If you are a Raspberry Pi lover and enjoys building IoT (Internet of Things) projects using your Pi device, then you must be interested in the new Raspberry Pi HAT. The Raspberry Pi HAT (Hardware Attached on Top) is specifically developed for the Raspberry Pi and IoT range of PCs. If you are an owner of the Raspberry Pi Zero, then you will certainly in need of this to get the most out of your device.
Why is IoT HAT preferable than other options?
The Raspberry Pi IoT HAT is an add-on board which provides Wi-Fi and Bluetooth connectivity for your Raspberry Pi device. Of course, you can use USB dongles for the Bluetooth and Wi-Fi, but the Pi HAT is more affordable. Because you get the features of both at the cost of one dongle.
The Raspberry Pi 3 is another great option for this because it comes with inbuilt Bluetooth and WiFi. But if you have to deal with the current consumption or you are making a smaller sized project, then the combination of the Raspberry Pi Zero and this Pi IoT HAT is a perfect choice.
What IoT HAT for Raspberry Pi has?
The IoT HAT is equipped with Bluetooth 4.1 and Wi-Fi with 802.11n wireless standards. It offers dual mode support and can be added to any Raspberry Pi mini PC with the included 40 pins GPIO connector. The wireless technologies of IoT HAT allow you to connect a wireless keyboard, access the internet and do much more.
If you own the Raspberry Pi Zero, then you need some things as under to use IoT HAT:
One USB OTG cable to connect a USB device to the micro USB port of Pi Zero
If you want to connect multiple USB devices, then you should buy a USB hub with power adapter
With which Raspberry Pi models, the IoT HAT can be used?
Not only the Raspberry Pi Zero, but the IoT HAT can also be used with the Raspberry Pi Model A+, B+, and the Raspberry Pi 2 model B. The IoT HAT uses the same BCM43438 chip that is used in the Raspberry Pi 3. You can also add an antenna to improve the Wi-Fi signal, which is not possible with the Raspberry Pi 3 having an inbuilt WiFi functionality.
Is it worth to get the IoT HAT?
The Raspberry Pi Zero IoT HAT has a current consumption of 230mA. It is available for just $14. While the Raspberry Pi 3 (Which is generally not useful for the projects where minimum size is preferred or where the power is not the factor to take care) consumes current of 320mA and costs nearly $35. If you use a Raspberry Pi 2 with a USB WiFi and USB Bluetooth functions, it will consume 350mA of current. So, it the best option to get the IoT HAT for smaller designed projects and where power is not the key factor.
The IoT HAT fits on the top of the Raspberry Pi device and does not compromise with the form factor of the Pi model. All the factors are seamlessly integrated between IoT HAT and Raspberry Pi. Don’t wait, get your IoT HAT for the Raspberry Pi and make awesome projects with low cost and smaller scale designs.
