Grove - I2C Hub (6 Port)
Grove - I2C Hub (6 Port) is an I2C expansion interface board, compared with the old Grove - I2C Hub, the same size, two more connectors, almost half the price!
Overview
We've already released the Grove - I2C Hub (4 Port), now comes the 6 port version, the same size, two more connectors, almost half the price!
As you may know, the 7 address length I2C bus allows up to 128 I2C devices to access.
At present, there are over 80 Grove I2C modules in Seeed, however, normally only 1 or 2 Grove I2C connectors are available on the Seeeduino Board or the Grove Base Shield. What if we need to use multi Grove I2C modules in the system? The answer is Grove - I2C Hub (6 Port).
There are 6 Grove connectors in this hub, one input, five output, or you can even connect one hub with another, so that more devices can be plugged in.
Not only I2C but also can be used to control several synchronous change devices (like LEDs).
We did a survey and gathered some feedback about the old Grove I2C Hub (4 Port), many users mentioned that the 4 slots are not sufficient, so we add two more and keep the same 20*40mm size.
SeeedStudio always values the voice of our customers, and we appreciate our customers helping us grow and make us better.

If you need a device which draws a certain amount of current and power for testing, then GreatScott! has just the solution. His project uses an Arduino Nano, along with a separate IC and a voltage divider, to measure both current and voltage input from the power source. It then employs this data to properly adjust a MOSFET, dissipating the correct amount of voltage and power as required. Interface is handled via a rotary encoder and a 16x2 I2C LCD display, and the electronics are housed in a solid-looking enclosure. As seen in the video below, the adjustable constant load features an impressively large heat sink, needed to take care of the 30V and 20A that the setup is capable of drawing.
