Below is a brief technical summary of the new boards/modules
- 4 MPU9150 9-axis IMUs sampled in parallel
- Atmel AT32UC3C2512C 32-bit floating point microcontroller
- ST SPBT2632C2A Bluetooth module
- Battery powered with charging via USB
- 4 layer 22.5x20x5.5mm PCB (excluding protruding USB connector)
- Module size, including 150mAh battery, circa 31x24x14mm (casing not final)
In addition we have also thrown in a flash memory (up to 64Mb) and a pessure sensor.
If you have looked at the photos below you may be wondering why there are two micro-USB connectors. The one which has a slot in the casing is a proper USB used for communication (if you don’t want to use the Bluetooth or simply want more data than the Bluetooth-link can handle), charging, and reprogramming with the bootloader. The one hidden inside the casing actually contains a JTAG interface for debugging and reprogramming. Micro-USB connectors are simply convenient small footprint connectors.
