00:00Alright, let's talk about the unsung heroes of custom electronics builds, the screens
00:04that actually let you control your project without typing code into a serial monitor
00:08like it's 1998.
00:10If you're building an embedded control system, whether it's a home automation panel, a 3D
00:15printer interface, or some crazy custom CNC rig, you need a reliable HMI touch display.
00:21I spent way too long digging through spec sheets and user reviews, but I finally found
00:25the best deals for the top 5 HMI touch displays for embedded control.
00:30These are the ones people are actually buying, loving, and using to bring their projects
00:34to life, and I'm breaking them down for you right now.
00:37First up, we have the Nexion Enhanced NX4024K032.
00:42This is a 3.2-inch display that is an absolute workhorse for the price.
00:47The standout feature here is the upgraded faster MCU clock combined with a built-in RTC, or
00:53real-time clock, and 1K of EEPROM for user data.
00:56That means you can run complex animations and log data without needing a separate clock
01:01module or external memory chip cluttering up your build.
01:04It also gives you 8 digital GPIO pins to play with, so it's not just a screen, it's an I
01:09.O.
01:09expander.
01:11At $34.99, with nearly 5,000 units sold and a perfect 5-star rating, it's a no-brainer if
01:18you need a reliable, self-contained interface that handles the logic so your main microcontroller
01:22doesn't have to. If you're working with tighter space or a tighter budget, the Nexion NX3024K028
01:29is the smaller sibling that still packs a punch. This is a 2.8-inch resistive touch display from
01:35the Enhanced series, and it's practically legendary for its compatibility with Arduino.
01:40The best feature here is that it uses UART serial communication, which means you only need
01:46two wires to get it talking to your board. It's super easy to program with the Nexion
01:50editor, making it perfect for beginners who want a professional-looking GUI without a massive
01:55learning curve. At just $27.99, and with almost as many sales as the first one, it's the go-to
02:03choice for retrofitting older Arduino projects with a modern touch interface. Now, if you want
02:08the absolute best bang for your buck in terms of raw power and connectivity, check out number
02:13three, the JC2432W328C ESP32. This thing is a beast. It's a 2.8-inch capacitive touchscreen,
02:23which feels way more premium than resistive, and it runs on the ESP32 chip with built-in Wi-Fi
02:28and Bluetooth. That means you can control your embedded system from your phone or integrate
02:33it into a smart home network right out of the box. The SC7789 driver ensures a crisp,
02:39fast refresh rate for your graphics. The wild part? It's only $7.35. I'm not kidding.
02:49With over 4,800 sold at a 5-star rating, this is the ultimate budget board for IoT projects where
02:55you need a screen and wireless connectivity without breaking the bank. Next, we're stepping
03:00up to a larger canvas with the DWIN 4.3-inch HMI display. This one is for those who need
03:07a bit
03:07more real estate and a higher resolution. It features a 480x800 IPS panel, which means great
03:14viewing angles and vibrant colors, available in either capacitive or resistive touch options.
03:19What makes this DWIN module special is its TTL-UART interface and the fact that it's designed
03:25specifically to work seamlessly with Arduino and other microcontrollers. It's a professional-grade
03:31module typically found in industrial equipment, but it's available here for just $14.55.
03:37With a perfect rating and nearly 4,800 sales, it's proof that you don't have to spend a fortune to
03:43get a high-resolution, responsive interface for your control panel. And finally, for the ultimate
03:49plug-and-play experience, we have the Nexion NX4827P043-011 or Y. This is a 4.3-inch intelligence
03:58series display, and the best part is that it comes with an enclosure. If you've ever tried
04:03to 3D print or laser-cut a bezel for a screen, you know what a headache it can be to
04:07get the
04:07tolerances right. This unit solves that by giving you a finished, professional-looking panel that
04:13looks like it belongs on a commercial product. It's a resistive touchscreen, which is great for
04:18industrial environments where you might be wearing gloves, and it has plenty of onboard memory for
04:23complex UI designs. At $54.90, it's the premium option on this list, but considering it's ready
04:30to mount and has a flawless 5-star rating from over 4,700 buyers, it's worth every penny for a
04:36clean,
04:36finished build. So, there you have it, 5 killer options for your next embedded control project.
04:43Whether you're spending $7 or $50, there's something here that will make your build look
04:47and feel professional. I've put links to all of these displays in the description below so you
04:52can check the current prices and specs for yourself. If you found this helpful, give the video a thumbs
