Extend the functionality of your systems with the iolinker FPGA IO Interface Board. Compatible with Arduino, Raspberry Pi, and PC, this is the ultimate interface. You can use the iolinker FPGA boards to rewire and self-test your circuitry totally. The chainable IO extender comes pre-programmed to handle your systems. With the IO-linking feature, you can connect your devices, LCD, keypad, LEDs, and more to the GPIO. This compact yet powerful system saves you time in rewiring so you can focus on creating. In addition, the iolinker helps you to test and verify your systems before they go live. Additionally, the iolinker can detect and notify you of errors. With simple software changes, you can hang on to your hardware and be more efficient than ever before.
