[Connector Selection Insight] Is There Still a Place for the Micro USB Connector? Yes—and It’s More Relevant Than You Think
Why Walta’s M30-0717-00045 Still Shines in Modern Designs
With USB Type-C becoming the new standard, many might assume that the Micro USB connector is on its way out. But the reality we see with customers is quite different—Micro USB still plays a crucial role, especially in designs where space, cost, and mechanical stability matter more than speed.
Today, we’re spotlighting Walta’s M30-0717-00045 Micro USB plug—a reliable, compact solution that continues to be a favorite in many engineering projects.
🧩 What is the M30-0717-00045 Micro USB Connector?
The M30-0717-00045 is a Micro USB Type B 5-pin plug designed for through-hole (DIP) mounting, providing strong mechanical stability and long-term durability in embedded systems.
📐 Key Features:
-
Total connector height of 1.8mm (including metal shell)—ideal for space-constrained layouts
-
DIP soldering for stronger board retention and structure
-
Metal shell with locking ears for better mechanical positioning
-
Available with 2D drawings and .STEP 3D models to simplify design integration
📦 Common Applications:
-
Wearable medical and fitness devices
-
Sensor and IoT modules
-
Custom development boards and test kits
-
Low-power or maintenance-oriented embedded systems
💡 Space-Saving Matters: When the Micro USB Connector Becomes the Deciding Factor
In compact product designs like wearables, handheld sensors, or IoT nodes, every millimeter counts. We’ve worked with customers whose layouts were pushed to the limit—only to find that a typical USB port simply wouldn’t fit.
That’s where the M30-0717-00045 truly shines. With its ultra-low height of 1.8mm and robust DIP legs, it provides a secure and efficient USB interface without compromising PCB layout or product form factor.
🤔 Why Not Just Use Type-C Instead of a Micro USB Connector?
It’s a fair question—we hear it all the time. But the answer is simple: “Don’t over-engineer what doesn’t need it.”
Not every product needs high-speed data or PD-level power. In many cases, USB is only used for firmware updates, charging, or basic data sync. In those scenarios, a Micro USB plug often makes more sense:
✅ Lower BOM cost—ideal for budget-sensitive projects
✅ Simpler structure—easier to solder and debug
✅ Universally available—field engineers and end-users still carry Micro USB cables
✅ Well-suited for low-speed, low-power applications
For development kits, maintenance ports, or single-function control boards, Micro USB is not outdated—it’s just practical.

🔧 Building a Custom Carrier Board? Why the Micro USB Connector Is a Secret Weapon
We’ve seen a growing number of customers designing their own carrier boards to integrate specific modules or chipsets. In these projects, space, port alignment, and mechanical stability are key concerns.
This is where the M30-0717-00045 really proves its value:
-
Height just right for stacked components
-
DIP structure + metal locking ears = strong physical fit
-
Full 3D model available = easy to drop into your CAD layout
One of our customers even told us:
“We tried a few options, but this connector just made our layout work.”
Sometimes, the right USB plug really does unlock the rest of the design.
✅ Final Thoughts: The Micro USB Connector Isn’t Obsolete—It’s Purpose-Fit
The M30-0717-00045 Micro USB connector represents a thoughtful, cost-effective design choice—not based on trends, but on fit.
It may not be flashy, but it’s reliable. It’s not the newest, but it works where it matters.
So next time you’re considering your USB connector options, don’t rule out Micro USB just yet—it might be the small solution you’ve been looking for.

【連接器選型觀點】Micro USB Connector 還有市場嗎？有，而且比你想的更重要
為什麼 Walta 的 M30-0717-00045 在現代設計中依然發光發熱
隨著 USB Type-C 成為新一代連接器標準，許多人可能會認為 Micro USB Connector 已經逐漸退出市場。但從我們與客戶的實際經驗來看，事實並非如此——Micro USB 仍在許多設計中扮演關鍵角色，特別是在空間有限、成本敏感、以及機構穩定性更重要的應用中。
今天要介紹的，是 Walta 的明星產品之一 —M30-0717-00045 Micro USB Plug，這是一款在眾多工程設計中持續受到青睞的可靠且精巧的連接器解決方案。
🧩 M30-0717-00045 Micro USB Connector 是什麼？
M30-0717-00045 是一款 Micro USB Type B 5Pin 插頭，採用 穿孔式（DIP）焊接設計，能為嵌入式系統提供優異的機構穩定性與長期耐用性。
📐 產品特點：
-
總高度僅 1.8mm（含金屬殼），適用於空間有限的板上佈局
-
DIP 焊接設計，有效提升板上固定力
-
金屬外殼附鎖耳，安裝定位更穩固
-
提供 2D 圖面與 .STEP 3D 模型，方便快速導入設計流程
📦 常見應用領域：
-
穿戴式醫療與健身設備
-
感測器模組與物聯網裝置
-
自訂開發板與測試板
-
低功耗或需維修孔位的嵌入式系統
💡 空間有限時，Micro USB Connector 就是關鍵差異
在如穿戴設備、手持感測器、IoT 節點等迷你產品中，每一毫米都至關重要。我們遇過許多客戶的 PCB 空間已壓縮到極限，標準 USB 接頭根本裝不下。
這時候，M30-0717-00045 就展現出它的優勢。它僅 1.8mm 的超薄高度，加上堅固的 DIP 焊腳，能提供可靠的 USB 連接，同時又不佔用過多板面空間或犧牲產品外型。
🤔 為什麼不直接選 Type-C？Micro USB Connector 不行嗎？
這是個合理的疑問——我們也經常被問到。但答案其實很簡單：不要為了不需要的規格，讓設計變複雜。
並非所有產品都需要高速傳輸或大功率供電。許多裝置使用 USB 僅僅是為了韌體更新、充電或基本資料同步，在這些情況下，Micro USB Plug 反而更合適：
✅ 成本更低 —— 非常適合成本敏感型產品
✅ 結構簡單 —— 更容易焊接與除錯
✅ 通用性高 —— 工程師與最終用戶幾乎都有 Micro USB 線
✅ 適用低速與低功耗設計 —— 剛好足夠，不多不少
對於開發板、維修孔、或單功能控制模組而言，Micro USB 並非過時，而是務實。
👉 想了解什麼時候該選 Type-C 嗎？
我們最近也針對這類情境發表了幾篇產品導向文章，歡迎參考：
深入了解 Type-C 如何應用於高階、耐用、與次世代設計中——當你的產品需要的不只是「基本款」。
🔧 自製載板？Micro USB Connector 是你的秘密武器
我們發現越來越多客戶會自行設計 Carrier Board（載板），以整合特定模組或晶片。而在這些專案中，空間配置、接點位置與機構穩定性，都是設計時的關鍵挑戰。
這正是 M30-0717-00045 發揮價值的地方：
-
高度剛好，可與堆疊式元件協同佈局
-
DIP 焊腳搭配金屬鎖耳，機構固定性優異
-
提供完整 3D 模型，可直接匯入 CAD 排板
我們的一位客戶甚至表示：
「我們試了幾個選項，最後這顆接頭讓整個 layout 都順了。」
有時候，選對一顆小小的 USB 接頭，真的能解決整個設計瓶頸。
✅ 總結：Micro USB Connector 並不是過時，而是合時合用
M30-0717-00045 Micro USB Connector 是一種理性且具成本效益的選擇，不是追求流行，而是為實際設計需求量身打造。
它不一定最新，但絕對可靠。它不搶眼，卻在關鍵時刻發揮最大效益。
所以下次你在評估 USB 接頭時，別急著將 Micro USB 排除在外——它可能正是你要找的那個「剛剛好」的解決方案。
