HC32 Extended Version

Overview

This design is based on an expansion board developed using the HC32F4A0PITB-Youth Edition. Its functions include reading satellite time and location information via a GPS module and reading temperature and humidity via an AHT20 sensor, displayed on an OLED screen. Future updates will include displaying current speed based on satellite positioning. It can be placed at home to monitor indoor temperature and humidity as well as a clock, or in a car to display vehicle speed and interior temperature and humidity.
