STM32 Pinout Configuration.
The STM32 pinout is a Nucleo board from STMicroelectronics. To an extent, it is pretty low in cost and easy-to-use relatively.
(The STM32 blue pill diagram is fully labeled).
For example, the STM32 Nucleo F401RE development board comes with an ARM 32-bit cortex microcontroller. This microcontroller often comes in a single LQFP64 package without a separate probe.
Moreover, there is an inbuilt debug interface/debug port and ST-LINK header/V2-1 programmer for memory access and transmissions. Some examples include the ARM Cortex-M4F core, ARM Cortex-M33 core, ARM Cortex-M3 core, and ARM Cortex-M7F core.
Although similar to Arduino Uno, the STM32 pinout has extra pins for increased performance. As a result, this board is doing very well commercially.
In general, the STM32 pin setup has two types. On one side are the male pins for the STM itself.
On the other hand, are the female pins for Arduino connection. Hence, it is possible to connect different Arduino headers because of its extension pin headers.
As part of its configuration, the STM32 pinout has three LEDs:
- LD 1 or first LED– This serves as an indicator for USB connection and communication.
- The LD 2 or second LED – This indicator is the programmable user LED.
- LD 3 or third LED – The power supply indicator is on this end.
In the same way, there are two PUSH buttons with separate adequate functions. One of which is for programming the microcontroller as a user. The RESET button, on the other hand, has an alternate position.
Often, the programming board uses an input voltage of 3.3V. However, a voltage ranging from 7-12V is still suitable when supplied through the Vin pin because it has an analog voltage regulator.
Nucleo-F401RE Pinout Configuration
To further understand the STM132, let us discuss the Nucleo F401RE pinout configuration.
As mentioned earlier, two sets of pins are in the STM132 Nucleo board pinout diagram.
On the one hand, you have the Arduino shield pins.
On the other hand, there are morpho pins connecting the STM132 module.
The Arduino pins have the CN5, CN6, CN8, and CN9 categories. We have also tabulated each pin category to better describe it.
GPIO Pinout configuration.
Conversely, the developer board has a set of GPIO pins.
In this case, the GPIO pins function as male headers, totaling 76 pins.
Further, we classify the GPIO pins into CN7 and CN10, each with 38 on each side.
These are the GPIO pins, timer pins, ground pins, power pins, and analog pins.
