128 Channel USB GPIO Module - 128-channel IO expander with USB communication

KAmod I2C-Mini Out8 enables easy expansion of microprocessor systems with eight switching outputs for voltages and currents typical of low-voltage load control. Compatibility with the I2C bus and the ability to connect up to 8 modules in a single network make it an ideal solution for automation systems, lighting and power control, and other applications requiring flexible control of multiple circuits.
