DFRduino UNO R3 - Compatible with Arduino Uno

13,55 €

The DFRduino UNO V3.0 from DFRobot is a compact physical computing board ideal for both academic use and development. It is a microcontroller board fully compatible with Arduino UNO R3 and the Arduino IDE open-source development environment, which supports the Processing / Wiring language.

You can use it to build stand-alone interactive objects or connect it to software on your computer (such as Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free and supports Mac OS X, Windows, and Linux.

 

Board Features

This board uses the ATmega16U2 as a USB-to-serial converter and retains the DIP package AVR Chip (ATmega328), allowing for easy reprogramming or replacement.

A key feature of this board is the use of color-coded headers for different I/O port types:

  • Red for Power Section

  • Blue for Analog I/O

  • Green for Digital I/O

These colors match DFRobot’s sensor cables, making it easier to identify where to connect sensors and distinguish between Analog and Digital pins.

Important Notice:

  • Inventory Status: Please check the inventory status on the product page. Our system displays real-time stock for our Munich and Long Beach warehouses. If an item is out of stock in these locations, it will be marked as "Pre-order". You can still place an order for these items.
  • Pre-order Fulfillment: For "Pre-order" items, we arrange the most efficient logistics solution to ensure you receive your goods as quickly as possible. Your package may be shipped directly from our Shenzhen warehouse. Alternatively, as part of our standard restocking process, we may transport the goods to our Munich or Long Beach warehouse first (typically taking 5-10 business days) before dispatching them to you.
  • Split Shipments: If your order contains both in-stock and Pre-order items, we will prioritize shipping the in-stock items from the local warehouse immediately. The remaining Pre-order items will be sent to you in a separate shipment once they are ready.

3. International Warehouse

Our products are stored in our Munich, Long Beach, and Shenzhen warehouses to provide more flexible logistics solutions tailored to different regions and customer needs. On each product's description page, we indicate the specific warehouse location to help you better plan your purchase and delivery schedule.

3.1 German Warehouse

For products stored in our warehouse in Munich, we use either Deutsche Post or DHL for shipping, depending on the size of the package. Logistics within Germany are very efficient, with an estimated delivery time of 2-4 business days, ensuring you receive your order quickly and conveniently. For Western EU countries, the estimated delivery time is 4-6 business days. For Eastern EU countries, the estimated delivery time is 6-8 business days.

3.2 US Warehouse

For products stored in our warehouse in Long Beach, we use either USPS or UPS for shipping, depending on the size of the package. Logistics within U.S. are very efficient, with an estimated delivery time of 3-7 business days, ensuring you receive your order quickly and conveniently.

3.3 Chinese Warehouse

For Pre-order items or orders fulfilled directly from our Shenzhen warehouse, we utilize YunExpress for reliable international shipping. Given the complexities of international shipping, the estimated delivery time for these packages is around 10 business days, though this may vary slightly due to customs processes or other uncontrollable factors. Otherwise, products will be restocked to our Munich or US warehouses before final delivery, as detailed in the "Important Notice" above.

4. Customs and Taxes

4.1 How are customs handled by OpenELAB for import or export?

For EU Member States: Whether shipped from Germany or China, we cover all import duties and taxes (DDP), ensuring that you receive your package without any additional costs or hassle with customs.

Important Exception for Non-EU Countries (e.g., Switzerland, Norway):
For countries outside of the European Union, such as Switzerland and Norway, you may be subject to import duties, taxes, and/or customs fees charged upon delivery. These fees vary from country to country and are the sole responsibility of the recipient.

⚠️ Refusal of Delivery: If you refuse to pay these fees upon delivery and the package is returned to us, the refund amount will be calculated after deducting the original shipping costs, return shipping costs, and any applicable customs or storage fees.

4.2 How is VAT charged when the Customer places an order from OpenELAB?

In accordance with the newest VAT e-commerce rules in the EU, OpenELAB shall have the right to charge the amount of VAT at checkout. The standard rate of actual VAT applied is subject to the destination country's regulations. No additional VAT will be charged upon delivery for these orders.
