樹莓派 Raspberry Pi 8組繼電器擴充板(Mega-IO Expansion Card)
The MEGA-IO is a stackable expansion card for Raspberry Pi B+, 2, 3 and Zero. Two of the Raspberry Pi’s GPIO pins(pin 3 and pin 5) are used for I2C communication. Pins 8 and 10 are used for firmware programming, but are available to the user as GPIO. Pin 7 is allocated for the interrupt handler, leaving 23 GPIO pins available for the user. MEGA-IO adds the following I/O functions:
- Eight on – board relays
- Eight 12 bit A/D inputs
- Eight optically isolated inputs
- One 12 bit DAC Output
- Four open collector outputs
- Six GPIO’s
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.
