AI-Powered supplier vetting

SummaryThe supplier is identified as a Shenzhen-based manufacturing factory in the manufacturing industry. It demonstrates broad customization, R&D, 3D design, SDK, ODM, and OEM capabilities, with new products reported in the past year. Quality assurance is stated, and finished-product inspection instructions are uniformly followed. However, several service-control procedures lack written records, there is no approved supplier list, and no valid manufacturing-capacity contract with associated subcontractors. The supplier has inventory capability and reported lead times within 15 workdays in both peak and off-season periods, but lacks overseas warehouses, showrooms, agents, or branches. Financial information is represented by year labels only, without sufficient evidence to assess financial credibility. No certification holdings or specific customer cases are provided.

Supplier typeThe supplier is classified as a combined company and a factory located in Bao’an District, Shenzhen, with associated companies in the manufacturing industry. This directly supports its identity as a manufacturing-oriented supplier rather than a purely trading entity.

R&D capabilityThe supplier reports professional technical R&D capability, available SDK support, new products within the past year, and ODM services. These stated capabilities provide explicit evidence of active product-development and technical-support capacity.

Production capacityThe supplier is a manufacturing factory, reports standardized and uniformly followed finished-product inspection instructions, has in-stock capability, and states lead times within 15 workdays in both peak and off-season periods. However, it has no valid contract with associated subcontractors, leaving subcontracted manufacturing governance as a documented weakness.

Customization capabilityThe supplier offers customization from samples and designs, full, minor, and flexible customization, as well as 3D software design, ODM, and OEM services. The consistency of these capabilities across the slices provides explicit evidence of broad customization support.

Product Q&A

Q:What frequencies are supported?

The receiver supports a wide range of frequencies including 360, 400, 433, 500, 530, 560, 720, 750, 868, 915MHz, and 2.4GHz.

Q:Is this receiver compatible with all ELRS heads?

Yes, it is compatible with any high-frequency head using the ELRS protocol, provided the frequency, firmware version, and linking password match.

Q:How do I bind the receiver to the transmitter?

Power on the aircraft three times quickly (within 1.5s intervals). When the light flashes rapidly, press the bind button on the remote control until the light turns solid.

Q:What is the refresh rate of this receiver?

The refresh rate ranges from 25Hz to 500Hz, depending on the specific frequency model, ensuring low latency for FPV racing.

Q:How can I update the firmware?

You can update the firmware via WiFi flashing mode. Power on the receiver, wait about 60 seconds for it to enter WiFi mode, and use the BelinRC software to flash.
