Arduino Shield - GPIO extenders

What is a pin extender?

It is a module in the form of a printed circuit board or electronic system that connects to the pins of the Arduino baseboard via the UART, SPI or I2C communication bus, depending on the type Arduino Shield. Why is such a simple tool so popular and so important at the same time? Well, the more pins available, the more we can be tempted to expand our Arduino by connecting more elements and modules to the board. Sometimes it's not about bells and whistles - advanced designs in particular often require multiple components to be connected. It's not worth limiting your creativity and possibilities: don't wait and choose the right pin extender that will allow you to spread your wings and create larger and more complex structures.

Arduino expander - one of the greatest expansions you can imagine

As you already know, the pin expander is an extension of the possibilities in Arduino systems that, thanks to its diversity, will make it easier for you to construct and customize your microcomputer to your own needs. The simplest expander is a board equipped with screw connectors, thanks to which the connection of cables to the inputs and outputs of the main unit becomes much easier and the connection strength is greater. The screw connector module is connected to the main unit through pins led out. If you want to increase the current efficiency of the outputs, it is useful to have a module with relays, which allows you to control devices with a supply voltage of up to 250 VAC and switching currents of up to 15 A. For the latter, you can connect temperature, humidity or pressure sensors and resistors to calibrate each of the measurement channels separately. The pin expander can also handle many interfaces such as SPI (LCD, LED display modules), IIC (ICD display modules, I / O modules), Micro SD, SD, TLC (LED controller).

Pin Expander - unlimited possibilities

If you are a fan of robotics, use the Arduino expander to control drives with motors with 12 V output voltage and current efficiency even above 1 A. If you are building a larger project, use the Arduino Expander to be able to install even more other Arduino overlays (Arduino Shields)!

However, one of the most important advantages of Arduino is the overall flexibility of this system. For example, some products ( for example, Proto Shield) offer you the possibility to create an Arduino shield yourself, perfectly tailored to your needs! Do your expectations go beyond the available Arduino Shield modules? As you can see, this is not a problem at all! Build your own shield, for example the pin expander you need. In our store you can find output expanders in the form of PCBs, which are equipped with all the connectors to connect to the main device. Use the printed circuit board you can create your own Arduino Shield, perfectly adapted to your needs and expectations.
