Raspberry Pi can be both a programming learning device and an element of electrical installation or building automation. External devices allow us to modify the purpose and capabilities of the minicomputer freely. All of this is due to GPIO connectors, which we use to connect compatible external accessories to Raspberry. As a result, advanced controllers with an interface that is complemented by buttons and LCD display are created. This versatility of the Raspberry Pi is one of the reasons why the computer enjoys unflagging popularity and interest since its first appearance on the market. This event took place in 2012. Since then, the manufacturer has developed several Raspberry Pi models, which differ in terms of parameters, application and additional elements, so they have more or less extensive features. Below we present the offer of HAT overlays and GPIO connectors. Discover what benefits you can gain from them and how your Raspberry Pi will change when you use them.
Fingerboard is equipped with a USB connector for Raspberry Pi Zero. After installing the pads on the device, it can be connected directly to the computer or HUB " without any additional cables and power source. Trim is compatible with the Raspberry Pi, Zero, and Zero V.
Cover for Raspberry Pi Zero / Zero based on a STM32 microcontroller with 12-bit ADC Converter, with the Grove connectors for connection of sensors and modules from the Grove, interacting through the interface digital, analog, I2C, PWM, UART. Currently, more than 60 modules Grove supported the imposition Grove Base Hat.
Overlay designed for the Raspberry Pi, Zero, performing the function of emergency power in case of loss of utility power. The module is compatible with other versions of the Raspberry Pi. UPS HAT is transferred to the device over a period of time that will allow You to keep the essential elements and safely shut down the system.
Mark NB-IoT for Raspberry Pi that allows you to create calls in the GSM network. Supports communication protocols such as LWM2M/COAP/MQTT. Communication via serial interface UART (RX, TX) using the AT command.
High-quality sound card with speaker, digital-to-analog and analog-to-digital for the Raspberry Pi 4B/3B+/3B. Equipped with a Converter Burr-Brown 192 kHz / 24-bit. On the Board there are two gold-plated RCA connectors and one connector mini Jack 3.5 mm. the Tiles can be extended with DSP. The module mounts directly on the GPIO pins of the Raspberry Pi.
Driver dual DC motor TB6612FNG operating with a supply voltage from 7 V to 12 V and DC 1.2 A per channel and momentary 2 A. the Module in the form of overlays for the Raspberry Pi communicates through an I2C interface.
Lora IoT Gateway is a wrapper for the Raspberry Pi that allows you to create access gateway for Laura, compatible with The Network Thing. Lora Gateway is part LoRaWAN, the device receives packets with Laura Nodes and provides mechanical compensation in LoRaWAN. Works with a frequency of 868 MHz.
Overlay for Raspberry Pi is equipped with a sensor of temperature, pressure and humidity BME280, light sensor and proximity LTR-559, analog gas sensor MICS6814, Converter ADC ADS1015, a MEMS microphone and a color LCD display. The Board also has a connector for the sensor PMS5003.
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.
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!
