2 Channel Motor + 16 Channel Servo Expansion Board For Arduino UNO Smart Car Chassis Robot Arm
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.
The board can directly be used to control the intelligent robot by Bluetooth (pre-server) and/or WiFi. More detail: https://www.smartarduino.com/
Power for motor(VM): 4.5V-36V, can power separately
Power for servo(VIN): 5V-18V, can power separately
How to use 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.
