# Fifth Lichuang Electronic Design Competition# Programmable DC power supply based on GD32F303RCT6

Overview

1. Self/Team Introduction: I have been engaged in the automotive automation industry for many years. Familiar with ST, NXP, GD series microcontrollers, digital and analog circuits. 2. Briefly introduce the project: Using the GD32F303RCT6 chip as the main control, design a DC adjustable power supply with adjustable voltage and current. The power input is an ordinary power frequency 24V transformer. The UI interface is a 7-inch configuration screen (optional). The upper and lower layers interact through the MODBUS protocol. The UI interface displays current voltage, current, working mode and other parameters. And the onboard 4-digit digital tube displays current and the 4-digit digital tube displays voltage.

* 7. Whether it is published to the public for the first time. It is the first creation and has not been published on other websites.
