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

Fritz the Cat” Hi, Hope you are doing well. I am interested in this PCB design project. I have experience with Altium, Eagle, KiCAD, and EasyEDA software tools. I have completed several PCB layouts based on microcontroller, Power supply, SMPS, DC-DC converter, RF, and impedance-matching PCB layouts. I have great control over impedance calculation for RF PCB design. I have expertise in interfaces like SPI, I2C, UART, USB, RS485, and CAN. Furthermore, I have a good grab on Firmware development for ESP32, Atmel, Microchip, STM32, Raspberry PI, nRF51 & 52 microcontrollers. What you will get from me; Source Files(Schemtich, PCB layout, PDF, and DRC File) Manufacturing files(Gerber FIles+NC Drill FIles+Pick and Place+Bill of materials(BOM)) Why choose me; PCB layout always maintains the standard manufacturing rules After completing the PCB layout, all the designs will go for several times electrical rule checking. And, I always try to make it 100% error-free. I will provide the manufacturer standard PCB files, such as JLCPCB, PCBway, nextPCB, Colorado PCB, PCBhero, etc. Regards, Raseduzzaman Ruman Sr. Embedded System Engineer
