DFRobot Relay Shield 2.1 for Arduino
Description
- Completely new design capable of controlling 4 relays
- Compatible with Arduino UNO Rev3
- Each Relay has its own test button
- Supply Voltage: 9V
This DFRoobot Relay Shield for Arduino V2.1 is a completely new design which is capable of controlling 4 relays. The max switching power could be DC90W or AC 360VA. It could be directly controlled by Arduino/DFRduinothrough digital IOs with external 9v supply. With a built-in Xbee typesocket, it can be wirelessly controlled via Xbee/Bluetooth/WPM, making itan ideal solution for home automation and robotics purpose.
New Features
- Compatible with Arduino UNO Rev3
- Each Relay has its own test button to test the connection
- Standard DFRobot 3 Pin out
- Stackable
- XBee I/O direct control
- Compatible with Arduino Rev3
- 4 buttons to test module
- LED status indicator of relay
- Support Xbee IO directly control
- Xbee socket for wireless communication
I like this relay shield for the following reasons: - Opto-coupler on relays for better insulation - Indicator lights, and manual buttons for relays, convenient for testing. - Integrated design well done - Simplicity of implementation The negative points are: - Pine used unmodifiable (pine 2,7,8,10) - Need an external power supply to operate the relays. It's a shame to use pin 2 for output while this pin can be used with interrupts. Without adding a library, pines with interruptions are rather rare on an arduino.
J'aime bien ce shield de relais pour les raisons suivantes: - Opto-coupleur sur les relais pour une meilleure isolation - Témoins lumineux, et boutons manuel pour les relais, pratique pour les tests. - Design intégré bien fait - Simplicité de mise en oeuvre Les points négatifs sont: - Pin utilisées non modifiable (pin 2,7,8,10) - Besoin d'une alimentation externe pour actionner les relais. C'est dommage d'utiliser la pin 2 pour une sortie alors que cette pin peux être utilisée avec des interruptions. Sans ajout de librairie, les pins avec interruptions sont plutôt rare sur un arduino.
I used this on a mega with the mega breakout board. My complaint is that I wish it was mounted 180 degrees so the end of the board hung over another section of the breakout board. Otherwise the shield itself works nicely and offers flexibility.
Je l'ai utilisé sur un méga avec le conseil d'administration méga. Ma plainte est que je souhaite qu'il soit monté à 180 degrés de sorte que la fin du conseil pèse sur une autre section du panneau de discussion. Sinon, le bouclier lui-même fonctionne bien et offre une flexibilité.

- A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
- The RA number is valid for 30 days. The returned item must be received within that period.
- The RA number must be included with the return.
- Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
- Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A €100 cleaning fee may apply to domestic robots returned in used or unclean condition.
- A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
- Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
- Consumables * — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
- Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
- Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
- Build-it-yourself products and items requiring customer assembly * — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
- Digital Goods, Software, and Apps * — Final sale only, due to licensing restrictions.
- Clearance Items * — Products identified as clearance or final sale, including end-of-life or discontinued items.
- Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
- On-Demand Items * — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
- Professional & Specialized Equipment — See the Professional & Specialized Equipment Warranty page and Professional & Institutional Buyers (B2B) section in the Terms & Conditions.
* European consumers retain their statutory Right of Withdrawal on these items. Its exercise is subject to the conditions and exclusions set out in the Statutory Right of Withdrawal, and any reimbursement may be reduced to reflect a loss in value resulting from handling beyond inspection.
How to Request a Return Authorization (RA)
While the same return policy applies, these orders require a separate contact process for returns.
- RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets, or contact us through our Support Center.
- Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
