DRFduino Mega robotics kit for 4 motors
You wish to build your own mobile robot but you are not an electronics expert? You are looking for a robotics mobile base with plenty of improvement and hack possibilities? The DFRduino Mega robotics kit for 4 motors is for you!
The DFRduino Mega2560 board of the DFRduino Mega robotics kit for 4 motors
Based on the very popular Arduino technology, the DFRduino Mega robotics kit for 4 motors contains a DFRduino Mega2560 board, which is in fact an Arduino Mega2560 board redesigned by DFRobots with colored connectors to easily distinguish between different input-outputs types: red for power, blue for analog input-outputs and green for digital input-outputs.
The expansion shield of the DFRduino Mega robotics kit for 4 motors
The DFRduino Mega robotics kit for 4 motors also contains a Mega IO expansion shield that can be plugged without soldering on the DFRduino Mega2560 board and will allow your mobile robot to communicate with the world: This shield has 3 slots for Xbee, a microSD slot and the connectors allowing to mount another Arduino shield. It also respects the color convention of the DFRduino Mega2560.
The Mega IO expansion shield includes a large prototyping zone and gives you access to the digital pins 14 to 53, the analog pin 6 to 15 and the PWM pins 2 to 9.
The distance sensors of the DFRduino Mega robotics kit for 4 motors
On the sensors side, the DFRduino Mega robotics kit for 4 motors includes four Sharp GP2Y0A21 distance sensors that can detect obstacles at a distance between 10 and 80 cm. Indispensable for your robot to be able to avoid walls.
The motor boards of the DFRduino Mega robotics kit for 4 motors
Finally, the DFRduino Mega robotics kit for 4 motors contains two boards allowing to control two motors each. The 2A Dual motor controllers have high-power H bridges and protecting diodes, as well as a heat sink that dissipates up to 25W.
