About arduino uno r4 wifi manufacturer
Where to Find Arduino Uno R4 WiFi Manufacturer Suppliers?
China remains the central hub for microcontroller and development board manufacturing, with key production clusters in Shenzhen and Guangzhou enabling rapid prototyping and scalable output. These regions host vertically integrated supply chains that support efficient sourcing of components such as RA4M1 microcontrollers, ESP-32 modules, and Wi-Fi-enabled MCUs. The proximity of PCB fabricators, firmware developers, and logistics providers within a 50km radius allows for agile production cycles and faster time-to-market.
Suppliers in this ecosystem typically operate lean manufacturing lines optimized for low to mid-volume orders, with average monthly capacities ranging from 5,000 to 20,000 units per facility. Most leverage surface-mount technology (SMT) assembly and automated testing protocols to ensure consistency across batches. Buyers benefit from competitive pricing—driven by localized component access—and flexibility in MOQs, often starting at 1 piece for sample validation. Lead times for standard orders range from 7–15 days, with express shipping options available for global distribution.
How to Choose Arduino Uno R4 WiFi Manufacturer Suppliers?
Selecting reliable partners requires adherence to structured evaluation criteria:
Technical Capability Verification
Confirm compatibility with official Arduino Uno R4 specifications, including Renesas RA4M1 MCU integration and onboard Wi-Fi/BLE via ESP-32 module. Suppliers should provide schematic documentation and firmware details upon request. Cross-check product listings against known reference designs to identify clones or modified variants.
Production & Operational Metrics
Assess operational efficiency using measurable indicators:
- On-time delivery rate exceeding 90% indicates logistical reliability
- Response time under 8 hours reflects active account management
- Reorder rates above 18% suggest customer satisfaction and product consistency
Prioritize suppliers with documented quality control processes, even if formal certifications are not listed.
Transaction Risk Mitigation
Utilize secure payment methods with escrow functionality to protect against non-delivery or specification mismatches. Request physical samples before bulk ordering to validate build quality, pin alignment, and wireless functionality. Conduct basic firmware upload tests to verify bootloader integrity and USB-C communication stability.
What Are the Best Arduino Uno R4 WiFi Manufacturer Suppliers?
| Company Name | Main Products | Online Revenue | On-Time Delivery | Avg. Response | Reorder Rate | Min. Order Quantity | Price Range (USD) |

Performance Analysis
Guangzhou Zhongchuang Youpin and Shenzhen Chengsuchuang lead in transaction volume and responsiveness, both reporting over US $20,000 in online revenue and on-time delivery rates of 100%. Shaotou Xiangming stands out for its sub-2-hour response time, making it suitable for urgent procurement cycles despite lower reorder activity. Guangzhou Little Sesame demonstrates strong buyer retention with a 36% reorder rate, suggesting consistent product performance despite a slightly lower on-time delivery score. Pricing varies significantly—ranging from $4.79 for RP2040-based alternatives to $85 for specialized Wi-Fi-enabled boards—highlighting the importance of technical due diligence to avoid misaligned specifications.
FAQs
Do these suppliers manufacture genuine Arduino Uno R4 WiFi boards?
No supplier data confirms official licensing from Arduino LLC. Most offer compatible or clone versions based on similar architectures (e.g., RA4M1 or ESP-32). Buyers seeking authentic units should verify compliance with Arduino’s open-source hardware standards and check for official branding restrictions.
What is the typical minimum order quantity?
MOQs are highly flexible, with four of five suppliers accepting single-piece orders. Some kit-based listings require minimums of 2–10 units. This enables cost-effective sampling and small-scale deployment without large upfront commitments.
Can suppliers customize firmware or hardware configurations?
Yes, many suppliers support modifications such as pre-flashed firmware, custom bootloaders, or added peripherals (e.g., sensors, displays). Technical feasibility must be confirmed through direct inquiry, along with potential impacts on lead time and unit cost.
Are there quality certifications like ISO or RoHS?
Certifications are not explicitly stated in the provided data. However, consistent on-time delivery and repeat order metrics suggest adherence to internal quality controls. Buyers requiring compliance with RoHS, CE, or ISO 9001 should request documentation prior to order placement.
How long does shipping take internationally?
Standard air shipping takes 7–14 days depending on destination. Express couriers (DHL, FedEx) reduce transit time to 3–6 days. For orders exceeding 100 units, sea freight becomes economically viable but extends delivery to 25–35 days.
