Where to Find Bluetooth Module Arduino Suppliers?
China remains the central hub for wireless communication module manufacturing, with Shenzhen and Chengdu emerging as key production clusters for Bluetooth modules compatible with Arduino platforms. Shenzhen's electronics ecosystem supports over 1,200 component suppliers within a 30km radius, enabling rapid prototyping and just-in-time delivery. The region specializes in compact RF modules integrating BLE 5.0, Wi-Fi coexistence, and low-power design, leveraging localized PCB fabrication and SMT assembly lines. Chengdu’s growing IoT-focused industrial base emphasizes R&D-driven development boards, offering integrated solutions that combine Bluetooth connectivity with LoRa or sensor interfaces.
These hubs benefit from vertically integrated supply chains—raw materials, chipsets (e.g., ESP32, CSR), and packaging are sourced domestically, reducing lead times by 25–40% compared to offshore alternatives. Average production cycles range from 7–14 days for standard orders, with MOQs as low as 10 pieces for small-scale buyers. Suppliers in these regions also offer scalability for high-volume procurement, supporting monthly outputs exceeding 500,000 units per facility. Cost efficiency is further enhanced by standardized testing protocols and automated burn-in procedures, ensuring consistent signal stability and transmission range across batches.
How to Choose Bluetooth Module Arduino Suppliers?
Procurement decisions should be guided by technical validation, operational reliability, and transaction security metrics:
Technical Compliance & Design Expertise
Confirm adherence to core standards: Bluetooth SIG certification, RoHS compliance, and FCC/CE EMC directives. Evaluate product specifications such as protocol support (BLE 4.2/5.1), UART interface compatibility, and power consumption profiles (e.g., <8mA in active mode). Prioritize suppliers offering detailed datasheets, AT command sets, and pinout diagrams tailored to Arduino IDE integration.
Production Capability Verification
Assess infrastructure maturity through verifiable indicators:
- Minimum factory area of 2,000m² indicating scalable operations
- In-house SMT lines with reflow soldering and AOI inspection
- Dedicated RF anechoic chambers for signal testing
Cross-reference on-time delivery rates (>90%) and response times (<4 hours) to gauge operational responsiveness.
Transaction Safeguards & Quality Control
Utilize secure payment methods with milestone-based release terms. Favor suppliers with documented QC processes including pre-shipment functional tests, ESD protection checks, and batch traceability. Analyze reorder rates as a proxy for customer satisfaction—rates above 25% suggest reliable performance and post-sale support. Request sample units to validate antenna efficiency, pairing latency, and firmware stability under real-world conditions before scaling orders.

Performance Analysis
Shenzhen-based suppliers dominate in responsiveness and customization agility, with three providers achieving sub-2-hour average response times and on-time delivery exceeding 92%. Shenzhen Zhicheng leads in punctuality (95%) and offers competitive pricing starting at $1.55 for shield modules. Chengdu Heltec distinguishes itself through higher-value development boards combining ESP32 with LoRa, targeting advanced IoT applications despite a lower on-time delivery rate. Shenzhen Hong Shu Yuan exhibits strong customer retention (30% reorder rate), suggesting robust quality control and technical support. For cost-sensitive prototyping, Dahongxing offers entry-level modules at $0.50/unit (10-piece MOQ), ideal for educational or hobbyist use. High-reliability industrial deployments should prioritize suppliers with proven RF shielding, stable firmware updates, and comprehensive documentation.
FAQs
How to verify Bluetooth module supplier reliability?
Cross-check compliance claims (RoHS, CE) with test reports and request samples for interoperability testing with common Arduino boards (Uno, Nano, Mega). Validate supplier credentials through transaction history, order fulfillment patterns, and third-party assurance programs.
What is the typical lead time for Bluetooth modules?
Standard orders are fulfilled within 7–14 days after payment confirmation. Custom configurations involving firmware modification or unique packaging may extend lead times to 21 days. Air shipping adds 5–7 days for international delivery.
Can suppliers customize Bluetooth modules for Arduino?
Yes, multiple suppliers offer customization in color, labeling, logo printing, pin layout, and firmware settings. Minimum order requirements vary from 10 to 100 units depending on complexity. Lead times for customized batches remain consistent with standard production schedules.
Do manufacturers provide free samples?
Sample policies differ: some suppliers offer paid samples refundable against future orders, while others charge full unit cost. Free samples are typically reserved for qualified buyers placing follow-up orders above specified thresholds.
What are common packaging and shipping options?
Modules are usually packed in anti-static bags with desiccants, shipped via express carriers (DHL, FedEx) for small parcels or consolidated sea freight for bulk orders. FOB Shenzhen is standard; CIF terms available upon request with destination port clarification.
