The Amani 64 is a low-cost entry-level CPLD development kit, stackable with the Arduino, other Amanis, and Arduino-compatible shields. The Amani 64 can relieve the Arduino of time-intensive processing functions passing the Arduino data as needed. Data can be transferred via SPI, a parallel data transfers, or an interface of your own invention. Perform both combinatorial and sequential functions faster and with more available I/O while freeing up the Arduino for other tasks. All Amani I/O is configurable to be active I/O or passive pin thus allowing the programmer to use Arduino pins to interface with the Amani, to external devices, or both.

Theoretically uses all the pins and none of them: all the CPLD pins are broken out to either the Arduino pins or the extra headers on the shield. Actual use depends on the way the CPLD has been configured.
