00:00If you've ever wired up a control panel and thought, there has to be a better way than a bunch
00:04of buttons and a tiny character LCD, yeah, same.
00:08UART HMI touchscreens basically let you drop a full graphical interface onto any project with just a couple of serial
00:14wires.
00:15I've been digging through listings for weeks, and I pulled together the 5 best UART HMI touchscreens for industrial panels,
00:22plus the deals that actually make them worth grabbing right now.
00:26Let's get into it.
00:28Starting off with the HMI Intelligent Smart Use Art UART Serial Touchscreen TFT LCD Module for Arduino.
00:35What I like most here is how genuinely beginner-friendly it is, you design your screens in the editor on
00:40your PC, upload them to the module, and then your Arduino just sends simple serial commands.
00:45All the heavy graphics work happens on the display itself, so your microcontroller barely breaks a sweat.
00:52It's the priciest one on this list at $226, but over 4,700 people have bought it and it's sitting
00:58at a 4.7 rating.
01:00If you're building something you need to be rock-solid and well-documented, this is the safe bet.
01:06Next up is the 5-inch NX8048T050 Intelligent TFT Touch Display, which works beautifully with a Raspberry Pi.
01:145 inches is honestly the sweet spot for a lot of panel builds, big enough for reel gauges, graphs, and
01:19menu screens, but still small enough to fit a standard enclosure without redesigning your whole front plate.
01:26It's $195, a bit cheaper than the first one, and it's got the best rating of the two big-name
01:31options at 4.8 with over 4,500 sold.
01:34If you're running a Pi-based monitoring station, this one just slots right in.
01:39Now here's the one that made me do a double take.
01:43The DWIN 7-inch, 800x480HMI Intelligent TNT FT Display with Commercial Grade Capacitive Touch, $22.58
01:53That is not a typo.
01:55You're getting a 7-inch capacitive touch panel with a UART interface for less than the price of lunch for
02:00two, and it's got a perfect 5-star rating across 4,400-plus orders.
02:06Capacitive touch means smooth, responsive swipes instead of that mushy resistive feel.
02:11If you're prototyping, or you need several panels for a build, this is the best value on the entire list,
02:16full stop.
02:18Stepping up a little, we've got the 2026 DWIN 7-inch with the enclosure, same 800x480 resolution, but this one
02:26ships with a proper housing and adds RS-232, RS-485, and Modbus support.
02:31That Modbus bit is the real story here, because it means you can drop this straight onto an existing industrial
02:37bus and talk to PLCs, sensors, and drives without writing a translation layer.
02:42$55 for a fully enclosed, industry-ready panel is genuinely reasonable.
02:474.8 rating, over 3,700 sold.
02:51If this is going into an actual machine and not just a bench project, this is the one I'd pick.
02:57And rounding it out, the 2026 DWIN 7-inch high-brightness industrial panel at 1024x600.
03:05Two things set this apart, the higher resolution gives you noticeably crisper text and room for more data on screen
03:10at once,
03:11and the high-brightness panel means you can actually read it in a bright workshop or near a window.
03:16That's a real problem with cheaper screens that just wash out.
03:20It's $94.93 with capacitive touch and RS-232 built-in.
03:25The 4.5 rating is the lowest here, so it's not flawless, but for demanding environments the brightness alone earns
03:32its spot.
