What is it?
BerryIMU is an inertial measurement unit, or IMU, that measures and reports on velocity, orientation and gravitational forces, using a combination of an accelerometer, gyroscope and a magnetometer.
IMUs can be found in devices like, quad copters, smart phones, segways, Wii Remote etc.. and are used to sense movement and orientation.
Adding BerryIMU to your Pi will open up a whole new world of possibilities.
BerryIMU is specifically designed for the Raspberry Pi and is designed to take some of the complexity out of IMUs and to try and make them more enjoyable to use. BerryIMU includes the latest and greatest sensor ICs.
BerryIMU is powered off the Raspberry Pi 3.3v pin and is compatible with all Raspberry Pi models.
UPDATE 17th December 2014
Thank you too all our backers!
For those that may have missed out, BerryIMU will be available for purchase after the Kickstarter at;
Stretch Goal $6,500
If this stretch goal is reached, we will add a barometric pressure and temperature sensor (BMP180). The pressure sensor can be use as an altimeter to measure altitude.
- i2c interface
- Measurement range ±245/±500/±2000 dps
- Sensitivity 8.75, 17.50, 70.00 mdps
- i2c interface
- Scales of ±2g / ±4g / ±6g / ±8g / ±16g
- i2c interface
- Magnetic field full scale of ±2 / ±4 / ±8 / ±12 gauss.
- Internal temperature sensor
Why a Kickstarter?
ln order to get BerryIMU in the hands of Raspberry Pi users at a reasonable price, 200+ boards need to be produced.
Documentation and Code
We are aiming to make the use of these sensors fun and enjoyable. We will have documentation explaining the "ins and out" as well as complete code if you just want to jump right in.
We have been working with accelerometers and gyroscopes for over 6 years now. In recent times these sensors are more readily available and at an improved price, however the documentation is still lacking. With BerryIMU we plan to have documentation (and code) available to help users understand how an accelerometer, gyroscope and magnetometer work. In clear and easy to understand guides and examples.
BerryIMU also can sit right on top of your Raspberry PI GPIO pins, no need for any hookup wires.
Mid November 2014
- Launch Kickstarter Campaign.
- End Kickstarter campaign.
- A wait of 2-3 weeks for funds to be transferred from Kickstarter.
- Procure a small batch of PCB and components to confirm quality and functionality.
- Have PCB FAB house create a few assembled BerryIMU to test Fab house assembly processes.
- Submit final order.
- Receive BerryIMUs and perform testing on a few.
- Begin fulfillment.
- Completion of BerryIMUs shipping.
Risks and challenges
For this project, we think the risk we have is the sourcing of the PCB manufacturing and assembly in Hong Kong. To mitigate this risk, we have two Fab houses available for use. And both we have used before. One of which did the PCBs for our last Kickstarter project. (PiScreen)
There is also the risk of delivery delays due to hardware manufacture delays. I have mitigated this by including some padding in the delivery dates. I have also sourced components from multiple suppliers.
This is our second Kickstarter campaign and we have learnt a great deal from our first, so this campaign should be further improvement.Learn about accountability on Kickstarter
