Criteria for Selection
Before diving into the top contenders, let’s explore the essential factors that define a high-quality Raspberry Pi Model 2 touchscreen. Understanding these criteria will empower you to make an informed decision and choose the display that best aligns with your project requirements.
Several characteristics set apart high quality display from those that are lacking. First, there are different display size options available. The best choice will be dictated by the size constraints of your project. You also have to consider the resolution to determine how crisp and detailed the images will look.
Next, you will have to consider the connection between your display and the RPi2. Options include HDMI, SPI, and I2C. Each having their own pros and cons. Compatibility with the Raspberry Pi Model 2 is a given, but it’s worth checking to ensure proper operation and driver support.
Touch technology, resistive or capacitive, is something to be considered as well. Resistive touchscreens are generally more affordable and work with any stylus, while capacitive touchscreens offer superior responsiveness and multi-touch capabilities.
Power consumption plays a significant role in portable or battery-powered projects. Lower power consumption extends battery life and reduces heat generation. Pricing is always an issue, so make sure you find a touchscreen that has a solid price/performance ratio. Finally, research the user reviews and community feedback to learn about the real-world performance and reliability of each touchscreen. This is a great way to uncover any potential issues or hidden benefits.
