The STM32 is a family of microcontrollers produced by STMicroelectronics, and they're quickly becoming a favorite among electronics enthusiasts. There are a few key reasons why the STM32 is a great alternative to the Teensy 4.0:

  1. Price: While the Teensy 4.0 is a powerful microcontroller, it comes with a price tag to match. The STM32, on the other hand, is much more affordable while still offering comparable performance.
  2. Versatility: The STM32 comes in a variety of different models, each with its own unique set of features. This means that you can choose the model that best fits your project's needs, whether you need more processing power or more I/O pins.
  3. Compatibility: The STM32 is compatible with the popular Arduino development environment, which makes it easy to get started if you're already familiar with Arduino.
  4. Open-source: The STM32 is an open-source platform, which means that the software and hardware designs are freely available to the public. This makes it easier to troubleshoot and customize your projects.
  5. Community: There's a growing community of STM32 enthusiasts who are creating libraries and sharing their projects online. This means that you can find support and inspiration as you work on your own projects.

We are proud to anounce the first prototypes of the board where manufactured and assembled by JLCPCB, we usually like to share some photos of the assembly process but in this case we didn't had to go thoght the trouble of hand soldering. As the first time using their assembly process we have to say the quality was outstanding, we though our soldering skills where on point the their pick and place machines are just in another level.

 Using JLC PCB is a great option when manufacturing an STM32 board for several reasons:

  1. Affordability: JLC PCB offers very competitive pricing for small batch PCB manufacturing. This is especially useful for hobbyists and small businesses who may not have the budget for large-scale production runs.
  2. Quality: JLC PCB has a reputation for producing high-quality PCBs with excellent tolerances and consistent performance. This ensures that your STM32 board will function reliably and accurately.
  3. Speed: JLC PCB has a fast turnaround time for PCB manufacturing, which means that you can receive your STM32 board quickly and get to work on your project right away.
  4. Flexibility: JLC PCB offers a wide range of options for customization, including PCB thickness, surface finish, and solder mask color. This allows you to tailor your STM32 board to your specific needs.
  5. Support: JLC PCB provides excellent customer support and online resources, including a forum for customers to ask questions and share their experiences. This can be especially helpful for hobbyists and beginners who may have questions or need guidance.

 In summary, using JLC PCB for manufacturing an STM32 board can provide an affordable, high-quality, and flexible solution with fast turnaround times and excellent customer support. This can make JLC PCB a great option for hobbyists and small businesses who want to bring their electronics projects to life.

The development board is pin-compatible with the original Teensy 4.0, this way we can reuse all the projects where the teensy was used but with an improved and cheaper microcontroller. The main purpose of this board was to end with th supply dependence we had on the Teensy boards which has been kind of short lately.
