DFRobot (DFR0576) Multiplexer Board, Digital, 1-to-8, I2C, Gravity

DFR0576 is a Gravity: digital 1-to-8 I2C multiplexer board. This I2C multiplexeris easy to use, plug and plug and no need to weld. 1 multiplexer has 8 I2Cports, this means you can hook up 8 same-address devices at the same I2C port by1 multiplexer. The default I2C address of the multiplexer is 0x70, and you canadjust from 0x70 to 0x77. In theory, you could hook up 8 multiplexers on address0x70~0x77 to control 64 same-address devices. So powerful.Specifications:- Accessory Type: Digital 1-to-8 I2C Multiplexer Board- For Use With: Arduino Board- Kit Contents: Gravity Digital 1-to-8 I2C Multiplexer, Gravity 4 Pin UART/I2CCable, XH2.54 - 5 Pin Header- 3.3 to 5V wide operating voltage- On-board I2C address dial switch, the I2C address can be set- Support the cascade of 8 multiplexer on address 0x70~0x77- 4pin color-coded headers, simple and clear- PH2.0-4P connector type- High 3.3V, low 0V interface level- I2C interface protocol and I2C clock rate is 100K, 400K- Dimension is 32 x 32mm / 1.26 x 1.26in
