GERUI 2 PCS TCA9548A IIC Multiplexer Breakout Board 1.8V 5V 8 Channel I2C Communication Switch Development Expansion with Arduino

[Interface] There are 8 I2C interfaces on 1 expander, equipped with 8 bi-directional switches, which can be controlled via the I2C bus. This means that after 1 expander is connected, 8 devices with the same address can be connected to the same I2C port and used normally. Operating voltage: 1.8V - 5V. Clock frequency: 0 - 400 kHz. [Default Address] The default address of this expander is 0x70, the address can be changed and set between 0x70 and 0x77 as needed. [Features] 8 expanders can be cascaded within the address 0x70~0x77, and each expander can be connected to 8 devices with the same address, realizing that the same I2C interface is connected to 64 devices with the same address and normal use. [Compatible] Compatible with IIC bus and system management bus, active low reset input, support for hot insertion, low standby current. No glitch pulse when power on, support voltage between 1.8V, 2.5V, 3.3V and 5V bus flat conversion.
