Reconfigurable electronics, and less mess with jumper cables? Need a chainable UART / SPI / I2C IO extender with LOTS of pins? Is it okay if it can output PWM signals as well?
The iolinker FPGA board connects any two pins (signals up to 29.56 MHz) for you, on the fly. Ideal for prototyping, self-testing and designs with many IOs.
Developing time critical embedded software and prototyping embedded solutions a lot -- sometimes with custom PCBs, sometimes without -- I noticed how much time is wasted rewiring digital signals in prototype setups; and in companies, it is costly, too, often wasting time of both a software and a hardware engineer simultaneously.
I wanted a solution that simplifies plug'n'play designs, creates flexibility and keeps my wiring in software -- version controlled. This FPGA project has been on my mind for years, and now I got some help to make it come true.
This is a preprogrammed, low-cost Lattice FPGA board + Arduino adapter.
