SeeedStudio Grove 8 Channel I2C Hub (TCA9548A)

We’ve already released the Grove – I2C Hub (4 Port) and the Grove – I2C Hub (6 Port). Wait, still not enough? Well well, we know you are seeking more. Here you are, we present you the Grove – 8 Channel I2C Hub.

More importantly, this is more than just a superposition of port quantities. As we all know, I2C devices must use different addresses in the same bus system, even use the Grove I2C Hub (4 or 6 port), the rule is still the rule. However, with the help of  Grove – 8 Channel I2C Hub, you can plug up to 8 same-address I2C devices to the same Grove I2C system. All thanks to the TCA9548A I2C Multiplexer Chip. It adopts time-division multiplexing technology so that the same controller can control 8 I2C devices with the same address. No more worrying about address conflicts.
