README

GPS PND Project

This repository contains the KiCad design files and documentation for the GPS PND (Portable Navigation Device) project. The design includes a power supply circuit, STM32F301K6 microcontroller, and the MS38SN4 GNSS module, aimed at providing GPS functionality for various IoT and navigation applications.

Features

Power Supply: AZ1117-3.3

• Stable 3.3V output for powering the MCU and GNSS module.
• Low dropout regulator with thermal shutdown and overcurrent protection.
• More Information - AZ1117-3.3

Microcontroller: STM32F301K6

• ARM Cortex-M4 operating at 72 MHz with FPU for enhanced processing.
• 32 KB Flash memory and 16 KB SRAM.
