16 CH Motor Control Board - 2 Channel Motor+16 CH Servo Expansion Board For Arduino UNO Smart Car Chassis Robot Arm - RS1459

• Working Current Io: ≤1.2A
• Max power consumption: 4W (T=90℃)
• Input for control signal: High level: 2.3V≤VIH≤VIN; low level:-0.3V≤VIL≤1.5V
• Working temperature: -25℃-+125℃
• Driven mode: double big power H bridge driver
• Weight: about 46g

Description :

• 2 Channel Motor + 16 Channel Servo Drive Shield is compatible with Arduino UNO R3 and ESPduino development board.
• This module can be inserted directly into the Arduino UNO or ESPduino.
• But if using ESPduino, you can develop quickly and conveniently a tank, car chassis controlled by WiFi.
• This driver shield can control 2 Channel DC motor (4.5~18v) and 16 Channel servo (5-18V), which is very suitable for the control of mobile robot with robotic arm.
• This board is designed by using L293DD, which can drive directly 2 Channel DC motor or 1 Channel stepping motor.
• Its max current can be 1.2A.
• 16 Channel servo is controlled by IIC interface on the board.
• The IO interfaces is used as the control interface for Arduino UNO and ESPduino.
• Thus, just the four ports D6, D7, D11, and D12 ( as for ESPduino, it is D12, D13, D3, D1) is defined as PWMB ( speed for motor B), DIRB (the turn direction for motor B) PWMA(speed for motor A), and DIRA( the turn direction for motor B).
• The humanized design is used the power switch, which can make one on/off the power conveniently.

Specification :

• Power for the motor(VM): 4.5V-36V, can power separately
• Power for the servo(VIN): 5V-18V, can power separately

How to use a power connection:

• If short VM and VIN, only can control the motor with 6-18V;
• If short VS and VIN, only can control the servo with 6-18V;
• If short VM and VIN, and short VS and 5V, then CAN control
• the 2 Channel motor (with 6-18V) and 16 Channel 5V servo.
