PSF-B85 has completed self-contained wireless network, with built-in 32-bit kernel processor, on-chip SRAM, it can be used as the main control chip, but also as a WiFi adapter. Simply apply it to other microcontroller-based designs by SPI/SDIO or I2C/UART interface communication....
power header, and "ICSP" (SPI) header are all in equivalent locations. Further the main UART (serial port) is located on the same pins (0 and 1). Please note that I2C is not located on the same pins on the Due (20 and 21) as the Duemilanove / Diecimila (analog inputs 4 and 5...
