A low-cost platform for evaluating and developing with the low-power iCE40LP1K FPGA. The board provides access to general-purpose I/O and includes capacitive-touch buttons and LEDs. The board is powered and programmed via USB. An on-board microcontroller enables 2-way communication with the iCE40LP1K FPGA. The free iCEcube2™ development tool controls programming, accesses virtual I/O functions and runs the included demos. The tools can be downloaded from the Lattice website.

An FPGA is a semiconductor device consisting of a matrix of Configurable Logic Blocks (CLBs) connected through programmable interconnects. The user determines these interconnections by programming SRAM. A CLB can be simple (AND, OR gates, etc) or complex (a block of RAM). The FPGA allows changes to be made to a design even after the device is soldered into a PCB.
