M5Stack 1 to 3 HUB extension unit

HUB is a unit used to expand the Grove ports via the M5Stack device. For example, if you want sensors with different I2C addresses or want to output to three devices simultaneously. M5Stack devices can typically output to only one device at a time for a limited number of Grove ports.

Note: HUB is only a hardware expander. If you are looking for hardware and software expanders (standard protocol) like I2C or Single-Bus, please check PaHUB or PbHUB. If you connect two I2C slave devices to a hub that have the same address, you will have trouble receiving I2C data from both. The I2C addresses of the devices must be different. They can be manually changed by altering the resistor values.
