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.
ESP32-C3-DevKitM-01U is a compact development board designed by Espressif Systems, featuring the ESP32-C3 system-on-chip (SoC), which is powered by a single-core 32-bit RISC-V CPU. This development board provides a robust platform for developing IoT (Internet of Things) solutions, especially for scenarios requiring a small form factor and reliable wireless connectivity. The “U” in the name stands for the onboard IPEX connector for an external antenna, allowing enhanced flexibility and better wireless signal strength when using the board in environments with poor signal reception or where longer-range wireless communication is required.
The ESP32-C3-DevKitM-01U is ideal for applications in smart homes, wearables, industrial automation, and sensor networks. It is compatible with both Wi-Fi 4 (802.11b/g/n) and Bluetooth 5 Low Energy (LE), enabling reliable wireless communication across a wide range of devices.
Key features:
- RISC-V Architecture: The ESP32-C3 is equipped with a single-core 32-bit RISC-V processor that provides efficient processing power and low power consumption, perfect for energy-sensitive IoT applications.
- Wi-Fi and Bluetooth 5 Support: The board supports 2.4 GHz Wi-Fi and Bluetooth 5 (LE), making it suitable for both short and long-range wireless communications in IoT networks.
- IPEX Connector for External Antenna: Unlike other ESP32-C3 boards, the DevKitC-01U comes with an IPEX connector for an external antenna, which improves signal reception and transmission range, especially useful in areas with weak signals.
- Compact Size: The small form factor of the board allows it to be integrated into space-constrained environments while still delivering high performance.
- Low Power Consumption: Optimized for battery-powered applications, the ESP32-C3-DevKitC-01U excels in scenarios where power efficiency is a priority.
- Versatile GPIO: The board includes multiple general-purpose input/output (GPIO) pins that can be used for various applications, such as controlling sensors, motors, or connecting external devices via communication protocols like SPI, UART, and I2C.
- Compatible Development Environment: The ESP32-C3-DevKitC-01U is compatible with popular development frameworks, including ESP-IDF, Arduino, and other platforms, allowing developers to work with a wide range of tools and libraries.
