IIC TO GPIO module

Having troubles with inadequate digital I/O when using arduino withrobots or interactive media This IIC to I/O modulehelps you solve the problem, Arduino has only two data lines (SCL-Analog PIN5, SDA-Analog PIN4) and IIC can transfer I / O module communication, to convert the 16 digital IO ports, read-write. 8 simultaneous parallel modules, each module can be set to address.

• Module power supply: +5 V
• 16 Digital IO port comes with internal pull-up
• Can be set to eight addresses (address range of 0x20 ~ 0x27)
• 8 modules simultaneously in parallel (IIC bus need to pull together)
• Module Size: 56x53mm (2.21x2.08 in)
