What are HAT overlays, and what is their purpose?

HAT overlays are rectangular boards with dimensions of 65mm x 56mm. They are distinguished by rounded corners, as well as holes for fixing them to the case. In addition, the HAT overlay has a 40-pin GPIO connector that is compatible with Raspberry Pi. Automatic system configuration is possible with ID_SD and ID_SC pins. They connect via the I2C interface to the EEPROM memory, which contains configuration software on all GPIO pins, but also Device Tree files. These files are necessary for automatic software installation via Linux because they contain a description of a HAT board.

Our shop offers HAT overlays in different variants, which allows us to match them to a specific version of Raspberry Pi, both the latest and older ones, which are still used by many users. This way, you can be sure that the overlay is compatible with the device, and thus the whole thing will work smoothly and safely.

What should you know about the GPIO extension?

GPIO, which is actually General Purpose Input Output, is the basic parameter of Raspberry Pi. Digital GPO pins have two statuses, i.e. ON and OFF, sometimes also have a receiving direction. If we know and use the appropriate programming language, such as JavaScript or Python, we can control their direction and status. GPIOs are designed to operate at a voltage of 3.3 V, and the maximum current load is 16 mA. So we can power up to two LEDs from a single pin. However, we will need external components in this case, which already uses more power.

GPIO connects Raspberry Pi with Hat overlays. The 40-pin connector allows you to connect external devices, with it you can transmit the output signals needed to control external processes. It is also needed to receive input signals. GPIO extensions, which take the form of HAT overlays, allow you to use Raspberry Pi in many areas of your life. They give you the opportunity to create a LED lighting controller, which is today considered not only the most energy-efficient light source but also the smartest, of course, if we connect it with the controllers. HAT overlays also support the creation of meteorological stations with sensors of temperature, precipitation, wind speed and other weather parameters. We will also use GPIO extensions in designing, among others, drivers for electric gate motor. GPIO extension has also found its application in monitoring and irrigation systems. This means that Raspberry Pi is perfectly suited for modern smart construction. All this thanks to HAT overlays and GPIO extensions.

Create a sound system in your car, a home monitoring system, a weather station or simply improve your everyday comfort with smart lighting. Check our offer of HAT overlays!
