Features of the LILYGO T-ECHO BME280

LILYGO T-ECHO BME280 integrates the high-performance L76K multi-satellite GNSS module, supporting GPS, BeiDou, GLONASS, and QZSS systems. This enables both multi-system joint positioning and single-system independent positioning, ensuring accurate and stable location tracking across diverse environments—from open fields to dense urban areas.

To enhance responsiveness, the module includes AGNSS (Assisted GNSS) technology, which significantly reduces the time required for the first positioning fix. This results in a faster and more reliable user experience, especially in mobile or time-sensitive applications.

Compared to traditional GPS-only modules, the L76K GNSS system in the LILYGO T-ECHO BME280 increases the number of visible satellites, improving positioning accuracy, signal stability, and tracking performance in areas with weak signal coverage. The integration of a low-noise amplifier (LNA) and surface acoustic filter further boosts sensitivity, enabling quick signal acquisition and precise location updates—even under challenging RF conditions.

For enhanced durability and reliability, the module includes an active antenna detection circuit and a protection circuit, safeguarding both the antenna and the board from potential damage or misconfiguration. These features make the LILYGO T-ECHO BME280 well-suited for outdoor deployments, mobile IoT nodes, and environmental monitoring systems.

To improve user interaction and visibility, the LILYGO T-ECHO BME280 is equipped with a 1.54-inch E-paper display featuring a 200×200 resolution and an integrated LED front light. This ensures clear readability in low-light or dark environments, making it ideal for both indoor dashboards and outdoor field use.

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.
