on March 6, The International Innovation Policy and Practice Conference was held in Shenzhen, China. Aiming to promote the establishment of the World Innovative Cities Cooperation Organization (WICCO) and build a platform for exchange, cooperation and resource-sharing among the world's leading innovative cities, this meeting brought together in Shenzhen mayors of some of the world's innovative cities, heads of famous technology enterprises, research institutes and venture capital institutions, and representatives of international organizations in China to discuss innovation, seek cooperation, and build an international innovation ecosystem.

Takasu Masakazu, a world-renowned maker, visiting lecturer of Waseda University, and partner of Switch Science Inc., elaborated on the development history and advantages of Shenzhen's hardware supply chain industry and introduced the characteristics of Shenzhen as the world's "Silicon Valley of Hardware". Notably, in his speech, Masakazu Takasu devoted nearly a quarter of his speech to introducing a Shenzhen-based open-source hardware company, M5Stack, to the audience.

What's so special about M5Stack, a company with such a strange-sounding name at first glance?  And why is it being showcased to represent Shenzhen-based open-source hardware companies?

Founded in 2015, M5Stack is a famous Shenzhen-based startup. In Japan, M5Stack is a popular presence among makers. There are 44 operation guide book books about M5Stack on the Japanese Amazon website, and many Japanese companies, universities and colleges use M5Stack for prototyping, validation, teaching and working.

Additionally, many makers all over the world have come to love M5Stack because of its plug-and-play, modular, adaptable, and stacking capabilities. M5Stack also partners with major companies in the industry like Microsoft, Sony, Ericsson, Amazon Web Services, Foxconn, and Siemens.

Link the World by Open Source - the Story of M5Stack

01 The idea

The story of M5Stack began with an idea from the founder Jimmy Lai. He was leaving Southern Grid and found a pile of discarded development boards in a drawer in his studio, which had become useless after having proven the product's functionality. In Jimmy’s opinion, these traditional development boards, with their exposed circuit boards and wires, were not only "crude" in appearance, but also complicated to operate and not conducive to further expansion.

And for individual developers, it can be costly in terms of time, effort and money to turn a rudimentary prototype based on a development board into a product that can be used in everyday scenarios.

"How about developing a modular development kit that could assist developers in swiftly developing and validating their concepts and working directly from idea to product," Jimmy Lai founded his company based on this notion.

02 Open source product system 

The "Stack" product, which has a modular design and a standard size of 5 cm by 5 cm, is plug-and-play, stackable, and extendable. Users can stack the modules with various functionalities to speed up product verification and development, and as a result, "M5Stack" was created. Today, M5Stack has 300+ SKUs, covering the full range of products from embedded controllers and communication modules to sensors, with high performance, reliability, scalability, and quick access to cloud platforms like Azure, and AWS.

03 A convenient graphical platform-UIFlow

Hardware development can be simplified by modular design, but software programming is still a challenge for most individuals. UIFLOW, a low-code graphical programming IDE, was introduced by M5Stack with this problem in mind to offer the greatest experience for prototyping IoT applications from entry-level hobbyists to experienced developers. With UIFLOW, a user can construct a solution out of a single block or use many blocks to achieve more complex scenarios. 

04 Community operations and rapid development

On social media platforms and communities, M5Stack always shares new ideas and real-time product development processes with the fans and makes quick adjustments based on the inspiration and feedback from the users. As a result, it has promoted a positive community culture, with many users regularly offering their thoughts, open-source projects, and practical advice. This has helped to shape what M5Stack is today.

IoT has reshaped our world in recent years as a technological revolution. With the development of IoT, M5Stack has gone through six years. The year 2022 is eventful. Here, we look back at the most important events of this year and express our sincere gratitude to our customers and friends.

01 Collaboration with Sony:Release of Atom Mate for toio™ in Japan

02 Collaboration with AWS:Launch of AWS IoT Edukit SimpleIOT Starter Bundle V1.0

Simple IoT, AWS's IoT workshop, provides free IoT programming knowledge and up-to-date code. Simple IoT ( is 100% open source, users can view and modify all data, code and services in their AWS account, and build their IoT projects with M5Stack's SimpleIOT Starter Bundle, an all-in-one package that allows people to start experimenting with a fully built and connected device in less than 5 minutes.

03 Collaboration with Microsoft: Launch of PnPFlow for Azure IoT Central Based on UIFlow

Project PnPFlow is the latest collaboration between M5STACK and the Azure IoT team. It provides a better collaborative experience for developers to build IoT plug-and-play devices without having to know the complexities of plug-and-play protocols and DTDL models. All they need to do is drag and drop blocks to build a business-centric application in UIFLOW. It is automatically provisioned on Azure IoT Central and works seamlessly with IoT Central's template-based web UI.

Christmas is celebrated by countries around the world. Traditions to celebrate the festival of love include a feast; giving gifts or cards; and enjoying church or public festivities, like singing Christmas carols and songs.

To celebrate the festival, Makers always show off their skills. In the M5Stack Christmas Contest 2022, M5 loyalists make a good performance. We hereby express our thanks to everyone who participated and helped make this contest a success! Let's see which ones came out on top from the 28 entries.

Magic Christmas Tree@IkeuchiRyota

 With a flick of the star wand, the Christmas tree lights up smoothly. Isn’t it like magic? In fact, it's based on the power of technology. Magnets are set underneath the Lego block with wires, Hall effect Unit is mounted on the bottom of the StickC console, when the star wand with iron inside connects to the magnet on the console, the lights on the Christmas tree start flickering as set before.

Chebyshev Linkage Robots @KantenNamako

 Its a comedy-style work with a mix of Asian and Western styles. To celebrate Christmas and new year, using M5Stack as the controller, Keiichi Matsui made two Chebyshev linkage (a four-bar linkage that converts rotational motion to approximate linear motion created by Chebyshev)robots. These two robots are decorated cutely, having a funny moving pace, conveying a happy atmosphere.

ATOM Christmas Tree@aaa_tu

 This Christmas tree stands out from the rest of the entries with its sense of technology and Minimalism. Just using M5ATOM Matrix and MAX7219 LED Display Module, @aaa_tu made this perfect project. The tutorial is uploaded on his website at 

Other Great Projects

M5stack Snow Ball@LuisLlamas

LuisLlamas is good at software interaction with M5Stack, making interesting projects. This time, Luis made a snowball with M5Core2, when the device turns direction, the snowflakes whirled down to the gravity direction gotten by the accelerometer in Core2, cute and vivid.

Displaying Air Quality CO2 Over Snowflakes @zeromem0

Zeromemo made a snowflake theme for Core2, a project that balances aesthetics and practicality. Hanged on a Christmas tree, this Core2 displays the time, temperature, CO2 concentration and ambient humidity information over snowflakes, presenting a festival atmosphere. Zeromemo uploaded the open-source code Github: 

Shake with ATOM S3@its_hard_2_name

As a Christmas gift from M5 to the engineers friends, the first batch of ATOMS3 went out of stock as soon as released. The author of this project, IAMLIUBO, is M5's leader test engineer. He made a interesting shaking game with ATOM S3’s built-inn IMU. LIUBO is also responsible for UIFlow 2.0. As he revealed, UIFlow 2.0 will be online before the Chinese New Year, stay tuned for it!
