The world's only 3D position/inertia sensor over BluetoothLE
Hello Netizens! I wanted to get the word out about something never before done: IMU data (3D XYZ position and movement tracking) with temp and barometer readings, over Bluetooth Low Energy!
(3V @ 16MHz)
I've been building the earlier prototypes by hand, and in conjunction with the Femtoduino boards, I've hand built about 2,000 boards to date. (Parts are smaller than poppy seeds)
I simply could not keep staying awake till 6am every day to ship stuff out fast enough, ...so I've launched this Kickstarter to get IMUduino fabricated locally, and shipped quickly.
If you want to build Drones, map stuff without GPS, build Smart Home devices, or wearable...using PhoneGap and Arduino, then I invite you to have a look. I've added sample code as well.

- opless 12y agoWell done! :-)
- pkinsky 12y agoVery cool! >Another interesting feature: You can build apps for the IMUduino using HTML and JavaScript thanks to PhoneGap or Cordova and our sample app! PhoneGap supports Arduino now?!? Or do you provide a cordova plugin that can communicate with the board via BLE? If so, what platforms do you support?
- femtoduino 12y agoWe are leveraging a Bluetooth Cordova plugin to access the smart device's Bluetooth Low Energy features. We subscribe to the nRF8001's UART service, sending and receiving 20 bytes of data at a time.
- moron4hire 12y agoWhat's the maximum sampling frequency? What are the accuracy and precision like? How susceptible is it to changes in the weather? I'm asking seriously, because I could severely use a module like this (actually, the BLE is not a concern), but haven't found anything suitable in an attractive price range.
- femtoduino 12y agoThe onboard barometer has a 10cm precision, but the 10-DoF IMU is incredibly accurate. The IMU components originate from the FreeIMU, uses for DIY drones and copters.
- femtoduino 12y ago...I am able to send data about every 200ms or so. I haven't weather tested it yet, but the ATMega32u4 is fairly robust. With practical weather proofing and vent ports, this board should last reasonably well in an average environment. As with any electronics, humidity and temp control factor into its life expectancy. We just got out of beta, so I don't have weather proofing tests to show for it. :-)
- moron4hire 12y agoI'm not worried about weather proofing, I'm worried about the sensors going out of calibration under minor changes in temperature, humidity, and barometric pressure.
