| The CrowPanel Advance is a new smart home display with ESP32 |
If you’ve been keeping an eye on the DIY smart home scene, you know that the ESP32 has become something of a legend. Low cost, solid performance, and that sweet, sweet wireless flexibility. But what if you could take that beloved chip, wrap it in a compact touchscreen display, and add AI smarts, voice control, and even off-grid mesh networking? That’s exactly what Elecrow’s new CrowPanel Advance 3.5”-HMI brings to the table — and it’s turning heads in the maker community for all the right reasons.
Priced at an eye-watering $25 (direct from the manufacturer), this little panel packs a surprising punch. Let’s tear into what makes it special, who it’s for, and why you might want one (or three) for your next home automation project.
Under the Hood: The ESP32-S3 You Know and Love
At its heart, the CrowPanel Advance runs on the ESP32-S3-WROOM-1-N16R8 module. That’s a dual-core LX7 processor clocked up to 240MHz, with 16MB of flash and 8MB of PSRAM. For anyone who’s built a smart display or IoT dashboard before, those specs will sound familiar — and capable.
Out of the box, you get:
- 2.4GHz Wi-Fi and Bluetooth 5 LE (with long-range support)
- A 3.5-inch IPS touchscreen at 480×320 resolution
- Built-in microphone and speaker
- Support for speech recognition and text-to-speech (the “AI” part of the name)
But here’s where it gets interesting. The board has headers and expansion options for additional wireless modules. Want LoRa for Meshtastic? No problem. Need ZigBee, Matter, Thread, or even Wi-Fi 6? Slap on the corresponding module and you’re good to go.
That means this tiny display can become a universal smart home hub — not just a pretty face.
Meshtastic Support? Yes, Please
One of the more unexpected features is official Meshtastic support. For the uninitiated, Meshtastic is an open-source, off-grid mesh communication platform that runs on LoRa radios. Think walkie-talkies meets text messaging, without cell towers or the internet. It’s huge among preppers, campers, and anyone who wants decentralized communication.
With the right LoRa module attached, the CrowPanel Advance can act as a Meshtastic node with a full graphical interface. You could mount it on your wall to display mesh messages, node locations, or signal strength — all while sipping power from a connected battery. That’s a niche but genuinely cool use case you don’t see every day.
Building Your Own Interface: LVGL, Arduino, PlatformIO
Elecrow isn’t handing you a finished product with pre-loaded smart home software. This is a developer-first board. You’re expected to program your own user interface, which might sound daunting until you realize the ecosystem support.
The display comes with LVGL (Light and Versatile Graphics Library) support baked in. LVGL is the go-to for embedded GUIs — it’s lightweight, widget-rich, and surprisingly fun to work with. You can drag-and-drop UI elements in SquareLine Studio or code directly.
Programming options include:
- Arduino IDE (classic, tons of libraries)
- PlatformIO (better for larger projects)
- ESP-IDF if you want to go bare metal
There’s also example code and documentation for getting the touchscreen, audio, and wireless features up and running quickly. So while it’s not a “plug and play” Home Assistant dashboard out of the box, a motivated maker could turn it into one over a weekend.
What About Smart Assistants?
The built-in microphone and speaker aren’t just for show. Because the ESP32-S3 has enough juice to run lightweight speech recognition models, you can integrate the panel with voice assistants — local ones like Rhasspy or cloud-based via Wi-Fi. Imagine tapping the screen or saying “Hey panel, turn off the lights,” and having it actually work. Text-to-speech means it can talk back, too.
No, this isn’t an Amazon Echo. But for a custom smart mirror, bedside controller, or kitchen recipe display with voice commands? Absolutely doable.
Connectivity Galore
One of the strongest selling points is how many external things you can hook up. The board exposes GPIO pins for sensors, actuators, relays, and more. There’s also a battery connector — so you can run this thing wirelessly for hours. Perfect for a portable Meshtastic terminal or a wall-mounted panel that doesn’t need a visible power cord.
Here’s the full list of what you can add via modules:
- LoRa (for Meshtastic, TTN, etc.)
- ZigBee
- Matter / Thread
- Wi-Fi 6
- Pretty much anything with a UART or SPI interface

Pricing: $25 Sounds Great, But Read the Fine Print
At $25, the CrowPanel Advance is aggressively priced. For comparison, a bare ESP32-S3 dev board plus a separate 3.5” touch display would easily cost $35–40. Here you’re getting an integrated PCB, audio, and a slick IPS panel.
However, that $25 does not include:
- A protective case (you’ll need to 3D print or buy one)
- Any additional wireless module (LoRa, ZigBee, etc.)
- A battery
- Shipping
So factor in another $10–20 depending on your add-ons. Still, it’s a bargain for what you get.

Who Is This For?
Let’s be real — this isn’t your average consumer smart home gadget. Grandma won’t be mounting one next to her Nest thermostat. But if you’re a:
- DIY smart home enthusiast looking to build a custom control panel for Home Assistant or OpenHAB
- Meshtastic user wanting a dedicated graphical node
- Student or prototyper who needs a fast, cheap HMI for a project
- Tinkerer who just loves ESP32 and LVGL
…then the CrowPanel Advance is an absolute steal.
Alternatives to Consider
If you’re not ready to write your own firmware, pre-built options like the Sonoff NSPanel (with Tasmota) or Home Assistant’s own voice hardware might be more your speed. But they’re less flexible, often more expensive, and don’t support Meshtastic or LoRa.
For pure ESP32 touch displays, the M5Stack Core line is a competitor, but you’ll pay 2–3x more for similar specs. The CrowPanel Advance undercuts almost everything at this feature set.
Final Verdict: A No-Brainer for Makers
The CrowPanel Advance 3.5”-HMI isn’t trying to be a polished consumer product. It’s a blank canvas for makers, and a damn good one at that. ESP32-S3, IPS touch, audio, and expansion for LoRa/ZigBee/Matter — all for $25. Support for Meshtastic is the cherry on top.
If you’ve been dreaming of building your own smart home dashboard, a portable off-grid communicator, or an AI voice-controlled interface, this is your sign to grab one. Just remember to budget for a case and the wireless modules you actually need.
Pros:
- Incredible value for money
- Powerful ESP32-S3 with PSRAM
- Built-in mic and speaker
- LVGL + Arduino + PlatformIO support
- Meshtastic compatible
Cons:
- No case included
- Additional wireless modules sold separately
- Requires programming (not for non-technical users)
