Introduction

In this article, we will be discussing the STM32 board and its programming challenges. We will explore a neater solution for programming the STM32, including the use of the Black Pill board. We will also compare different USB to serial converters and discuss the advantages of using PCB Way for ordering PCBs. Additionally, we will take a closer look at the design and features of the STM32 board. So, let's dive in and explore the world of STM32 programming and development.

The Problem with Programming the STM32

If You have ever programmed an STM32 board, you may have encountered various challenges. One common issue is the difficulty of getting the USB port to work. Many users have reported encountering the "USB device not recognized" error, even after installing drivers and trying various troubleshooting steps. This can be frustrating, especially when you can't figure out why the USB communication is failing.

Moving to a Neater Solution

To overcome the challenges of programming the STM32 board, many users have opted for a neater solution. One popular option is using an FTDI interface, which acts as a bridge between USB and serial communication. This allows for easier and more reliable programming of the STM32 board. By using an FTDI interface, users no longer need to deal with messy wiring and can achieve a more streamlined programming process.

Introducing the Black Pill

While the FTDI interface is a great solution, some users have explored alternative boards that offer improved usability and compatibility. One such board is the Black Pill, a newer version of the STM32 Blue Pill. The Black Pill board offers corrected USB circuitry, which addresses the issues encountered with the Blue Pill. However, it is important to note that the Black Pill is not a straight swap for the Blue Pill. The boards have different sizes, Pin layouts, and compatibility, so it's essential to select the appropriate board for your needs.

Pros

• Corrected USB circuitry
• Potential for better compatibility

Cons

• Not a direct replacement for the Blue Pill
• Different size and pin layout

The USB Compatibility Issue

Despite the claims of corrected USB circuitry on the Black Pill, many users have still faced compatibility issues. It appears that the USB compatibility issue is not entirely resolved, even with the newer version of the board. This highlights the need for further investigation and clarification regarding the improvements made in the Black Pill.

Comparing USB to Serial Converters

When it comes to selecting a USB to serial converter for STM32 programming, there are several options available. One popular choice is the FTDI FT232RL chip, which offers reliable performance and can be conveniently mounted on holes. However, there are also other options such as the CP2102 and CH340G devices, which serve a similar purpose. It is important to consider the compatibility, ease of use, and availability of these converters when making a decision.

Pros

• Wide availability
• Reliable performance
• Convenient mounting options

Cons

• Potential compatibility issues with certain boards
• Limited choices in terms of manufacturers

PCB Way - An Easy Solution for Ordering PCBs

When it comes to designing and manufacturing PCBs, PCB Way offers a user-friendly and efficient solution. Their Website allows users to enter the Dimensions of the PCB, choose the quantity, and select various customization options. PCB Way provides a wide range of PCBs, and their boards are known for their high-quality and reliability. New users even receive a $5 discount on their first order, making it an attractive option for those looking to try out PCB fabrication.

Pros

• Easy PCB ordering process
• Customization options available
• High-quality and reliable boards
• New user discount available

Cons

• Shipping costs may vary depending on location

The Design and Features of the STM32 Board

For those interested in designing their own STM32 board, KiCAD is a powerful tool that offers a comprehensive PCB design experience. With KiCAD, users can Create schematics, layout PCBs, and generate manufacturing files. The 3D viewer in KiCAD allows users to Visualize their design in real-time, ensuring that everything aligns properly. Additionally, KiCAD provides a smooth workflow and allows for easy collaboration on projects.

Using KiCAD for PCB Design

When designing a PCB using KiCAD, it is important to pay Attention to the details and ensure proper net naming and component placement. Creating a schematic before starting the PCB layout can help avoid issues such as overlapping footprints and incorrect connectivity. By following best practices and taking the time to plan and document the design, users can create professional and functional PCBs.

The Future of the Black Pill and STM32 Boards

As the popularity of STM32 boards continues to grow, it is expected that new iterations and improvements will be introduced. It remains to be seen whether the Black Pill will gain widespread adoption and effectively address the USB compatibility issue. Additionally, advancements in USB to serial converters and PCB fabrication processes may further enhance the usability and functionality of STM32 boards. As the community explores and discovers new opportunities, the future of STM32 development looks promising.
