9 degrees freedom $56 with AVR codebase



This is an interesting board - perhaps most interesting is the approach to driver-based sensors in the datasheets.

good news!does it possible to use it for multiwii?

The ITG-3200 and BMA150 are well known

but never heard something about the AK8975 (compass).

Anyway.., the price is really good

Titeuf007: Probably since multiwii already supports the ITG-3200 and the BMA150 but im not sure whether the sensors go through a   second processor or if they are directly interfaced

No processor, the I2C lines and 3 IRQ out are available direct at the connector

They are already known and integrated in multiwii, and I launched a group buy for EU people here:


52Euro including shipping in EU

AK8975 magnetometer is in my LG phone which is not exactly a good thing, 8-bit ADC :/

Hi Hamish,


Thanks for the Info. Knowing this details I think I will take a 'FreeImu'


higher price but better parts.
