Overview
The LOGi-Pi is the first FPGA development platform that has been optimized for use with the Raspberry Pi. The
LOGi-Pi adds FPGA flexibility and capability that allows the Raspberry Pi to be easily morphed into endless digital
applications. The FPGA/CPU combination the LOGi-Pi creates an incredibly powerful and versatile digital canvas
for users to create their imaginative digital designs.
