We made the easyC system for faster prototyping and easy connection between the components. However, some of the components have only one easyC port or you just want your cable managmenet made better. What to do in those cases? The easyC hub comes to the rescue! It has six connectors so you can easily expand your circuit. It’s as simple of a device as it can get.

Product usage tips:

You can connect easyC devices to the hub like you would to any other easyC device. Just plug the preferred easyC cable into the hub and a device you’re working with. That’s all there is to it.

You should avoid working with the hub in wet environments to ensure it lasts a long time. Be sure to watch the operating voltage of your circuit. Since the hub works on 3.3V, higher voltages can burn it and render it useless. There is a hole in the middle of the board so it can be secured to any surface.

Product usage tips:

If you encounter errors when using the breakout board, see if it’s connected properly. First, look at the pinout on the board and your microcontroller. If everything seems OK, look at the connections on the breakout board. If all the wiring is correct, make sure that the breakout board’s I2C address is right. It should be 0x70. Everything as it should be so far? Go through your code again. There might be some bugs that are stopping things from working as expected.

The SHTC3 breakout board works wonderfully in combination with Dasduino Core and 16×2 easyC LCD. You can display temperature in one row and humidity in the other.

This logic level converter board module gives us a translation of logic level between two signals. In layman’s terms, if we take a signal with logical “unit” on 5V convert into a signal which logical “unit” has on 3.3V this module will help us. Something like this is useful in this case if we want to achieve communication between two devices from whom one works on 5V and the other on 3.3V, or any other combination of voltages. Directly connecting we would “burn” a device that works on 3.3V and a module gives us to avoid that.
