About Us
REDCOAST.LTD is a high-end smart IoT company that develops its own hardware — including custom PCB and board-level design — together with an in-house web platform and iOS/Android apps, delivering end-to-end hardware-plus-software solutions with flexible power and connectivity.
A Team That Owns the Whole Project
REDCOAST.LTD is a custom Smart IoT company that develops its own hardware. We design and build our own PCB and board-level hardware to fit each project — combined with our in-house management platform, mobile apps, deployment and maintenance — into deployable industry solutions: hardware plus software, owned end-to-end by a single team.
Headquartered in Yangzhou, Jiangsu, China, we are a smart IoT company made up of engineers with strong hardware and software backgrounds. When a project needs it, we develop custom PCB and board-level hardware in-house, rather than forcing an off-the-shelf board to fit.
We do focus on the product level: custom PCB and board-level hardware, our own platform and apps, and end-to-end delivery. We do not fabricate chips, modules or low-level semiconductors, and we do not make consumer electronics — every project is shipped end-to-end by a single accountable team, so customers never get stuck between vendors.
Our edge is "engineered for your project" — custom hardware and software, not "an old solution with a new logo".
Scope
What We Do / Don't Do
A clear boundary is worth more than a long list of buzzwords.
What we do
- Custom PCB and board-level hardware development — designed in-house per project
- IoT solution design and end-to-end project delivery (hardware + platform + apps)
- In-house web management platform development and customization
- iOS / Android app development and publishing
- Integration, customization and ongoing maintenance with your existing systems
- Worldwide deployments and after-sales support
What we don't do
- Chip, module or semiconductor fabrication (we design boards, not silicon)
- Consumer-grade smart products
- Software-less projects (every project pairs hardware with platform or apps)
Capabilities
Four Pillars
The four directions that back our delivery — all owned by our own team.
Custom Hardware Development
In-house PCB and board-level design for IoT sensing, control and management. Power options across grid, solar, hybrid and battery. Connectivity over 4G/5G, NB-IoT, LoRa, WiFi and Ethernet.
In-house Web Platform
Multi-tenant, multi-organization device management with fine-grained roles, dashboards, large-screen visualization, reporting and per-industry customization.
Native iOS / Android Apps
Native apps with QR scan, Bluetooth, push and offline cache. White-label friendly and tied into the platform permission model.
Integration & APIs
REST API, MQTT and WebSocket interfaces; custom protocol support; SSO and OAuth — so we integrate cleanly with your existing systems.
Technical Capability
A Flexible, Composable Stack
From power and connectivity to deployment environment, we compose the stack to fit each site — so the solution truly matches the scenario.
Power Options
Grid Power
Standard grid connection for urban and park sites with existing power.
Solar Power
PV panels with storage for remote sites without grid access.
Grid-Solar Hybrid
Grid-primary with solar backup, balancing stability and energy cost.
Wind-Solar Hybrid
Wind plus solar for outdoor environments with variable climate.
Battery Storage
Battery backup for continuous operation during outages.
Connectivity
Cellular
4G / 5G — high-bandwidth, wide-coverage primary connectivity.
LPWAN
NB-IoT / LoRa — ultra-low power for massive distributed endpoints.
Wired
Ethernet for stable, reliable fixed-site access.
Short-range
WiFi for local device networking and on-site commissioning.
Deployment Environments
How We Work
A Transparent Four-Step Process
From discovery to operation — every step is spelled out, written into the contract, and delivered as promised.
Discovery
We learn your background, scale and compliance needs, then provide a free initial proposal and feasibility assessment.
Solution Design
We finalize hardware, power and connectivity, platform features and app UX, with a clear quote and timeline.
Build & Deliver
Hardware procurement, platform customization and app development run in parallel, with milestone reviews.
Launch & Support
After go-live we keep providing maintenance, secondary development and version upgrades.
Engagement Models
Three Flexible Ways to Work With Us
Whether a one-off project, a standardized solution, or secondary development on an existing system — there is a model that fits.
Integration Project Delivery
Custom per-project delivery — one-time payment plus maintenance, owned end-to-end from hardware to apps by one team.
Packaged Hardware-plus-Software
Proven scenarios distilled into standardized solutions (with platform and apps) for fast, repeatable deployment.
Platform / App Secondary Development
Ongoing iteration on delivered systems: new features, third-party integration, support for new hardware.
What We Stand For
Three Things That Matter More Than Slogans
We earn trust through real commitments — not marketing.
Honesty
Quote, timeline, scope, and what we cannot do — all spelled out before signing. We do not put commitments we can’t keep into contracts.
Focus
We only take IoT integration projects we can deliver well. Fully committed per project, from first call to long-term support.
Responsiveness
4-hour business-day response. Major issues escalated remotely or on-site within 24 hours.
