From the project
Development board based on the STM32F411RET6
This is an educational development board conceived as part of a PCB Design course. The course is offered via Portal Embarcados website (Course Page).
The board is based on the STM32F411, more specifically, the STM32F411RET6. Additionally, the board features some components commonly used in Embedded Systems, such as: - DC-DC Converters - OLED Display, connected to the MCU via I²C - RGB LEDs - Audio buzzer, controlled via PWM - External ADC with analog antialiasing filters - USB 1.1 Full Speed via a Type-C connector - Micro SD Card for easy data storage, connected to the MCU via SPI - Input…

STM32XP: common questions
What microcontroller does the STM32XP use?
The STM32XP is built around the 61300411821, from the STM32 family.
How big is the STM32XP PCB?
The STM32XP measures 99.1 × 68.6 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the STM32XP?
166 components, from 67 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the STM32XP design files?
From the MechatronixLab/STM32XP repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the STM32XP design in my own project?
Yes, under the terms of its CERN-OHL-P-2.0 license, which MechatronixLab chose for the repository.
Can I test firmware for the STM32XP without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
