Expand your I/O with an Octopus!
- 16 Digital Input/Output ports, individually selectable
- 16 PWM outputs
- Up to 8 boards can be stacked, for a total of 128 digital I/O and 128 PWM
- Works through I2C interface
Octopus brings 16 additional digital I/Os per board, with full interrupt support.
It is possible to stack up to 8 Octopus boards, for a total of 128 digital I/Os and 128 PWM outputs.
The supplied Octopus library allows simple usage, quite similar to normal Arduino I/O commands.
Octopus uses just the I2C interface, without requiring any additional I/O. Optionally it can drive an interrupt input using Fishino/Arduino pin 3 or 4.
