Great, but would recommend having some experience with Arduino robot I have built a number of how do we know based robots. I was looking for something to reduce all of the extra components such as motor shields and the like. This suited my purpose very well. I am not sure, how a novice in robot building would be able to use this. Having a little experience, it is a piece of cake.

Purchase and delivery was good, however after many hours of research, following all directions, downloading software both Windows 10, and Arduino IDE drivers, I cannot get this device to connect... as is the device is useless. I was unable to find DFRobot support.

On the surface, this appears to be a great board. It has many outstanding features like the row of three male pins for each female pin from D0 through D13. This makes it very easy to plug female connection wires into the board. It also has six programmable buttons and external power for the servo motors. It has a built in motor control that uses only two pins per motor to manage and takes motor power from an external header.The board is based on the Arduino Leonardo rather than the UNO which provides an extra 512K of SRAM. This can be critical for complex applications.Normally I would give this five stars but I knocked it down for several reasons:1) Although the documentation is excellent, the customer support appears to be non-existent. Several attempts to contact them with questions went into the great bit-bucket in the sky.2) The primary USB connection is a micro USB connector which I have found can be easily damaged. For this board, I would have greatly preferred a regular USB connector.3) There is no provision for external power except through the servo and motor headers. This means I cannot plugin a 9V power supply while testing.4) I had repeated problems uploading the sketch to the board. I think there is something slightly flaky about the programmer for this board, but I have no hard data to support this.5) The pins used to drive the motors clash with the pins used to power the DF Robot (same maker) LCD Keyboard Shield. This means that I cannot use the shield to display data on the status of the system. I have not yet attempted to make this work, but preliminary queries are not hopeful.If DF Robot can make the motor pins configurable so that it can work with the LCD Keyboard shield, that would be a HUGE improvement.

I really liked using these while they actually worked!! But after the first run it stopped being recognized as a device. All signs pointed to the romeo malfunctioning. I purchased another one and the same problem happened, except this time it never worked. I received two duds, but the seller gave me a refund for both so I was able to quickly buy an Arduino for my project. I wish I would've been fortunate enough to use the Romeo, because while it worked my project was much easier.

The Romeo is grate for just about any RC/robot project. all pins are nicely broken out with power, and shields can steal be implemented. Leonardo based, so no removing the xbee for programming. though i have not use the on board buttons, they can easily be used for menu functions. the on board 2x2A motor controller is grate. save space on an over all project. This is a good MPU from some one just beginning to the pro. i have two Romeos running my spy tanks. no problems.
