You will get firmware for Arduino, ESP32 and Raspberry Pi4,5
Top Rated
Project details
You will the firmware, PCB design & Mobile App for your electronics prototype.
I have access to the electronics lab so I already have most of the components and modules so I will setup the test environment at my end to make sure code is tested before delivery.

If you're unsure which components or architecture are best for your project, I can help you select the right hardware and software before development begins.
Most of my Upwork projects are covered by NDAs, so many of the products I have developed cannot be shared publicly. However, I am happy to discuss my experience, development approach, and how I can help bring your idea to life.
