This set includes a BWT901CL gyroscope as a remote control. This accelerometer gyroscope can control the servos to rotate to different angles, so as to control X, Y, Z axis movement of the robot arm.

  • 【Motion control】With BWT901CL accelerometer gyroscope, the robotic arm can be controlled by your hand.
  • 【Servo control】4-axis robotic arm is controlled by MG995 and SG90 servos
  • 【Programmable】it is programmed via Arduino micro-controller. We provide basic testing code, and you also can writer your own codes and make it unique for yourselves.

BWT901CL accelerometer gyroscope:
  • Chip: MPU9250
  • Input voltage: 3V-6V 
  • Consumption current: typical 20mA 
  • Volume: 25.4mm X 25.4mm 
  • Measuring : Attitude angle: 3 axis Acceleration: 3 Axis Angular Velocity: 3 Axis Magnetic 
  • Range: Acceleration: ± 16g, angular velocity: ± 2000 ° / s. 
  • The data output frequency can reach 200Hz 
  • Data Interface:Serial port of bluetooth, Serial (TTL level), I2C . 
  • Baud rate (baud rate deault 115200kps). 
  • Provide single-chip analytical sample code. 
  • With GPS connectivity. Acceptable in line with NMEA-0183 standard GPS data 
  • 4 way expansion port for analog input and digital input and output 
Note:Angle of Z axis will be accurate because of adding magnetic field correction .Requiring the magnetic unaffected.
