FAQ

Can the onboard 2.4GHz antenna be replaced?

The onboard 2.4GHz antenna is a fixed spring-type antenna. The board does not include an IPEX or SMA connector for external 2.4GHz signals, so replacement or extension is not supported by default.

  • Arduino
  • MicroPython
  • PlatformIO
  • Espressif IDE

We strongly recommend using Arduino. We provide complete technical support and offer a full set of libraries and examples for LoRaWAN development. 👉 LoRaWAN code for ESP32 Arduino framework

The board uses a standard SH1.25 x 2 battery connector. You can find compatible lithium battery packs by searching “SH1.25 x 2” online or in electronics stores.

  1. Please reinsert your USB cable, or try another cable that supports data transmission.

  3. Open your DEVICE MANAGER, select the port, and if prompted, install the required driver: 👉 CP210X driver

  4. Try another computer or a different operating system to rule out host-side issues.

  1. Open DEVICE MANAGER and check if the device port appears. If not, refer to the previous topic “I can’t find serial port”.

  2. Ensure the serial port is not occupied by another application.

  3. Enter BootLoader mode using one of the following methods:

    • Connect the USB cable, hold down the User (or ORG or Boot) key, press RST once, then release the User key.

    • Hold down the User (or ORG or Boot) key, then connect the USB cable.

To start the board manually: press and hold the Boot key, press RST once, then release the Boot key. The board includes 21 user-configurable buttons that can be mapped for custom functions or UI control.

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.
