The FRIDB realizes an experimental platform for RFID (13.56 MHz). It consists of an Antenna, a ST Micro M24LR64 RFID-Tag Chip with EEPROM port and a Texas Instruments TRF7960 RFID reader chip with SPI interface.
So you can make the Freerunner either a RFID tag (e.g. to open doors) or a RFID reader (to read/write standard tags e.g. in credit card format).
The board comes with three parts that can/must be separated:
Either the Tag or the Reader module fits into the area above the SIM/SD card reader of the Openmoko Freerunner. It is up to you to wire the board to the Freerunner main board in a way that you can still swap SD cards and/or SIM cards.
The FRIDB can also connected to other Microcontrollers and SoC (e.g BeagleBoard) since it has splitted I/O and power supply.
The supply voltage as well as the SPI / I2C bus is routed to testpads at the end of the board.

Schematic and board layout files are available in CadSoft EAGLE 5.x format from http://projects.goldelico.com/p/fridb/downloads/.
The best way to connect the FRIDB to your Freerunner is to solder four wires to...
