Client Value

Whoever You Are, There’s a Path Here for You

Three client profiles, three ways of working. Switch tabs to see how we solve your core problem.

Amazon / AliExpress / TEMU / DTC sellers

Cross-border E-commerce Brands

You want differentiated products, but have no hardware R&D team, fear me-too molds, and race against platform season peaks.

Lighting / small-appliance / plastics manufacturers

OEM Factories With Capacity

You have lines and workers, but no electronic R&D. Orders walk away when clients bring solution requirements.

How MJX Helps

  • Full R&D coverage: schematic + PCB + firmware + test — you focus on manufacturing
  • Clear boundary: IP transferable/licensable. We never build finished goods or poach your clients
  • DFM review, fixture & flying-probe test plans for high first-pass yield
  • BOM cost-down and sourcing support to win sharper quotes

Second Source for Big Brands

New business lines refuse single-supplier risk. They need a technically solid, fast, capacity-controlled second source.

How MJX Helps

  • Mature robot platform (motion control / sensor fusion / app) shortens in-house development
  • Dual-source safety: complete documentation, auditable code, alternate-BOM plans
  • NDA-first confidentiality; on-site joint debugging supported
  • Elastic capacity: pilot validation → ramp-up, aligned to your milestones

FAQ

Before We Start, You May Ask

Is MJX a solution provider or a factory? Do you sell finished products?
MJX is an MCU chip solution provider and PCBA design house. We build solutions only — never finished goods: no mass production of end products, no retail, no consumer brand of our own, so we never compete with clients. We own schematics, PCB, firmware, app and compliance; you own product definition, sales and brand.
What is your MOQ?
Ready-made supply: 500–1,000 boards; light customization: no threshold for prototypes (3–5 units), pilot runs from 300–1,000 units; robot programs are project-based. Low-volume pilots are genuinely welcome — scale after validation.
What’s the typical development timeline?
Light customization (housing/parameters): 7-day evaluation, 20–35 day prototypes, 30–45 day pilot; deep customization (with app): 60–90 days; robot platforms: first build in 45–70 days. Start 60 days before peak season.
Who owns the IP?
Light customization includes a usage license; buyout agreements transfer schematic, PCB source and firmware source in full. In all models, your product definitions and sales data remain 100% yours.
What do you need for a quotation?
Tell us: ① product type with reference sample/link; ② desired differentiators; ③ expected annual and first-batch volumes; ④ target markets (compliance). Assessment and quote typically within 1–3 business days.
Do you support certifications (CE/FCC/UL/RoHS)?
Yes. Designs follow target standards from day one (creepage, flame-retardancy, EMC), and most categories have reusable certification templates. Independent certificates are supported via partner labs in ~3–6 weeks.
