README

A custom development board based on the STM32H573RIT6 microcontroller, created in KiCad that serves the purpose of learning about the hardware design, PCB layout, power supply and embedded systems.
Features
Core components
- Power supply: The board is powered through the USB-C connector. 3.3 V is supplied by the LD1117S33TR regulator.
- Microcontroller: The STM32H573RIT6 processes the firmware code and communicates with peripherals.
- Clock source: 8 MHz crystal serves as an external clock for the microcontroller.
- Pushbuttons and resistors: Used to reset and enter the boot mode.
- USB Protection: USBLC6-2P6 is used for ESD protection of the USB lines.
- Programming and debugging: SWD connector is used for flashing firmware and debugging.
- Headers: Expose some of the pins for expansion.
The reason behind making this
This board was made by me in order to gain knowledge about how to make an STM32 development board on my own rather than relying on readymade boards available out there.
Flashing and use
The board is equipped with a USB-C port thus it can be connected to a PC. In case that USB DFU bootloading is set up properly, you may flash the firmware directly via USB and no ST-LINK debugger will be required.
Otherwise, it is still possible to program and debug the board via ST-LINK through the SWD connector.
After flashing the firmware, reboot the board and get started playing around with GPIOs!
Assembly
The PCB assembly will be done by manually soldering all the parts to the PCB.

Questions
How big is the Stm devboard PCB?
It measures 65 × 75 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Stm devboard use?
70 parts, built around the USBLC6-2P6 and DMG1012T. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Stm devboard KiCad files?
From the AYUSH-pro-grammer/stm-devboard repository on GitHub, at the commit this page was made from: the board is stm-devboard/stm-devboard.kicad_pcb and its schematic stm-devboard/stm-devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask AYUSH-pro-grammer before reusing the design.
