turn left、 right、 circle、 forward and backward、 ect. Therefore、 when you get the chassis、 it can do many things for you、 like getting the temperature and mobile monitor. Certainly、 we have developed a series of car\/tank chassis. Hoping you can choose your loved car chassis.Specifications:Name: C300 Intelligent car chassisMaterial: aluminum alloyWheel: Rubber (has blue and red colors.)Product size: about 200*120*70mmMotor Parameters: Name: 25mm gear motorOutput speed: 150±10%rpmNo_load current: 200mA (Max)Stall current: 4500mA(max)Stall torque: 9.5kgNaNRated speed: 100±10%rpmRated torque: 3000gNaNRated current: 1200mA (Max)Noise :56dBWorking voltage: 9VOutside Shaft Length: 14.5mmShaft End Play: 0.05-0.50mmScrew Size: M3.0Diameter Of Shaft phi 4mm、 D3.5Encoder: 2pulses\/circleNote:This is DIY kit and unassemble kit.
