Meet the NuMaker-UNO-M4: A Powerful Upgrade to the Classic Arduino UNO
Are you looking for a modern, powerful alternative to the classic Arduino UNO? The NuMaker-UNO-M4 from Nuvoton Technology could be just what you need! It’s a new development board with the familiar Arduino UNO size and shape, but it’s packed with advanced features perfect for hobbyists, students, and professionals alike.
What Makes the NuMaker-UNO-M4 Special?
1. Compatible with Arduino UNO
The NuMaker-UNO-M4 uses the same pin layout as the Arduino UNO. That means if you already have Arduino shields (expansion boards), they will work right out of the box with this new board.
2. Powerful Processor
At its heart is the NuMicro M467SJHAN microcontroller—a 32-bit Arm Cortex-M4 chip running at 200 MHz! With 512kB of SRAM and 1MB of flash memory, it can handle much bigger and more complex projects than the old UNO. It also supports advanced math, digital signal processing, and more.
3. Lots of Extras
Modern Connections: The NuMaker-UNO-M4 supports Ethernet, RS485, and CAN Bus. These are popular for industrial and smart projects.
Data Storage: There’s a header for a microSD card, so you can easily store and access large amounts of data.
Easy Powering: Use a modern USB Type-C cable for data and power, or connect an 8–18V barrel jack for more demanding projects.
4. Designed for the Real World
This board is great for making smart transportation systems, home automation, healthcare devices, industrial robots—pretty much any modern project where you need reliability and speed.
How Does It Compare to the Arduino UNO?
The classic Arduino UNO is a great learning tool and is still used by millions. But its processor is slower and has much less memory. The NuMaker-UNO-M4 can do everything the UNO can—plus much more, thanks to its faster ARM core, extra storage, and industrial-level connectivity.
Getting Started Is Easy
You can use the same Arduino IDE (the software you program Arduinos with), making it easy to move your existing projects over or start something brand new.
Price and Availability
The NuMaker-UNO-M4 costs about $33. That’s a great deal for the performance you get! Check out the Nuvoton website for more info and to see when it’s available near you.
In Short:
If you love the Arduino UNO but want more speed, memory, and features for your projects, the NuMaker-UNO-M4 is a fantastic new choice. It’s ready for hobbyists and professionals who want to build the future.
