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.
The ESP32-S3-DevKitM-1 is an entry-level development board equipped with either ESP32-S3-MINI-1 or ESP32-S3-MINI-1U, a module named for its small size. This board integrates complete Wi-Fi and Bluetooth® Low Energy functions.
Most of the I/O pins on the module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-S3-DevKitM-1 on a breadboard.
Description of Components
The key components of the board are described in a counter-clockwise direction, starting from the ESP32-S3-MINI-1/1U module.
| Key Component | Description |
|---|---|
| ESP32-S3-MINI-1/1U | ESP32-S3-MINI-1 and ESP32-S3-MINI-1U are two general-purpose Wi-Fi and Bluetooth Low Energy combo modules that have a rich set of peripherals. ESP32-S3-MINI-1 comes with a PCB antenna. ESP32-S3-MINI-1U comes with an external antenna connector. At the core of the modules is ESP32-S3FN8, a chip equipped with an 8 MB flash. Since flash is packaged in the chip, rather than integrated into the module, ESP32-S3-MINI-1/1U has a smaller package size. |
| 5 V to 3.3 V LDO | Power regulator that converts a 5 V supply into a 3.3 V output. |
| Pin Headers | All available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board for easy interfacing and programming. For details, please see Header Block. |
| USB-to-UART Port | A Micro-USB port used for power supply to the board, for flashing applications to the chip, as well as for communication with the chip via the on-board USB-to-UART bridge. |
| Boot Button | Download button. Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port. |
| Reset Button | Press this button to restart ESP32-S3. |
| ESP32-S3 USB Port | ESP32-S3 full-speed USB OTG interface, compliant with the USB 1.1 specification. The interface is used for power supply to the board, for flashing applications to the chip, for communication with the chip using USB 1.1 protocols, as well as for JTAG debugging. |
| USB-to-UART Bridge | Single USB-to-UART bridge chip provides transfer rates up to 3 Mbps. |
| RGB LED | Addressable RGB LED, driven by GPIO48. |
| 3.3 V Power On LED | Turns on when the USB power is connected to the board. |
