TCA9548A 1-to-8 I2C Multiplexer Breakout Module, 8 Channels, 3.3-5V, for Arduino

TCA9548 TCA9548A 1 To 8 I2C 8-channel IIC Multi-channel Multiplexer Breakout Module for Arduino Development Expansion Board Product Description: TCA9548 is an eight channel (bidirectional) I2C multi-channel expansion board module that allows a single host I2C bus to control eight independent I2C devices, enabling communication between multiple I2C devices with the same address. The module can be programmed and used through the microcontroller I2C interface, and can switch between eight different addresses. Product parameters Working voltage: 3.3V-5V Communication interface: I2C interface There are 8 I2C interfaces on one expander, and there are eight bidirectional transfer switches that can be controlled by I2C bus. This means that after 1 expander is transferred, 8 identical addresses can be connected to the same I2C port. The device is also in normal use. The default address of this expander is 0x70, the address can be changed, and can be set within 0x70~0x77 according to your needs. In theory, 8 expanders can be cascaded in the address of 0x70~0x77, and each expander can connect 8 devices with the same address. This realizes the same I2C port and connects 64 devices with the same address and uses them normally. Very powerful! Compatible with IIC bus and system management bus (SMBus), active low reset input, support for hot insertion, low standby current, no glitch during power-up, support for voltages between 1.8V, 2.5V, 3.3V and 5V buses Level shifting.
