The Sequent Microsystems Mega-IO Expansion Card for Raspberry Pi/Zero is a stackable expansion card for Raspberry Pi B+, 2, 3 and Zero. Two of the Raspberry Pi’s GPIO pins are used for I2C communication. Another pin is allocated for the interrupt handler, leaving 23 GPIO pins available for the user. Up to four MEGA-IO cards can be stacked on top of a Raspberry Pi. Any of the inputs of the MEGA-IO can be configured as interrupt inputs.
The top 40 pin header plugs into the Raspberry Pi GPIO header and passed through the pins to the next MEGA-IO expansion card. The bottom 40 pin header is a right-angle connector for I/O expansion. The eight Relays are numbered from upper left to lower right. Numbering the Relays is important to associate them correctly with the Relay Headers and Relay LEDs. The Relays are SPST, with three output pins labeled COM, NO and NC.
