The 6 Best Microcontroller Boards for All Levels
Whatsapp Pinterest

Microcontrollers mostly follow similar designs. They have limited onboard memory, run on low power, and feature a set of General Purpose Input and Output (GPIO) pins, programmable usually via USB cable.

There are so many boards to choose from that it can be hard to pick out the perfect one for you. Beginners have a much different experience working with hardware than people who may have coded, or tinkered with electronics before.

No matter what level you are at, one of these microcontrollers should work well for you.

1. Best Microcontroller for Beginners
Arduino Uno R3

Arduino Uno R3 Arduino Uno R3 Buy Now On Amazon $18.05

If you have interest in microcontrollers you’ve almost certainly heard of Arduino. They popularised open-source hobby hardware with their array of development boards and an Independent Development Environment (IDE) for coding them.

The Arduino Uno R3 is the standard Arduino found in most starter kits and is the easiest to use. If budget is an issue, note that Arduino is open-source hardware. Therefore, copies of the design are entirely legal. If you search for Arduino clones, you will find many at a much lower price than official Arduino boards.

2. Best Microcontroller for Kids

Makeblock mBot Robot Kit Makeblock mBot Robot Kit Buy Now On Amazon $69.99

Hang on, this doesn’t look like a microcontroller board!

Well, the mBot Robot Kit has a microcontroller as its brain. Its design makes it perfect for teaching children about robotics without having to deal with complex code. Visual block code, put together in the Blocky app, transmits to the board via Bluetooth to affect the robot’s behavior.

You can buy the microcontroller separately from the robot kit, but why would you? Robots are the best!

This kit covers everything from building robots to core programming fundamentals. For introducing microcontrollers to a young audience, there is nothing better!

3. Best Microcontroller for Programmers
STM32 F3 Discovery

STMicroelectronics STM32 F3 Discovery STMicroelectronics STM32 F3 Discovery Buy Now On Amazon $19.03

The STM32 F3 Discovery board is an ARM Cortex-M4-based microcontroller for experimenting with every aspect of hardware programming. The board features built-in motion detection, a three-axis gyroscope, a linear acceleration sensor, and a magnetic field sensor.

There are also eight LEDs in a circular arrangement. Note that this board requires a separate FTDI adaptor for communicating with computers via USB. If you’re unsure what that is, one was used in our build your own Arduino guide to communicate with the ATMega328P chip.

Learning how to program the F3 Discovery is a more in-depth process than many other microcontrollers. Luckily, there are libraries to make the process more accessible, and many tutorials start at with the basics. Alongside using the C++ programming language, the board is the subject of The Discovery Book; a getting started guide for embedding the Rust programming language.

4. Best Microcontroller for Wearables
Adafruit Gemma M0

With microcontrollers combining advanced control over LEDs and other components with small form factors and low power requirements, it’s no surprise they show up in costume design and cosplay. The Gemma M0 board from Adafruit is a coin-sized microcontroller perfect for attaching to LEDs or other components using conductive thread. Alternatively, you can use the built-in RGB DotStar LED.

The ATSAMD21E18 chip (try saying that in a hurry) is a step up from the regular onboard controllers for microcontrollers of this type. While you can use standard Arduino type C++, the board comes preloaded with CircuitPython for Python programming and a native USB connection that other boards of this type usually lack.

5. Best Microcontroller for Power
Teensy 3.2

Teensy 3.2 Teensy 3.2 Buy Now On Amazon $26.22

For raw power in a tiny form factor, the Teensy 3.2 line is widely regarded as the best around. The 32-bit ARM Cortex microprocessor runs rings around almost every other board. Alongside the speed, the Teensy has I2C audio integration and several high-quality analog-to-digital converters (ADCs).

Every pin on a Teensy is configurable as an interrupt, and the boards run with 64KB of RAM along with 256KB flash memory. All of this is Arduino IDE compatible using the Teensyduino library, and if the 28 pins of the Teensy 3.2 are not enough for you, a 48 pin Teensy 3.5 and 3.6 are available from the PJRC website.

6. Best Microcontroller for Intermediate Users
Mbed LPC1768 Development Board

Taking the next step on from hobby microcontrollers feels more like a leap. Industrial use embedded hardware can be much more complex, and have a much higher cost of entry on both an equipment and software level.

A good example of a board right on the border between consumer and industry is the Mbed LPC1768 Development Board. This board is a jump up in quality and tools, and the price reflects it. Mbed provides an online IDE for the hardware, and libraries for performing tasks with the GPIO pins and onboard LEDs.

This significant jump in price also reflects a difference in use cases too. Boards like the LPC1768 find use in industry standard situations, and using the board to further your knowledge could be an essential part of learning embedded programming.

Small Boards, Big Plans

This list should help you make an informed decision about which microcontroller is right for you. It is, however, by no means exhaustive, and misses out great boards like the Arduino killing NodeMCU.

Whichever board you settle on, microcontrollers are the perfect way to combine electronics and coding.

    These boards look like interesting boards... 5 years ago.

    LPC1768 is totally obsolete and is only expensive because of this. The new LPCXpresso (around LPC54 for example) will be much cheaper, more powerful, still compatible with Mbed and MCUXPresso, a non limited IDE based around Eclipse.

    Also, ST has released Nucleo Boards available in 32, 64 and 144 pins that are really cheap and use the full range of STM32 MCUs for a few bucks.

    Also for around 60 to 80$, you can get a Cortex-M4 or Cortex-M7, also compatible with Mbed, with a nice display, Ethernet and digital audio
