Many supply higher brightness (luminance) measured in candela per square meter ( cd/m²), a unit which is often referred to as a nit. Several of the screens offer backlighting, extra-wide viewing angles, and higher contrast ratios. Most Raspberry Pi touch-panel systems feature capacitive touch, which is generally preferred as being more precise than resistive technology. Most of these systems provide industrial-friendly wide-range power supplies, and some offer opto-isolated interfaces, surge and EMC protection, and UPS. Some offer extended temperature support, and one of the systems covered here includes IP65 ingress protection. Purpose-built industrial touch-panel system add additional features such as wall-mounting kits and in some cases, VESA or DIN-rail mounting. (Here’s an Instructibles how-to on flush mounting the official RPi touchscreen on a wall.) There are also numerous smaller screen options that are generally more suitable for home automation than industrial or retail applications.Īny RPi touchscreen add-on can be combined with a Raspberry Pi and applied to HMI use.
These range from the official, 7-inch Raspberry Pi Touchscreen, which competes with a variety of third-party 7-inchers, as well as 10.1-inch models like the Waveshare Raspberry Pi 10.1 inch. In addition to the all-in-one devices listed here, many more touchscreens are available for the Raspberry Pi 3 that could be turned toward HMI purposes. (It’s unlikely that we’ll see an RPi Compute Module based on the new Raspberry Pi 3 Model B+, which boosts the clock rate to 1.4GHz and offers faster WiFi and Ethernet, as well as Power-over-Ethernet.) The CM3 gives you the same quad-core, Cortex-A53 Broadcom BCM2387 SoC as the Raspberry Pi 3, but without the real-world ports and built-in WiFi and Bluetooth.

The first three models here use the stripped-down Raspberry Pi Compute Module 3 (CM3) while the last three use the full Raspberry Pi 3 Model B SBC. Here we look at six RPi-based contenders.

Touch-panel systems based on Linux, and to a lesser extent, Android, are gaining share from those that use the still widely used Windows Embedded, and over the past year, several Raspberry Pi based systems have reached market.
The industrial touch-panel computer market has been in full swing for over a decade. Yet, in noisier industrial and retail IoT environments, touchscreens are usually the only choice. In the smart home, voice agents are increasingly replacing the smartphone touchscreen interface as the primary human-machine interface (HMI).
