Sale price £7.30 incl. VAT excl. VAT

The HUB is a unit used to expand the GROVE ports over the M5Stack device. For example, if we wanted 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 a limited amount of grove ports)

Note: The HUB is just a hardware expander, if you are looking for a hardware and software (standard protocol) expander like I2C, or 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 a 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.
