Frequently Asked Questions Q1：There are many LoRa models (like E32, E22, and E220). How do I choose the right one? A：We have a full range of modules for different needs—E32 series supports 5-10km transmission, E22 series 5-7km, E220 series 7-10km with 22dBm/30dBm optional power. Simply tell us your application scenario, required transmission distance (indoor/1-3km industrial outdoor/5+km long range), and budget. Our engineers will recommend the most suitable and cost-effective model for you to test, avoiding unnecessary trial and error. Q2：We are sensitive to project costs. Can we get a bulk quote before testing? A：Absolutely. We understand that evaluating long-term costs is crucial. We offer transparent tiered volume-based pricing: 100-499 pieces get 10% off, 500+ pieces get 20% off (the more you buy, the lower the unit price). We support bulk quotes for a minimum order of 10 pieces and can provide a comprehensive bulk quote upfront so you can calculate your ROI accurately before starting any sample tests. Q3：How do your modules perform in terms of distance and anti-interference? A：Product stability is our top priority. All our LoRa modules adopt spread spectrum modulation technology with a receiving sensitivity as low as -148dBm, optimized for strong anti-interference. The maximum transmission distance reaches 10km in open ideal environments, and stable 1-3km data communication is guaranteed even in complex industrial environments with obstacles and signal interference. Q4：Do you provide datasheets, configuration software, and development codes? A：Yes, we provide comprehensive and updated technical resources (V2.0 and above) for all modules. You can easily download complete datasheets, host computer configuration software (support Windows/Linux systems), development materials, and programming examples for mainstream platforms (Arduino/STM32/ESP32) on our official website's technical center. All resources are available for instant download, which can speed up your integration process by over 60%. Q5：How long does shipping take to Europe and North America? A：We have over 200 SKUs of standard LoRa modules in stock year-round. We partner with top couriers like DHL, FedEx, and UPS (full order tracking available). Typically, your order will arrive at your facility in Europe or North America within 5 to 7 working days; some hot-selling models in our European and North American overseas warehouses can be shipped within 48 hours and delivered in 2-3 working days. Q6：How is customs clearance handled for international orders? A：We handle the export customs declaration from China (completed within 1 working day). You will be responsible for the import customs clearance in your country. To ensure a smooth and fast clearance process, we will provide all necessary documents including commercial invoices, and 12+ standard product certificates (CE/FCC/SRRC/MIC/KC/NCC/RoHS etc.), and also support the issuance of CO/Form A certificate of origin as required. Q7：What is your warranty policy to prove product quality? A：We are confident in our product quality and offer a 365-day official warranty (counting from the shipping date) for all LoRa modules. For non-human performance issues within the warranty period, we provide free repair or replacement with a 7-working-day repair cycle. For maintenance or replacements beyond one year, we only charge material costs (as low as $0.7-2.8 per piece) without any labor fees. Q8：We need a customized module (OEM/ODM). Can you guarantee the lead time? A：Yes. Ebyte has a 50+ in-house R&D team with strong customization capabilities. For regular OEM/ODM customization needs (hardware/software adjustment), we can finish R&D and prototyping within 2-4 weeks, and mass production (≥500 pieces) delivery within 1-3 weeks; for urgent customization demands, we can provide prototyping within 7 working days. We guarantee stable product quality and strict adherence to the agreed delivery schedules for all customization projects. Q9：What kind of technical support is available during our development phase? A：You won't be developing alone. We provide 7×24-hour professional technical support official email(service@cdebyte.com) — general technical issues will be responded within 1 hour, and complex issues (transmission stability/signal interference/software integration) will have a customized solution issued within 48 hours. We also assign a 1V1 technical engineer for your project to follow up the whole development process. Q10：Are there any ongoing promotions for new B2B testing? A：Yes! We are currently offering an Early Spring Sale for new B2B customers: 1) Free sample application: 1-3 pieces per IoT model for testing (free of product cost, only shipping fee); 2) Tiered bulk discount: 100-499 pieces get 10% off, 500+ pieces get 20% off, and the promotional price can be locked for 30 days. Submit an inquiry today to claim your free testing samples and lock in the promotional bulk rate—sample shipping also follows the 5-7 working days delivery standard to Europe and North America.
