Product Description
5PCS TCA9548A Expansion Board I2C IIC Multiplexer Breakout Board 8 Channel Expansion Board
About This Item
Introducing the 5PCS TCA9548A Expansion Board I2C IIC Multiplexer Breakout Board - the perfect solution for connecting multiple identical I2C devices to your main control board! This versatile expansion board allows you to easily communicate and use up to 8 same-address I2C devices with just one microcontroller. With the TCA9548A Multiplexer Breakout Board, you can eliminate the hassle of dealing with multiple devices with the same address. Acting as a gatekeeper, this multiplexer shuttles commands to the selected set of I2C pins, ensuring smooth communication and usage.
Changing the address on this expander is a breeze, and you can set it within the range of 0x70 to 0x77, depending on your specific needs. In theory, you can cascade up to 8 expanders in the address range of 0x70 to 0x77, allowing you to connect 64 devices with the same address and use them simultaneously. Designed to be compatible with both the IIC bus and system management bus (SMBus), this expansion board features an active low reset input, support for hot insertion, low standby current, and glitch-free power-up.
It also supports voltage levels between 1.8V, 2.5V, 3.3V, and 5V, making it versatile and suitable for various systems. To make usage a snap, we have put this nice chip on a breakout board complete with capacitors, pull-ups, and pull-downs. With some header soldered in, you can easily plug it into a solderless breadboard.
Package Includes: - 5 x TCA9548A I2C IIC Multiplexer Breakout Board Expand your I2C capabilities with the 5PCS TCA9548A Expansion Board I2C IIC Multiplexer Breakout Board. Order yours today and unlock the full potential of your microcontroller!.
