M5 Stack 1 to 3 HUB Unit

Description

M5 Stack 1 to 3 HUB Unit

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 limited amount of grove ports)

Note: HUB is just a hardware expander, if you are looking for a 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 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.

Also check . The unit is a small, single-phase AC relay that can be controlled with a DC signal. It has built-in optocoupler isolation and overcurrent protection.

Package Includes:

1x HUB Unit
