MESA 7C81 is FPGA motherboard host for a Raspberry Pi CPU. The 7C81
connects to the RPI's GPIO interface and uses SPI for FPGA communication.Three 26 pin header connectors with standard
parallel port pinouts and 5V tolerant I/O are provided for
compatibility with most parallel port interfaced motion control /
CNC breakout cards/ multi axis step motor drives, including Mesa's 25 pin daughtercards. Mesa's 25 pin
daughtercards or standard parallel port breakout boards allow almost
unlimited I/O options including quadrature or absolute
encoder inputs, step/dir (to 10 MHz) or PWM/dir outputs, and field I/O expansion to
hundreds of I/O points. In
addition to the parallel expansion ports, the 7C81 provides two
RS-422/RS-485 interfaces for I/O expansion via serial I/O
daughtercards. The 7C81 mounts in standard 107 mm DIN rail channels and is powered by 5V
