PCB component replacement and firmware redevelopment.

Good day, I have more than 30 years experience in PCB, Arduino and ESP designing. I can develop embedded Hardware and software while meeting your requirements. I would like to have a thorough discussion on this project as there are certain suggestions from my side After dedicating more than 30 years to the electronics design and development, I am passionate in designing the best products Technology wise I have worked on all the latest technologies like GSM, 5G, Lora etc. And have worked on more than 20 design tools for designing and simulation purpose Some of the generic queries from my side are: 1. What is the application of this product? 2. What will be the ambient temperature of this product? 3. What are the mechanical constraints to be taken care of? If you are someone who wants to benefit from my experience just message me Hi and I shall be there for you Regards Hari Mohan Engineering for one is magic for others

Hi, Greetings...! I am interested to work on your project. Please share the hardware details and let me know which components need to be replaced. Looking forward to working with you. Thank you Shivkant
