The Icepi Zero is an FPGA development board in the popular Raspberry Pi Zero form factor. It carries a Lattice ECP5 25F, enabling powerful designs while keeping a small portable size. It also has a GPDI mini (General Purpose Display Interface, same as the one on the Pi Zero) port allowing easy digital video output.
