Butterstick FPGA Development Board

The ButterStick is an FPGA development board. Building off the OrangeCrab, the Butterstick's primary focus is exposing lots of fast I/O pins. To achieve this goal it makes use of the SYZYGY peripheral connector standard. The board features High-speed USB and Gigabit Ethernet for high-speed input/output to a computer. Additionally there is 256MB (2Gbits) of onboard DDR3L memory. The development board makes use of the ECP5 FPGA from Lattice which is fully compatible with the open-source FPGA synthesis flow.
