Explore Scope and Deliverables →Project Inputs
Information is used to determine interfaces, implementation conditions, and scope of work.
- Existing motherboard interfaces, voltages, connectors and space dimensions
- Wi-Fi chip, frequency bands, SDK and network provisioning interface
- Cellular module models, firmware, interfaces and power supply peaks
Deliverables and Acceptance
- Delivery Documentation
- Communication board design information, firmware and interface test records, networking firmware, message specifications, configuration examples and disconnection test records, driver or adaptation code, network configuration and target operator environment test records.
- Versions and Reproducibility
- The delivery list records the target hardware, software version, build or deployment steps, interface configuration and test records to facilitate subsequent integration testing and maintenance.
- Check pin definitions, logic levels and transmit and receive timings
- Test network provisioning, renetworking, and error credential handling
- Verify network registration, dial-up or data connection and business reporting
The acceptance is carried out based on the equipment, version, environment, samples and indicators confirmed by both parties; the scope of source code and design documents, prototype materials, third-party fees and subsequent maintenance are listed in the project documents.
Frequently Asked Questions
Can I delegate only one of the development modules?
Yes. RS-485, CAN and Ethernet Communication Board Development, Wi-Fi Device Connectivity and MQTT Integration, 4G and NB-IoT Module Connectivity Development can be scoped separately. Define the interfaces and integration responsibilities between modules before development.
Does adding a communication board require changes to the main board?
An add-on board can be evaluated when interfaces, power capacity and mounting space are available. Otherwise, the main-board interface or mechanical design may need changes. Schematics and prototypes establish the modification scope first.
