Universal 16-bit GPIO Daughter Card for the Fm+ Development Board

The OM13489 allows one to evaluate almost all of NXP’s 16-bit I²C GPIO Expander portfolio using the Fm+ Development Board and GUI. Pinout differences between devices are handled via jumpers and power supplies can provided by the development board or via an external power supply. No test device is mounted on the board, however a TSSOP24 footprint is provided allowing the user to solder the device he’s interested in onto the board. Connectors allow direct connection to the Fm+ Development Board and the TotalPhase Beagle. The I/O pins of the GPIO Expander may be directly observed and driven using a direct connection to the OM13303 GPIO Target Board.
