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 does this module support?

The module supports 433MHz, 500MHz, and 720MHz frequencies.

Q:How many power levels are available?

It supports 5 optional power levels: 100mW, 250mW, 500mW, 1000mW, and 2500mW.

Q:How do I adjust the transmission power?

You can switch power levels directly using the LUA scripts.

Q:Is this compatible with Radiomaster TX12?

Yes, this module is designed for use with the Radiomaster TX12.
