Experience of using EasyEDA to develop training boards on the PIC16f887 microcontroller

Abstract

A brief overview of computer-aided design (CAD) systems widely used in Russia is presented, and the main requirements for tracing PCB boards are given. The main features of the actively developing cloud CAD system EasyEDA are shown, and the expediency of its use is justified. The idea of creating low-cost electronic training boards based on the PIC16F887 microcontroller for studying the basics of microprocessor technology is presented. Electronic training boards demonstrate all the capabilities of the microcontroller - the operation of the I/O ports, serial port, analog-to-digital converter(ADC), with a two-line liquid crystal display (LCD), with temperature sensors, with a DC motor, with a stepper motor, etc. The experience of developing a budget electronic training boards based on a PIC microcontroller in EasyEDA, which can be used to study the programming of microcontrollers, is shown. Shown are the possibilities of using the jlcpcb.com service to order PCB boards in the largest PCB prototyping enterprise in China, called JLCPCB.
