DFRobot Mega IO Expansion Shield for Arduino MEGA

I have used the DFRobot Mega IO Expansion Shield for several Arduino projects. Seems to be good quality, and works as advertised. The "Wiki" information page is a bit sparse, but more-or-less provides the info you need. Also the price seems to be a bargain.

I actually got v2.3 of this shield from RoboShop. I'm using it with an Arduino Mega ADK board on my robot, called W.A.L.T.E.R. 2.0 now. It has all the three-pin headers I need for sensors, separate headers for the UARTs, and I2C, plus headers for an XBee device on three of the UARTs. I couldn't have asked for more! If you are using an Arduino Mega (or ADK) for a robotics or process control application, you need this shield!

Really handy for simply wiring sensors and other modules. No need to build a turntable to power the hardware or be limited by shields or each connector "monopolize" 2 I / O. (on UNO) The possibility of being able to use an external power supply is also a not insignificant. I have not tried the Ports Bee and SD yet but for now it's great. (Soon I test the Bee).

Hatte bei den anderen Sensor Shields das Problem dass das Ethernet Shield nicht funktionierte (fehlender SPI Anschluss). Mit diesen Shield ist das kein Problem mehr und alles funktioniert. Die PWM Anschlüsse sind zwar verdeckt aber wenn man die Ethernet Shield Anschlüsse verlängert ist auch das kein Problem mehr. Mit diesen Shield spart man Geld und Platz. EINFACH TOP. Bestellvorgang-Zahlung-Lieferung auch ohne Probleme.

It has all you need to complete your Arduino Mega for complex projects. Go for it!
