This module contains an EFR32MG22 wireless SoC, customer should buy a SLWSTK6021A (EFR32xG22 wireless starter kit) to do programming and debugging. Or, customers could outsourcing the design job to us.
There is a 10-pin connector, it has functions:
• Serial Wire Debug (SWD) with SWO
• Packet Trace Interface (PTI)
• Virtual COM port (VCOM)
• AEM monitored voltage rail
Phase 1: Requirements Analysis and Solution Design
The goal of this phase is to transform the client's vague concepts into actionable engineering specifications.
Key Tasks
1. In-depth Requirements Interviews: Clarify product functions, target cost, application scenarios, safety certifications, projected production volume, and lifecycle.
2. System Solution Design: Draw system block diagrams, define power architecture, main control chip, and communication interfaces, etc.
3. Project Timeline and Quotation: Provide a complete quotation including design fees, mold fees, prototyping fees, and mass production unit price, and jointly establish development milestones with the client.
Phase 2: Hardware Design
Key Tasks
1. Schematic Design: Draw a complete circuit diagram based on the specifications and perform signal integrity and power integrity simulations.
2. PCB Layout Design: Collaborate with structural engineers to define the board outline, hole positions, and height restrictions, and plan the placement of critical components.
3. Customer Confirmation and Archiving: Provide the final layout and wiring diagram and 3D simulation diagram to the customer for approval, and output production documents upon completion.
Phase 3: Rapid Prototyping and Functional Verification
Through rapid prototyping, produce the first prototype in the shortest possible time for functional testing.
Key Tasks
1. PCB Fabrication: Send Gerber Files to our own or partner PCB manufacturers for production.
2. PCBA Assembly: Perform SMT surface mount technology and necessary DIP insertion, including burning initial test firmware.
3. Customer Sample Delivery and Iteration: Provide test reports and samples, and modify the design based on customer feedback until the sample fully meets functional requirements.
Phase 4: Pilot Production Validation
Before mass production, small-batch pilot production is used to validate product maturity and process stability.
Key Tasks
1. Small-Batch Pilot Production: Typically involves producing 50-200 units, fully simulating the mass production line, fixtures, and testing processes.
2. Design Freeze: All pilot production issues are compiled for final revisions. After this, the design is generally frozen, and the project transitions to the mass production phase.
Phase 5: Mass Production and Shipment
Key Tasks
1. Mass Production: Integrate fully automated production lines to make PCBA.
2. Outgoing: Deliver the goods to the designated location according to the customer's requirements.
Phase 6: After-Sales Service and Continuous Optimization
Delivery is not the end, but the beginning of a long-term partnership.
