Product definition, hardware design, measurement, field validation and manufacturing preparation are connected into one development path.
02
Design custom hardware
Integrate compute, sensors, power, RF, protection and connectors around the real product.
03
Prototype and measure
Verify rails, current, communication, sensing, charging, thermal behaviour and failure conditions.
04
Pilot in the field
Validate range, battery use, installation, environmental exposure and diagnostic behaviour.
05
Prepare for production
Close DFM, DFT, programming, calibration, test access, sourcing and manufacturing handoff.
Why product teams choose PCB Must
Hardware decisions stay connected to the product outcome.
We focus on the physical device and the boundaries it must provide to firmware, application, cloud and manufacturing teams.
Field-first reliability
Power, interfaces, protection, environment and diagnostics are considered around real use—not only bench operation.
Power engineering with evidence
Battery targets include operating states, radio peaks, retries, leakage, conversion losses and temperature.
Connectivity as a system
Technology, antenna, enclosure, ground, provisioning, infrastructure and service cost are planned together.
Production-ready thinking
Programming, calibration, test access, DFM, DFT and BOM risk are addressed while change is still practical.
Clear integration boundaries
Responsibilities across hardware, firmware, mobile application and cloud remain visible and reviewable.
Editable source-file ownership
Complete design and manufacturing files can be transferred to the approved engineering or manufacturing partner.
End-to-end IoT hardware development services
The electronics needed to move beyond a development kit.
Each service is tied to a specific product decision, risk or release outcome.
Architecture
Product architecture and feasibility
Define use cases, operating states, data flow, interfaces, security boundaries, connectivity, power and product risks before detailed design.
Outcome: a credible development plan.
Custom electronics
Circuit and PCB design
Develop compute, sensors, power, charging, protection, storage, connectors and multilayer PCB around the final product constraints.
Outcome: compact prototype-ready hardware.
Wireless
BLE, Wi-Fi, LoRa and cellular integration
Select connectivity around range, data, battery, infrastructure, regional requirements and ownership cost—not module popularity.
Outcome: connectivity that fits the deployment.
Power
Battery, charging and low-power design
Model sleep, sensing, processing, radio connection, retries, charging, conversion loss and thermal limits across the operating cycle.
Outcome: a measurable battery-life target.
Prototype
Bring-up, debugging and validation
Measure power, sensors, RF, charging, interfaces, temperature and failure response before the product is released.
Outcome: evidence for the next revision.
Production
DFM, DFT and manufacturing support
Prepare programming, test access, calibration, first-article review, component alternatives and production handoff.
Outcome: a repeatable manufacturing package.

One product architecture
Discuss Your IoT Product →
Device hardware, connectivity and product operations must agree before the PCB is frozen.
A radio choice changes the power budget. The enclosure changes antenna behaviour. The reporting interval changes battery life. Manufacturing changes test access. These decisions cannot be designed independently.
✓Device layer: sensors, compute, storage, power and actuators
✓Connectivity layer: BLE, Wi-Fi, LoRa, cellular or Ethernet
✓Service interface: provisioning, identity, data model, OTA boundary and diagnostics
✓Operations: programming, calibration, fleet visibility, support and manufacturing
What the deployed product must survive
Reliability is designed through sensing, power, connectivity, security and recovery behaviour.
Each visual represents a system boundary that must be resolved before the hardware is considered field-ready.
Sensing
Accurate measurement from the physical input to product data
Protection, filtering, conversion, timing, calibration and diagnostics must operate as one signal chain.
Field behaviour
Defined response when power, network or environment degrades
The device needs safe degraded modes, offline behaviour, useful diagnostics and a recoverable path.
Security and support
Clear ownership of identity, provisioning, debug and updates
Hardware, firmware and service responsibilities must be explicit enough to secure and support the device.

IoT product development FAQ
What product teams need to know before starting.
Can you start from an IoT product idea?
Yes. The first phase converts the idea into measurable requirements, architecture options, technical risks and a phased development plan before detailed hardware design begins.
Can you replace a development kit with a custom PCB?
Yes. The custom board can retain the required compute and connectivity while integrating the final power system, sensors, antenna, interfaces, connectors and enclosure constraints.
Which wireless technology should the product use?
The decision depends on range, data volume, battery, infrastructure, installation, region, certification and total ownership cost. The best choice is made around the complete deployment.
Can you design battery-powered IoT hardware?
Yes. The energy model includes sleep current, duty cycle, sensor warm-up, processing, radio peaks, retries, charging and conversion losses.
Do you develop the mobile app and cloud platform?
PCB Must leads the electronics and hardware development. App, cloud and firmware implementation can be handled by the client or software partners, with interfaces and ownership boundaries clearly defined.
Can you support industrial IoT products?
Yes. Industrial work can include protected power, robust or isolated interfaces, sensors, relays, Ethernet, wireless connectivity, field buses and environmental constraints.
Does the scope include prototypes and testing?
Yes. The engagement can continue through prototype coordination, bring-up, measurements, design corrections, field-condition testing and production-readiness support.
How is security handled?
Hardware security boundaries, device identity, debug access, secure storage, provisioning and update interfaces are defined with the firmware and service architecture.
What affects cost and schedule?
Product complexity, sensors, wireless technology, battery target, enclosure, compliance needs, prototype iterations, software integration and production quantity are the main drivers.
