Grove/Pin Headers I2C 4 Channel Mux Extender/Expander Board for Arduino and Raspberry Pi
Converts one I2C bus (on Pi or Arduino) to 4 separate I2C buses. Expands and Extends I2C busses
Supports Arduino (5.0V I2C) and Raspberry Pi (3.3V I2C). All 4 I2C busses can have 5.0V or 3.3V power.
Has Grove Connectors as well as Pin Headers
Software drivers provided for Arduino and Raspberry Pi
The Grove I2C 4 Channel Mux Breakout Board is a TCA9545A based quad bidirectional I2C Expander and Multiplexor controlled via the I2C bus with GROVE connectors. The SCL/SDA controlling fans out to four downstream channels. It works for both the Arduino and Raspberry Pi. At SwitchDoc Labs, we love data. And we love I2C devices. We like to gather the data using lots of I2C devices on our computers and projects. We are always running into conflicts with addressing on the I2C device. Since there are no standards, sometimes multiple devices will have the same address, such as 0x70 and you are just out of luck in running both of them on the same I2C bus without a lot of jimmy rigging. You can have any combination of 3.3V and 5V I2C busses on this board. What is the solution for this? It's an I2C controlled 4 I2C bus multiplexer! We have both Grove Connectors and traditional pin headers. Grove connectors make it easy to use with no soldering! SwitchDoc Labs is building all future products with Grove connectors and there are many manufacturers of Grove sensors. And we have the software drivers written for it for the Arduino and the Raspberry Pi on github.com/switchdoclabs. With the software and board, you are ready to go!
