We can also find an SD card slot where we can store files and images to display on the screen. The board also features an ESP32 microcontroller with integrated Wi-Fi and Bluetooth connectivity. I like it, we can build projects which can last on battery for months.

This board can achieve a deep sleep current of 18μΑs. Since the display uses the E-Ink technology, it only consumes power when it refreshes its contents, so if we don’t update the display all the time we have almost zero power consumption. It offers a resolution of 600x448 pixels and the refresh rate of the screen is about 11 seconds. White, Black, Red, Yellow, Blue, Green and Orange. This display can display 7 different colors. It is the first time I use a color E-Ink display and I love it. So, let’s see what this board offers.įirst of all this board uses a big Color E-Ink display. A board that will contain everything I would ever need to build a project and that it will be easy to work with. I have built many projects in this channel using an e-ink display. If you are not familiar with it, an e-ink display uses electricity only when it updates its contents, so even though this device is now off, it still displays this image.

I have been making things for over a decade now, and I am fascinated by e-ink technology and its uses. This is a 6” color E-Paper display board. But that's a topic for another Instructable. We can take these values and, using a specific algorithm, the Zambretti algorithm, generate our own weather forecast. The last bar graph is the most useful of them all, in my opinion. A line graph that shows the temperature readings of the last 24 hours, a bar graph that shows the humidity readings of the last 24 hours, and a bar graph that shows the barometric pressure readings of the last 24 hours. We get the temperature, humidity, and barometric pressure from two sensors, and the weather forecast from the internet. On the display, we show the temperature, humidity, barometric pressure, and weather forecast. Among all the e-paper boards I've used in the past six years, this is the best.

Let me show you how I built this project and how you can build your own using the same or a similar display.įirst of all, let me explain what this project is and how it works.Īs you can see, we have a large, 6-inch E-Paper display that can display 7 colors combined with an ESP32 microprocessor. The reason for this is the amazing E-Paper display it uses. I've built many weather station projects in the past, but this one is different. I've finally made it and I am really excited– a battery-powered weather station project. This is a project I've wanted to build for over a decade now.
