Explorer Board for Dagu Rover5 robot
Including €0.01 for ecotax (not impacted by the discount)
The Explorer PCB for Rover5 offers many useful features in order to develop your very own Dagu Rover5 chassis based mobile robot.
The Explorer PCB consists in many functional blocks allowing powering motors and sensors with multiple voltages but also encoder connectors, motor drivers and battery charger circuitry to use with NiCd and NiMH batteries.
The prototyping pad on the Explorer board allows attaching your favorite control board (Arduino board for example) on your robot and connecting it to all the sensors and actuators of your contraption.
Detailed specifications for the Explorer Board for Rover5 robot chassis
Available output voltages:
- Direct battery voltage: If you are using rechargeable NiMh or NiCd batteries: The 7.2V voltage will be directly available in order to power actuators and sensors and associated circuits.
- Servo power supply: Servomotors usually accept voltages between 4.5 and 6V. This block consisting in several serial diodes will lower the battery voltage and supply the right current toy our servomotors.
- +5V (Vcc): A 1A rated regulator drops the battery voltage to 5V in order to power common components such as sensors.
- +3.3V: Many recent microcontrollers and sensors use a 3.3V voltage. The embedded regulator can provide this voltage.
Motor control circuit:
This functional block offers 2 H-bridges based on FET transistors that can be controlled using a PWM signal (Pulse Width Modulation). This power components are 4A rated and include a current sensor circuit outputting a 1V voltage per amp . using a ADC, it will be possible for you to accurately determine the motors load, torque and stall. Each H-Bridge includes a PWM signal and a direction signal.
If you have a robot chassis equipped with encoder, this socket will allow you reading the encoders value.
Infrared sensors corner connectors
Corner sockets allows the easy connection of infrared proximity sensors. with such sensors, it will be very easy to program your robot to navigate taking in account potential obstacles around it.
V1 and V2 power rails
The Explorer PCB features two easily configurable power rails. using jumpers, you can easily determine the voltage: Battery, Vcc, +5V or +3.3V in order to supply the right voltage to your components.
Battery charging circuit
The Explorer PCB has circuit to enable NiCd or NiMH battery charging. This regulated circuit allows supplying a fixed 9V voltage to the robot batteries.
