Project Background

With the rapid growth of IoT and the sharing economy, the demand for high-precision, low-power, and compact positioning modules has increased significantly. This project required a highly integrated tracker mainboard that can be used as a standalone device or embedded into other equipment for asset tracking, vehicle security, pet tracking, and other applications.

Key Hardware Requirements:

• Multi-Mode Positioning: GPS, BeiDou, LBS (base station), WiFi, and AGPS

• Global Connectivity: GSM/GPRS quad-band (850/900/1800/1900MHz) for global deployment

• Low Power Consumption: Support for sleep modes to extend battery life

• Compact Size: High-density integration for space-constrained applications

• Rich Interface: Support for external sensors, relay control, and expansion

• Alert Functions: Vibration, movement, over-speed, and low-battery alerts

Our PCBA Solution

We designed a highly integrated tracker module PCBA based on the MediaTek MT2503 platform — a proven solution combining high performance with low power consumption for tracking applications.
