You can use any Nucleo board to complete this tutorial. Similarly, keep an eye on the CircuitPython list of supported Nucleo boards. Some of them even have Arduino and PlatformIO support. Most of them have support in ARM’s mbed online editor/compiler. This chart on ST’s site offers a useful visual for choosing the right Nucleo board.Īll of the Nucleo boards can be programmed using assembly, C, or C++ with the GNU ARM Toolchain (in any number of IDEs). Note that not every STM32 part has an associated Nucleo board. Note the double row Arduino-compatible headers, which allow the Nucleo-144 to accept Arduino shields. These boards often include the most powerful and largest of the STM32 microcontrollers.

Nucelo-144: More pins than you can shake a stick at.

Nucleo-64: Arduino-like boards with the Arduino pinout.

Nucleo-32: Breadboard-compatible development boards useful for learning and small projects.

The 3 pinout versions are referenced by the number of pins: Once again, the naming convention of the Nucleo line can be slightly daunting.

All include built-in ST-LINK/V2 circuitry for in-circuit debugging, which rely on the Serial Wire Debug (SWD) implementation of the JTAG interface. The Nucleo boards have a similar set of features with 3 standard pinouts.

The Nucleo series of boards are their most popular. In addition to just manufacturing chips, ST has given us a number of development boards to aid in our learning process. ST’s HAL libraries also make this transition seamless, as it abstracts away most direct register reading and writing. If you are working with an STM32F0 and find that you are running out of resources in the controller, you can (in most cases) drop a F1 series with the same package in its place on your board, and it will just work. Microcontrollers that come in the same package are often pin-for-pin compatible.

ST has worked to make transitioning among its lineup as seamless as possible. USB Type-C is also available on many of the G4 series. Similar to the F3 with even more power: up to 170 MHz.

STM32G4 Series: Based on ARM Cortex-M4.

STM32G0 Series: Based on ARM Cortex-M0+, which works similarly to M0, but has some extra features to allow for low-power operation.

The M4 architecture is very similar to the M3 architecture with added digital signal processing (DSP) functions, such as a hardware floating-point unit (FPU) and specialized assembly instructions (e.g.

STM32F3 Series: Based on ARM Cortex-M4.

These microcontrollers generally have more speed, memory, and peripherals than their Cortex-M0 cousins.

STM32F1 Series: Based on ARM Cortex-M3.

Inexpensive and a good place to start if you’re coming from the 8- and 16-bit microcontroller world.

STM32F0 Series: Based on the ARM Cortex-M0 architecture.

At the time of this writing, you can choose among: Within the Mainstream line, you have a number of options. If you are just starting out, I recommend sticking with the Mainstream line to learn the ropes. This should help you figure out which microcontroller you should use depending on your application(s). For now, we will focus on the 32-bit MCUs.Īdditionally, you can see that the 32-bit MCUs (non-automotive) are divided up into 4 categories: Mainstream, Ultra-low-power, High-performance, and Wireless. Image credits: STMicroelectronics Microcontrollers and MicroprocessorsĪs you can see, ST has 8-bit microcontroller units (MCUs), 32-bit microprocessor units (MPUs), 32-bit MCUs, and 32-bit MCUs designed for automotive use. There, you still find an overview of their offerings, likely in a chart like the one below.

The most useful place to start is on their Microcontrollers and Microprocessors page. STMicroelectronics offers a dizzying array of microcontrollers and microprocessors.
