Hi there. I have just read your requirements in detail and became interested in this project. -https://www.freelancer.com/projects/pcb-layout/PCB-Adjustments/reviews As you can see my review, my specific skills are electronics and electrical engineering. I developed a digital relay protection device by relay using microcontroller and I tried to communicate between device -HMI , device-PLC and device-PC. I've tried manipulating Wireless communication by Zigbee and RF, Rs485 communication, 232 communication, and USB communication according to the MODBUS communication protocol and LCD control, SCR control and IGBT control, etc, with Microcontroller, Arduino and Raspberry Pi, etc. I use programs such as Altium Designer, Proteus, mikroC PRO, Pic c, Mplab, HI-TECH, Keil, python and Qt etc. I’m also full stack web developer. I am confident I will be able to carry out this project and I am ready for your test at any time. So, I hope we will discuss more details about your project through chat. Then, I'll do my best for you and I'll give you the best results within the specified deadline. I am a person who puts credit first. Looking forward for your response. Best Regards.
