About bluetooth module for arduino
Where to Find Bluetooth Module for Arduino Suppliers?
China remains the global epicenter for embedded electronics manufacturing, with Shenzhen-based suppliers dominating production of wireless modules such as Bluetooth-enabled components for Arduino platforms. The Pearl River Delta region hosts a dense network of component manufacturers, PCB fabricators, and firmware developers, enabling rapid prototyping and scalable assembly. This ecosystem supports just-in-time delivery models, with many suppliers operating vertically integrated facilities that encompass SMT (Surface Mount Technology) lines, RF testing chambers, and automated programming stations.
Suppliers in this segment leverage proximity to Tier-1 semiconductor distributors and logistics hubs like Shenzhen Bao’an International Airport, reducing component lead times by 20–35% compared to offshore alternatives. Most offer MOQs starting at 1 piece for sample validation, scaling efficiently to tens of thousands of units monthly. Average production cycles range from 7–15 days post-design approval, with express shipping options available for time-sensitive development projects.
How to Choose Bluetooth Module for Arduino Suppliers?
Procurement decisions should be guided by technical capability, transaction reliability, and scalability metrics:
Technical Specifications & Compliance
Verify module compatibility with target microcontrollers (e.g., ESP32, ATmega328P). Confirm adherence to Bluetooth standards (Bluetooth 4.2, BLE 5.0, or dual-mode operation) and compliance with RoHS and FCC regulations where applicable. Demand test reports for signal stability, power consumption under load, and interoperability across common Arduino IDE environments.
Production and Customization Capacity
Assess supplier flexibility through key indicators:
- In-house programming and flashing capabilities for pre-loaded firmware
- Support for custom pinouts, antenna designs, or compact form factors
- Availability of variants with integrated Wi-Fi, OLED displays, or LoRa transceivers
Cross-reference product listings with response times (target ≤4 hours) and on-time delivery rates (ideally ≥95%) to assess operational efficiency.
Transaction and Quality Assurance
Prioritize suppliers with documented quality management practices, including batch traceability and ESD-safe assembly lines. Use secure payment frameworks where funds are released upon shipment confirmation. Request physical samples to evaluate solder joint quality, labeling precision, and functional consistency before volume orders.
What Are the Best Bluetooth Module for Arduino Suppliers?
| Company Name | Main Products | Online Revenue | On-Time Delivery | Avg. Response | Reorder Rate | Customization Options | Min. Order Quantity | Price Range (USD) |
|---|---|---|---|---|---|---|---|---|
| Shenzhen Hechuang Lianying Technology Co., Ltd. | Drones Accessories, ICs, Power Supplies, Development Boards | US $10,000+ | 100% | ≤4h | <15% | Not specified | 1–10 pieces | $0.88–3.08 |
| Shenzhen Dahongxing Electronics Co., Ltd. | Wi-Fi/Bluetooth Modules, Development Boards, Power Supplies | US $200,000+ | 93% | ≤2h | 22% | Color, material, size, logo, packaging, label, graphics | 1–10 pieces | $0.50–2.00 |
| Shenzhen Zhicheng Electronic Technology Co., Ltd. | HC-Series, ESP32, Camera Modules, Wireless Shields | US $100,000+ | 95% | ≤2h | <15% | Color, material, size, logo, packaging, label, graphics | 10 pieces | $1.55–9.50 |
| Shenzhen Bluetech Technology Co., Ltd. | HC-05/HC-06, Wireless Encoders, RF Modules | US $70,000+ | 97% | ≤8h | 15% | Color, material, size, logo, packaging, label, graphics | 10 pieces | $0.58–5.90 |
| Chengdu Heltec Automation Technology Co., Ltd. | LoRa, Wi-Fi, IoT Development Boards, Sensors | US $20,000+ | 81% | ≤4h | 23% | Not specified | 1 piece | $4.90–17.90 |
Performance Analysis
Shenzhen Dahongxing and Zhicheng stand out for responsiveness (≤2h average reply time) and customization breadth, ideal for buyers requiring branded or form-factor-specific modules. Shenzhen Hechuang Lianying achieves perfect on-time delivery performance despite lower reorder volume, suggesting strong process discipline. Bluetech offers the widest price flexibility, with entry-level HC-series modules priced below $0.60 per unit at scale. Chengdu Heltec caters to high-end applications, offering premium ESP32-based boards with integrated peripherals but at higher price points and slightly lower fulfillment reliability (81% on-time rate). Buyers prioritizing cost efficiency should focus on suppliers offering sub-$1.00 HC-05/HC-06 variants with MOQs of 10 pieces.
FAQs
How to verify Bluetooth module supplier reliability?
Cross-check stated certifications (e.g., FCC, CE, RoHS) against product documentation. Request evidence of functional testing protocols, including RSSI stability and UART communication integrity. Analyze buyer feedback focusing on defect rates, firmware consistency, and post-purchase technical support.
What is the typical sampling timeline?
Standard samples ship within 3–7 days after order confirmation. Custom configurations involving firmware modifications or mechanical redesigns require 10–14 days. Air freight adds 5–8 days for international delivery.
Can suppliers provide pre-programmed modules?
Yes, many suppliers support factory loading of AT command sets, MAC address assignment, or pairing mode defaults. Confirm programming capabilities during initial inquiry, particularly for OEM integration.
Do suppliers support small-batch orders?
Most suppliers listed accept MOQs as low as 1 piece for evaluation. Unit prices decrease significantly at 10+ quantities, with steeper discounts beyond 100 units. This enables agile procurement for prototyping and iterative development.
How to initiate customization requests?
Submit detailed specifications including required dimensions, voltage tolerance (3.3V vs 5V logic), antenna type (PCB trace or external), and interface requirements (UART, SPI, I²C). Suppliers with customization tags typically respond with feasibility assessments within 24 hours.
