We also made a plastic shell as an optional accessory. Which provide basic protection for the development board.

 


 

Onboard OLED Display

The integrated OLED display can be used to show some information such as system status and parameters, making it convenient for users to directly use the entire development board for their own product design.

FAQ

The 2.4GHz antenna is a spring antenna, and there is no additional interface on the board for 2.4GHz wireless signals.

No, the WiFi LoRa 32 don’t have an external PSRAM, if your application need use Bluetooth and Wi-Fi at the same time, you can look into this product: Heltec Wireless Bridge.

  • Arduino
  • Micro Python
  • Platform.io
  • Espressif IDE

We strongly recommend using Arduino. We have complete technical support and provide complete LoRaWAN code for ESP32 Arduino framework.

You can find this type of socket by search “SH1.25 x 2”.

Of course, you can contact our sales staff and provide your ideas.

No, the MCU is different.

It’s caused by the meshtastic setting. Changing the default screen to SSD1306 can solve the problem.

The specific steps are as follows:

“Radio configuration”→”Display”→”Override OLED auto-detect”→”SSD1306”

3. International Warehouse

Our products are stored in both our U.S. 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 U.S. Warehouse

For products stored in our warehouse in the U.S., 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.  

3.2 Chinese Warehouse

We will only arrange YunExpressexpress shipping from Shenzhen for orders with products in the Shenzhen warehouse worth more than €50. Orders directly shipped from our Shenzhen warehouse are handled by YunExpress. 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, the products will first be shipped from China to our U.S. warehouse and then shipped to the final destination. 

To ensure that your order is delivered within your desired timeframe, we recommend reviewing the warehouse information provided on the product pages before placing your order and selecting the appropriate shipping option. If you have any questions or need further assistance, please don't hesitate to contact our customer support team—we are here to help you!

For shipments delivered to customers in the United States, OpenELAB will clearly declare the value of the goods on the customs form in compliance with U.S. Customs and Border Protection (CBP) requirements. Depending on the product value and origin, certain orders may be subject to import duties, taxes, or brokerage fees upon arrival, which are the responsibility of the recipient unless otherwise stated.
 We aim to minimize delays and ensure compliance, but OpenELAB does not guarantee exemption from U.S. customs charges.
  

4.2 Are U.S. sales taxes included when the Customer places an order?

OpenELAB collects U.S. state sales tax where legally required. The applicable rate depends on the shipping address and will be calculated at checkout.
 If no sales tax is charged at the time of purchase, you may still be responsible for use tax according to your state’s tax laws. OpenELAB is committed to complying with the U.S. Supreme Court's decision in South Dakota v. Wayfair, Inc. and applicable local regulations.
  

4.3 Are there any other fees besides tax?

Apart from sales tax, OpenELAB may charge shipping or handling fees, which will be clearly displayed before checkout.
 Please note that international shipments to the U.S. may occasionally incur customs clearance charges or carrier-imposed fees (e.g., by DHL, FedEx, or USPS). These charges are not controlled by OpenELAB and may vary based on the delivery carrier and U.S. import classification.
