M5Stack Dial v1.1 -1

M5Stack Dial v1.1 - ESP32-S3 Smart Rotary Knob with 1.28inch Round Touch Screen

39,55 €

M5Stack Dial v1.1 is a compact ESP32-S3 smart rotary knob controller with a 1.28-inch round touch screen, rotary encoder, RFID reader, and wide power input support. Based on official M5Stack documentation, the Dial v1.1 is designed for smart home control, IoT interfaces, access systems, and industrial control. For this product, the strongest optimization direction is Home Assistant control panels and smart home rotary interfaces, because the combination of touch, encoder input, screen UI, Wi-Fi, and compact wall-or-desktop form makes it especially suitable for local dashboards and scene control.

Official M5Stack materials also show a dedicated Smart Home GUI demo, wide DC 6-36V input support, battery interface, and expandable PORT.A / PORT.B connectivity. That makes the M5-K130-V11 a strong fit not only for Home Assistant dashboards, but also for room control panels, rotary media controllers, access control terminals, and custom HMI projects built with UiFlow2, Arduino, ESP-IDF, or PlatformIO.

Features

  • ESP32-S3 based smart rotary controller using the upgraded StampS3A core module
  • 1.28-inch 240 x 240 round touch display for compact HMI and dashboard interfaces
  • Rotary encoder + touch interaction for volume control, scene switching, menu navigation, and parameter adjustment
  • Built-in RFID reader based on WS1850S with 13.56MHz and ISO/IEC 14443 Type A / Type B support
  • Wide DC 6-36V input plus battery connector for embedded control and smart home deployments
  • PORT.A and PORT.B expansion for I2C and GPIO peripheral integration
  • Strong Home Assistant potential as a rotary smart home panel, room controller, and dashboard terminal
  • Multiple development paths through UiFlow2, Arduino IDE, ESP-IDF, and PlatformIO

  • Access control and RFID interaction for card-based triggering, identification, or check-in systems
  • IoT control terminals with Wi-Fi connectivity and external sensor or actuator expansion
  • Industrial HMI and rotary UI projects where compact display and physical interaction are both required
  • Media, audio, and parameter controllers for volume, mode, brightness, or custom device control

Packing List

  • Dial v1.1 x1
  • L-shaped 1.5mm hex key x1
  • 2.54-2P terminal x1

Other Content

The biggest practical advantage of the M5Stack Dial v1.1 is that it combines several interface methods in one very small device: touch display, rotary encoder, RFID, buzzer, and wireless connectivity. This makes it more useful than a simple screen module or plain encoder board when building local smart home controls, especially for Home Assistant style dashboards and scene selectors.

M5Stack also provides official software paths that make the device easier to deploy. The official UiFlow2 environment is suitable for rapid prototyping, while the Arduino library, ESP-IDF board support, and Smart Home GUI demo are better suited for deeper customization. This means the Dial v1.1 works both as a ready-to-demo smart home controller and as a serious embedded HMI development platform.

Important Notice:

  • Inventory Status: Please check the inventory status on the product page. Our system displays real-time stock for our Munich and Arlington 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 Arlington 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, Arlington, and Shenzhen warehouses to provide more flexible logistics solutions tailored to different regions and customer needs.
