M5STACK BN 2306308 Operating instructions

  • I have reviewed the product details for the M5Stack GROVE Expander HUB UNIT. This unit expands the number of GROVE ports on your M5Stack device, allowing you to use multiple sensors or devices. The document details its function and some important considerations, especially regarding I2C address conflicts. I'm ready to answer your questions about the device.
  • What is the HUB unit used for?
    Can I connect multiple I2C devices with the same address?
    Is the HUB an hardware and software expander?

M5Stack HUB UNIT
Specification

HUB is a unit that is used in order to expand the GROVE ports over the
M5Stack device. For example, if we want sensors with different I2C
addresses or output to 3 devices at the same time. (M5Stack device
usually can output one device at a time to to limited amount of grove
ports)
Notice: HUB is just a hardware expander, if you are looking for hardware
and software (standard protocol) expander like I2C, Single-bus, please
check PaHUB or PbHUB.
If you are connecting two I2C slave devices onto HUB that share the
same address, you will have problem getting I2C data from both. The I2C
addresses of the devices must be different, they can be changed
manually by changing the resistor values.
