HUB is a handy expansion unit for GROVE ports on M5Stack devices. It enables you to connect multiple Grove modules to a single M5Stack port—ideal for working with several sensors with different I2C addresses or splitting signals to three different devices at once. Normally, an M5Stack device is limited to controlling one connected Grove module at a time due to its limited number of ports. Note: The HUB provides only physical expansion. If you require both hardware and protocol expansion—such as for I2C or one-wire systems—please refer to PaHUB or PbHUB units, which feature integrated signal switching. Keep in mind: If two I2C devices with identical addresses are connected to the HUB, communication conflicts will occur and data cannot be read from both. To resolve this, ensure each device has a unique I2C address; you may be able to modify the address by adjusting on-device resistors.
