Good for making remote for tracked Rover v2!

Great foundation for controlling tracked vehicle Rover. Implemented with Android Nexus 7 to make remote control. Eventually I will use to switch between remote control and autonomous navigation. Hope to be able to send picture files to PC and Nexus 7

Very good card

Works perfectly (tested between Arduino and Android). Beautiful product. Very well documented.

Excellent module, will by another

An excellent bluetooth module. Works right out of the box but can also be reconfigured as needed. Will need this program to do so: Read the datasheet provided by robotshop


I am a rookie so it took some time to figure out the bt module. That being said, it works perfectly and a more experienced person would have had it up and running within minutes.

Excellent peace of kit

I am new to robotics at 62 but I found it easy with this peace of kit . Everything I have purchased has worked out of the box, just keep it coming and make it nice and simple for me . your's robotic Roy.
