#The 8th Lichuang Electronic Competition# [Lichuang Electronic Competition] Desktop electronic clock based on Renesas

Overview

Project introduction:
Replica of the 2023 Jialichuang Renesas training camp desktop electronic clock.
[1] The main control is Renesas R7FA2E1DFL, Cortex-M23 core
[2] Use Jialichuang EDA Professional Edition to draw a two-layer PCB
[3] 4 digital tubes display time, temperature, and humidity information
[4] The temperature and humidity sensor is DHT11
[5] 4 buttons are used to set the time, and the touch area pads on the circuit board are used to switch information display
[6] 1 manual reset button, 1 BOOT button
[7] Use a PMOS and a diode to form a power switching circuit, which can be powered by USB or lithium battery, and the charging management chip is TP3401
[8] Lead out 1 serial port and SWD
Thanks to Jialichuang and Renesas.
