Everything you need to be up and running with a Geekduino and Sensor shield I/O break out board to mount to your projects.
The Robotgeek Sensor Shield breaks out the digital and analog pins into easy to use 3-pin connectors. Each connector supplies 5 volts, ground, and a signal pin. These connectors can easily be connected to RobotGeek Sensors
as well as a wide variety of sensors, actuators and output boards.
Voltage Switchable PWM Channels
The Arduino does a great job of controlling PWM/RC Servos, making them ideal for a variety of robotic projects. But sometimes powering these servos can be a problem. Powering servos off of the Arduino's 5v regulator leads to underpowered servos, limited by the Arduino's built in regulator. With other sensor systems, connecting a servo to an external power supply requires multiple cables or boards, defeating the purpose of a sensor shield. The RobotGeek Sensor Shield solves this problem with 2 jumpers to control the output voltage of the 6 PWM channels on the Arduino. Just move the jumper from '5V' to 'Vin' and your servo will start to draw power from your Arduino's input voltage supply. And since there's 1 jumper for each 3 PWM channels, you still have the flexibility to add a variety of sensors to your project.
