STM32-P405 user's manual
CHAPTER 1 OVERVIEW
1. Introduction to the chapter
Thank you for choosing this general-purpose development board designed and assembled by Olimex!
This document provides a user’s guide for the Olimex STM32-P405 board. As an overview, this chapter
gives the scope of this document and lists the board’s features. A comparison between boards similar to
STM32-P405 is presented. The document’s organization is then detailed.
The STM32-P405 development board enables code development of applications running on the
microcontroller STM32F405RG, manufactured by STMicroelectronics.
STM32-P405 board is a medium-sized development board with a small prototype area. Using STM32-
P405 you can explore the features of STM32F4 family on budged. The board has everything necessary
for a large number of different applications: USB port for communication and powering; separate power
jack for powering; reset and oscillator circuits; JTAG port for programming and debugging; serial driver
and DE9 connector; UEXT expansion connector; prototype area; programmable LED; programmable
button and much more.
There are plenty of GPIOs available at the GPIO area which can be used to connect your additional
circuits.
