Additional Hardware
Compass
The HMC5843 compass from honeywell seems as if it would be a simple addition, if it could be wired onto a I2C bus..
Gyroscope
The forthcoming invensense itg3200 is a gyroscope chip that could similarly be connected to a I2C bus.
Debug ports
Under the battery are several groups of test pad connectors. With the camera on the left, and the battery removed. These are numbered for the purposes of this page clockwise, with pad 1 of a connector at its top left.
Probable connections are anything that will enable full tests and bootstrap of of the phone without a case.
Obvious candidates are JTAG for flashing any bootloader, and USB for flashing the device. Serial ports, I2C, SPI are also possible.
- J1 - 2 pad connector to the middle left above the battery connector.
- J2 14 pad connector in two parts.
- (a) - 6 pad connector.
- (b) - 8 pad connector
