STM32F405 Development Board

The STM32F405 development board is a small but powerful development board that we typically recommend for real-time control systems & DSP projects. The target microcontroller on this board has an ARM Cortex-M4 processor that can run @ up to 168MHz. This board has a handful of onboard HW peripherals to ease your job of prototyping your projects.

The shown below is my STM32F405 development board that I got from WeAct official store.

STM32F405 Board Pinout Diagram (WeAct)

The STM32F405 development board (by WeAct) doesn’t have a pinout diagram because it’s got silkscreen labels on the back side of the PCB itself as shown in the image below.

You can also refer to the schematic diagram PDF document to make sure how the GPIO pins are connected to the target microcontroller and which pins are used for the physical onboard features (i.e. Buttons, User LED, SD Card, etc).

This is the schematic diagram of the STM32F405 development board (by WeAct). This is a multi-document schematic design that can be found on the following Github repo by WeAct. (Full Schematic Design File)


Wrap Up

The STM32F405 development board is a very solid mid-range STM32 development board that you can get for projects that require a lot of DSP operations and decent CPU performance. I’ve been using this board for real-time control projects as well as various DSP applications for rapid prototyping before designing a custom PCB for each project based on the STM32F405 target microcontroller.

You can check the WeAct GitHub Repo for this development board for more documentation details & example projects. The official WeAct store is linked below in case you’d like to buy this development board.
