Low-Cost FPGA With Reconfigurable Electronics Feature
Iolinker is a cheap 64 FPGA board with a MachXO FPGA that functions as a dynamically configurable IO matrix. Its main functionality, besides IO extension, is to dynamically set up a matrix of GPIO connections, that allow direct pass-through of high-frequency signals. Circuits can thereby...
