STM32F401 V1.2 End Of Life , STM32F411 V1.3 End Of Life Since 2019.11.If the online shopping platform is still sold, it is fake!!

2020.06 , STM32F401CC V3.0 End Of Life , Replace With STM32F401CE V3.0 (84Mhz, 512KB ROM, 96KB RAM).If the online shopping platform still sells STM32F401CCU6, it is fake!!

"Description of Logo and version number"

We do not produce the boards that we received without the Logo WeAct && version number. If we find that the sellers are selling fake goods, we hope you can send us the issues or send us an email(, and we will list the sellers on it, so that more people will not be deceived!!

Our Boards

  • 411 adopts lead-free gold-sinking process, 401 adopts lead-free process, and the needles are gold-plated. All materials conform to ROHS standard, and lead is harmful to health, while piracy USES lead for profit

  • All use the latest batch of chips to give customers the best product experience

  • 25MHZ high speed crystal vibration & 32.768khz low speed crystal vibration adopt high quality metal shell crystal vibration, the starting effect is better

  • Flash disk is reserved to meet the needs of big data storage and microPython. USBDisk&&FATFFS routine is provided

  • Support for MicroPython programming with available MicroPython firmware

  • Support for Arduino programming, see detailsGithub

  • Version V3.0, there are three keys, reset key, BOOT0 key, user key

"Chip batch introduction"

We are committed to always use the best raw material, using the latest chips, users get the best user experience, improve the efficiency of development, from the picture we can know is the 014 batches of chips, The 14th week of 2020,is in the middle of march to make chips, batch is very new, user experience is very good!!!!! But piracy often USES is very ancient vintage chips, such as the recent discovery of piracy is 537 batches of chips, 15 years of production, all over the past five years, the use of very ancient vintage chips of the most likely problem is through the USB download problem, customer difficult or unable to use the USB to download the program directly, but this is not the only problems, the user can appear in the process of using all kinds of puzzling problem, directly increase the cost of development, is very deadly!!!!!!

Our Board Packaging

"Chip batch introduction"

It can be seen from the picture that both the needle arrangement and the board are packaged independently, and the biggest function is to avoid the collision between the inserting needle and the board due to the long-distance transportation of express, which will affect the aesthetics of the board or even the function of the board. Moreover, the bag we use is a self-sealing bag for recycling and environmental protection.But packaging time will be longer and labor costs higher.But the pirated copies sold by the profit merchants are hot-sealed packaging, which means the bags need to be opened with scissors for one-time use,If the customer received the board with pins in the same bag, then the board is definitely a piracy, please report the business and comment that this is a piracy, so that more people will not be deceived!!

STM32F401CCU6 We have stopped production in 2020.6, if the online shopping platform merchant's promotional materials are still marked STM32F401CCU6, then this merchant sells piracy, please do not buy!! New product STM32F401CEU6 in the old product STM32F401CCU6 program is also applicable, but more memory, better performance, shipping price unchanged, and microPython perfect support, no need to change any files, can be said to be the cheapest Pyboard!!

Thank you for Richard·Balint !!

With the pin allocation diagram, it's easier to work with MicroPython and Arduino!

Important Note

  • Recently, online shopping platforms have seen a large number of counterfeits, that is, pirated copies. We found that these counterfeits do not have WeAct && version Numbers on the back.And the boards are not lead-free, and we all know that lead is bad for you.The chips are not the latest batch, or even refurbished.Not only production materials, and production quality closes nevertheless, factory inspection to elaborate (we have a special factory program to test whether each hardware qualified), so that customers in the process of using pirated will appear all sorts of puzzling problem, increase the learning cost, harm the interests of themselves, but also severely damage our WeAct Studio product image.

  • original is not easy, everyone knows our WeAct Studio is the main idea of a Studio is committed to design unique electronic module, we create STM32F401, STM32F411 both core board, and we to micropython CMSIS-DAP for support, and to the open source community Arduino did support, fill the market blank, can make the product easy to develop, and we produce raw materials for the core plate is the best.However, this good product has been violated by the interest of the business, piracy, copy, inferior products, make us in hot water, to a certain extent dampened our enthusiasm.But we are still in the spirit of providing a good platform for the majority of electronic fans, we continue to maintain our project, but the maintenance is cost, so we still hope that you can support the legal version, resist piracy, buy legitimate products.Pirated products in use process will appear because of the use of inferior materials in function, affect the development efficiency, the following will give you the original merchants to buy links, and gives the pirated products of cheated (these stores often use a picture of the original, but is really fake goods, do not tally with the picture description).Original is not easy, thank you very much for your support!!
