README
README.md4G communication and GPS tracking device
This is a device that is suitable for IoT and machine-to-machine communication. SIM7600E is an industrial-grade LTE Cat 1 module designed for global IoT and M2M applications. It supports 4G LTE-FDD/TDD, 3G (UMTS/HSPA+), and 2G (GSM/GPRS/EDGE), delivering maximum download speeds of 10 Mbps and upload speeds of 5 Mbps
Features
Cellular Connectivity: LTE Cat-4 provides high-speed internet up to 150Mbps for remote video streaming, ROS (Robot Operating System) node communication, and cloud telemetry.
GNSS Positioning: Built-in support for GPS, BeiDou, and GLONASS ensures you get accurate, real-time location tracking for autonomous navigation.
Power Requirements: Operates nominally at 3.3V logic, but requires a robust 5V power source that can supply peak currents up to 2A during cellular network handshakes.

Questions
How big is the Trackimal PCB?
It measures 40 × 52.2 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Trackimal use?
95 parts, built around the SIM7600E, AMS1117-3.3, MIC29302WU and ACPDUC24V-HF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Trackimal KiCad files?
From the Vtechcode/stm32f303_sim7600 repository on GitHub, at the commit this page was made from: the board is trackimal.kicad_pcb and its schematic trackimal.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Trackimal design in my own project?
Its repository states no licence, so its author keeps all rights: ask Vtechcode before reusing the design.
