Specification Brand : Rakstore BulletPoint1 : This module is the 16 way IO extension module of the 12C interface, and built in the MCP23017 chip of MicroChip. BulletPoint2 : Each IO can be arbitrarily configured as input or output, and a pull up resistor can be set, and the interrupt function can be enabled for the IO configured as input. The IO interface has a strong driving capacity, and the current and current can reach 25mA. BulletPoint3 : MCP23017 is a high-speed IIC interface. It supports the IIC frequency of 100KHz, 400KHz and 1.7MHz. The chip has 3 address pins, which can be set up for 8 different addresses. So 8 modules can be connected through two IIC buses to achieve up to 128 IO extensions. BulletPoint4 : This module is flexible in configuration and strong in driving ability. There are many parallel connections. BulletPoint5 : Working voltage:3.0-5.5V,Working current: 1uA,IIC communication frequency: maximum 1.7MHZ ExternallyAssignedProductIdentifier1 : 0794304673793 ExternallyAssignedProductIdentifier2 : 794304673793 ItemName : Rakstore MCP23017 I2C Interface 16-Channel IO Extension Module IIC Expansion Board ItemPackageDimensions_Height : 1 centimeters ItemPackageDimensions_Length : 11 centimeters ItemPackageDimensions_Width : 7 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : io-modules Manufacturer : Rakstore Material : lead ModelNumber : 1734-IE2V-NEW NumberOfBoxes : 1 NumberOfItems : 1 PartNumber : 1866 Platform : not_machine_specific ProductDescription : 1734-IE2V Analog Input Module I/O 2 Channels 1734IE2V New in Box with Warranty ProductSiteLaunchDate : 2021-08-06T04:59:42.996Z SupplierDeclaredDgHzRegulation : unknown SystemBusStandardSupported : SATA 2 UnspscCode : 43201500
