![]() I used the push buttons ‘A’ and ‘B’ to control the brightness of the backlight of the display. The Display HAT Mini makes for a great IoT or home automation display. This data can be obtained from an online weather forecast server, there are plenty of those that offer free access. ![]() On the internet I had found a collection of nice-looking weather icons, and so I decided to create a weather forecast display in Python3 showing the corresponding weather icon together with temperature, atmospheric pressure, humidity, and wind direction and speed. With the display up and running, I wanted to do something with it. After installing the libraries, all the examples worked without a hitch. I plugged the Display Mini HAT on a Raspberry Pi Zero 2 W running Buster and controlled it over SSH. Examples for using the display with Pygame and PIL are provided too. Detailed instructions on how to do this are given in their GitHub corner. To use the Display HAT Mini on a Raspberry Pi you must install a library. Both headers provide access to the I 2C bus. I suspect that they were placed that way to provide some extra mechanical support for the display.Įven though the HAT blocks access to the 40-pin HAT connector, extensions are still possible thanks to either the Qw/ST (Qwiic/STEMMA QT) connector and the so-called Breakout Garden header. The push buttons are placed very close to the display, making them a bit difficult to use. To me, these stand-offs are too high, 8.5 mm would have been much better (but non-standard).īesides the display, the HAT also features four tactile buttons and an RGB LED. The display comes with two 10-mm-high stand-offs and four little screws (five in my case). Mounted on a Raspberry Pi Zero without stand-offs, the total height is approx. ![]() The display’s resolution is 320 by 240 pixels (3:2), which corresponds to about 200 PPI (pixels per inch). ![]() The Display HAT Mini also has four tactile buttons and an RGB LED. It is intended for the Raspberry Pi Zero and Zero 2 W but, as it has the standard 40-pin HAT connector, it can be plugged on any Raspberry Pi equipped with such a connector if you are careful as the HAT’s I 2C connector (‘Breakout Garden header’) collides with the Raspberry Pi’s Display connector. The Display HAT Mini from Pimoroni is equipped with a rectangular 2.0” diameter IPS (In-Plane Switching) LCD with SPI interface. ![]()
