For Engineers Who Love Open Source Hardware
Hello, fellow geeks!
I’m an embedded systems engineer with a degree in IoT Engineering, and I’ve been deeply involved in AIoT product development for years. I’ve participated in several B2B projects from the ground up — covering open-source hardware, system architecture, hardware selection, and solution implementation.
Through this journey, I’ve come across all kinds of AIoT products.
Some are smart, efficient, and elegantly designed; others are overcomplicated, packed with features that don’t solve real problems.
Over time, I’ve started focusing on one simple but important question:
Does this product truly solve the user’s core need?
Not just whether it’s ‘cool’ or uses the latest tech.
I firmly believe that great products don’t have to be complex or expensive — they just need to solve problems clearly and effectively, at a reasonable cost.
That’s why I created this site:
A space where engineers can connect, share, and learn from each other.
Here, I share great products and smart solutions I’ve encountered during projects — and try to explain why they’re good.
This isn’t about marketing. It’s about real experience, honest judgment, and technical clarity.
This platform is called sharingwin, because I believe in shared success.
You’ll find high-value, practical tools and products here — to help you save time on selection, avoid unnecessary trial and error, and focus on what works.
As for me, I hope to use this space to connect with like-minded engineers, exchange ideas, and — to be honest — maybe earn a little on the side too. That’s part of the fun. 😄
To all the makers and creators who’ve supported me along the way — thank you.
Due to some heavy personal projects recently, I haven’t been able to update or engage as frequently as I’d like — and for that, I apologize.
Moving forward, I’ll continue to optimize product content and be more active in sharing useful insights.
Your trust and support mean everything.
You’re the reason I believe this platform matters.
If you have any great products or ideas you think deserve more visibility, feel free to reach out.
I’m happy to help with sourcing, connect to the right supply chain, or feature it here so more engineers can see its value.
A single person has limited power —
but co-creation multiplies value.
If you believe in that too, let’s build something useful and meaningful — together.

-
PS Pin: Connect the PS pin to ground. After power-down and restart, the module will enter I2C mode. In this mode, the customer can directly operate the sensor. The module’s MCU will not interact with the sensor, ensuring no power consumption from the MCU.
-
TTL Level: The module uses TTL level (1/0), which can be directly connected to a microcontroller’s UART or chips such as CH340, FT232, etc. However, it should not be directly connected to a computer’s 9-pin serial port.
