Some questions regarding MiniQ 2WD Complete Kit (Based on Arduino)

userHead limhanchung 2012-05-30 22:08:45 10817 Views9 Replies
Hello

I am interested in the MiniQ 2WD Complete Kit (Based on Arduino) and would like to ask some questions about it:
1. Can I use the RN-XV Wifly Module to control it using wifi? And do I need anything extra apart from the module?
2. Can I remove the battery holder and replace it with a lithium polymer battery instead?
3. Is it still in stock?

Thanks

I think maybe our 2WD MiniQ might not be the right platform for you. It has no spare data pins for the compass.


I think maybe the 4WD MiniQ might be a better option. It includes some jumper for you to disable some things like the buttons and you can use the A4 and A5 pins to drive the compass through I2C. You will need an additional Xbee/USB adapter to mount the Xbee on the 4WD miniQ.

For my project I need to use both xbee and compass, although for xbee there is a separate slot but
how can I connect "CMPS10" compass to the board?

This kit has an Xbee slot where you can directly plugin an xbee.


Could you give me more details about the compass you plan to use? Do you know what kind of data it is using? how many and what kind of pins does it need?


Please keep in mind that this kit is limited in I/O pins, so you might not be able to connect the compass. Please check the schematic for available pins.

On the 2WD MiniQ you can only use 1 form of serial communications at a time. So you can only use the Wifly, or xbee module, or unplug these modules in order to program the miniQ through USB.


This is due to the on board Arduino which only supports 1 Serial port. You could emulate a second serial port through the use of 2 digital pins and the software serial library. But this emulated serial port is not as fast, and you could have some sync problems between your wireless devices.


If you just need a micrcontroller that has more than one communications port I recommend a DFRduino MEGA which has 4 Serial ports.

2012-06-01 00:43:26 Hi,


You can just click on the "notify me" button and the system will automatically notify you when the item is back in stock. It will probably do a better job than me. I often don't realize when items are re-stocked.

2012-06-01 00:04:15 Thank you. Keep me informed on when it come back in stock. userHeadPic limhanchung
2012-05-31 20:08:51 1. You should be able to use it with the WiFly module, you will need a PC or some other wifi enabled device to communicate with it.
2. You can remove the battery hold, it is provided for convenience. Just make sure you provide the right amount of voltage.
3. We do not have it in stock at this moment. I'm not sure when it will be in stock again. I think it will be back in stock in about 1 or 2 months. Sorry :(
