Makerfabs' $80 ESP32-P4 Touch Panel Adds 4G, Ethernet, and a Camera
Makerfabs' MaTouch ESP32-P4 is an $80 10.1-inch HMI dev board with 4G LTE, Ethernet, a 2MP camera, and RISC-V power — an all-in-one maker panel shown June 26, 2026.
An All-in-One Touchscreen Brain for Makers
Sometimes the most exciting hardware isn't the most powerful — it's the most *complete*. The Makerfabs MaTouch ESP32-P4, which surfaced on June 26, 2026, is a lovely example: a 10.1-inch touchscreen HMI development board that bundles cellular, wired networking, and a camera into one ready-to-build package for $79.80. For makers building smart-home dashboards, kiosks, or connected control panels, that's a remarkable amount of integration at a friendly price.
The ESP32-P4 at the Core
The board is built around Espressif's ESP32-P4, a dual-core RISC-V processor running its high-performance cores at up to 400 MHz alongside a low-power 40 MHz core for efficiency. Because the P4 doesn't include its own radio, Makerfabs pairs it with an ESP32-C6 companion chip to handle wireless. That combination gives you Wi-Fi 6, Bluetooth 5 LE, and 802.15.4 for Thread and Zigbee — a strong foundation for anything in the smart-home and IoT world.
Connectivity That Goes Well Beyond Wi-Fi
This is where the MaTouch panel really distinguishes itself. On top of wireless, it includes 10/100 Ethernet for a rock-solid wired link, and — unusually for a board at this price — a SIMCom SIM7670G 4G LTE Cat 1 modem with a nano-SIM slot. Cellular connectivity on an $80 HMI panel means you can deploy a dashboard or monitoring device somewhere with no Wi-Fi at all, which opens up a lot of real-world projects.
There's also a 2MP MIPI camera capable of up to 1080p capture, six USB-C connectors for various roles, a microSD slot, and two 40-pin GPIO headers for expansion. Helpfully, it ships in an enclosure with a 32 GB microSD card included, so you can start building right away.
The Display and the Build
The screen itself is a 10.1-inch IPS LCD at 1280 × 800 with 10-point capacitive multi-touch — a generous, responsive canvas for building graphical interfaces. Combined with the GPIO headers and the camera, it's a tidy platform for everything from a whole-home control panel to a small interactive kiosk or a connected workshop monitor.
The Takeaway
What I appreciate about the MaTouch ESP32-P4 is how much friction it removes. Rolling your own carrier board with a display, cellular modem, Ethernet, and a camera is a real project on its own; here it's all on one RISC-V dev board for under $80, enclosure and storage included. For makers who'd rather spend their time on the *idea* than the plumbing, that's exactly the kind of accessible, all-in-one hardware that keeps the maker scene thriving.
