    Hello, I am a electronics and embedded systems engineer with experience in the field for more than 7 years. I have worked with many clients for various projects for layout designing and circuit designing for motor drivers, iOT devices, development boards and many other custom requirements. I design the circuits in Altium Designer which is a top software for the task. Also I can offer full turnkey solutions. If you have a certain requirement I can offer my service as follows. 1. I can design the schematic and design the board layout and provide you manufacturing files. Then you can contact a manufacturer and get them manufactured. 2. If you are engaged in a more continuous development project or a prototyping project I can design the circuit, design they layout, source and order the components, solder them, test the circuit and send you the prototype as a final product. You can then review it's performance and consider to add more features or development if you wish. Other than that if your design requires a certain part of firmware writing I can arrange that for you too. Also I have a team of engineers who are developing web apps, mobile apps for hardware and iOT projects. Embedded system development boards and platforms Weather monitoring systems GPS tracking and reporting Vehicle tracking Live emission testing Safety systems Motor drivers Internet of things applications Measuring equipment Biomedical equipment STM32 based boards Arduino compatible boards I provide you a very detailed documentation for the project: The source files including the Altium Schematic file and PCB file with libraries The Gerber Files with NC Drills BOM- Bill of materials PnP- Pick and Place file for assembling the PCB 3D model of the PCB in .step format 3D pdf file of the PCB Assembly drawing Design Verification Report Thank you for contacting me. Lets pursue a great journey together.
