Where to Find Arduino Bluetooth Module Suppliers?
China remains the central hub for electronic module manufacturing, with Shenzhen and Chengdu emerging as key production clusters for Arduino-compatible Bluetooth modules. These regions host vertically integrated supply chains encompassing PCB fabrication, SMT assembly, and final testing—enabling rapid prototyping and scalable production. Shenzhen’s electronics ecosystem supports over 80% of global wireless module exports, leveraging proximity to component distributors and logistics gateways like Shekou Port for efficient international shipping.
The industrial clusters offer significant cost efficiencies, with localized sourcing of RF ICs, antennas, and passive components reducing material costs by 15–25% compared to non-Asian suppliers. Buyers benefit from flexible MOQs, ranging from single units for prototyping to bulk orders exceeding 10,000 pieces. Lead times average 7–15 days for sample batches and 20–30 days for mass production, depending on customization complexity and order volume.
How to Choose Arduino Bluetooth Module Suppliers?
Effective supplier selection requires rigorous evaluation across technical, operational, and transactional dimensions:
Technical & Compliance Verification
Confirm adherence to core standards including RoHS and CE for electromagnetic compatibility. While formal ISO 9001 certification is not universally listed, prioritize suppliers demonstrating structured quality control through documented testing procedures for RF output, signal stability, and power consumption. For BLE 5.0 or multi-master configurations, validate protocol compatibility with target microcontrollers via datasheets and firmware documentation.
Production and Customization Capacity
Assess scalability using available metrics:
- Suppliers with online revenues exceeding US $200,000 annually indicate established production throughput
- Customization capabilities in packaging, labeling, and firmware flashing are explicitly offered by select vendors
- In-house development boards and multi-functional modules (Wi-Fi + Bluetooth) suggest integrated R&D infrastructure
Cross-reference product diversity with response time and reorder rate to gauge operational responsiveness.
Transaction Reliability Indicators
Leverage performance data to mitigate risk:
- On-time delivery rates above 90% correlate with reliable logistics execution
- Reorder rates exceeding 25% reflect customer satisfaction and product consistency
- Response times under 3 hours ensure timely communication for technical queries and order adjustments

Performance Analysis
Shenzhen-based suppliers dominate in both responsiveness and revenue scale, with Shenzhen Dahongxing and Keyes offering the lowest entry barriers via sub-$1 pricing and 10-piece MOQs. Hanshuo stands out with a perfect 100% on-time delivery record and strong reorder activity (46%), indicating high buyer retention despite limited customization. Keyes combines reliability (99% on-time) with branding flexibility, making it suitable for private-label applications. In contrast, Heltec focuses on higher-value integrated solutions but exhibits lower delivery performance (77%), suggesting potential fulfillment bottlenecks. Suppliers with diversified portfolios—such as those combining Bluetooth, Wi-Fi, and LoRa—demonstrate greater technical depth, beneficial for IoT-centric projects requiring multi-protocol support.
FAQs
How to verify Arduino Bluetooth module supplier reliability?
Evaluate on-time delivery rates (target ≥90%), response speed (ideally ≤3 hours), and reorder frequency (≥25% indicates satisfaction). Request product specifications, test reports, or sample units to assess build quality and signal performance before scaling orders.
What is the typical MOQ and pricing for Arduino Bluetooth modules?
MOQs range from 1 piece for retail buyers to 10 pieces for discounted bulk purchases. Prices vary by chipset and functionality: basic HC-05 equivalents start at $0.50–$2.00, while BLE 5.0 or dual-mode modules reach $7–$12. Development-integrated boards may exceed $15.
Can suppliers customize Bluetooth modules for OEM use?
Yes, select suppliers offer customization in labeling, packaging, color, and firmware configuration. Shenzhen Dahongxing and Keyes explicitly list these services, enabling brand-specific integration for commercial deployments.
Do these suppliers support global shipping?
All listed suppliers operate on international B2B platforms with export experience. Shipping options include express carriers (DHL, FedEx) for samples and air/sea freight for large volumes. Incoterms such as FOB Shenzhen are commonly applied.
How to assess technical compatibility before procurement?
Request detailed datasheets covering operating voltage, baud rate, pin configuration, and supported profiles (e.g., SPP, HID). Test sample units with your target Arduino platform to confirm pairing stability, range, and AT command functionality prior to full-scale ordering.
