Dear Sir,
I'm Professional Hardware and Firmware Engineer. I have developed several IoT before so I know several Issue related to hardware design(Antenna design, Power supply design, Component Placement, etc). I have experience in designing various IoT board with Cellular Based, Wifi Based, Bluetooth based, and general practical design for it. I know how to manage power over IoT board including charging IC design. I also know how to choose component related for certain application, as I have experience on Military grade Electronics development. In Firmware, I always use Arduino based environtment, because we can easily find Sensor library for it. So, it can faster development process.
Generally, I have designed a lot of project for various application, from hobbyst, Robotic, Industrial, IoT, Audio, also for Military application. I have experience designing multilayer board, as well as advanced PCB circuit like High speed digital communication, differential pair, Buck, Bost DC-DC converter, Battery management systems, Mixed signal, Isoalted I/O, BGA fan out, etc.
I'm familiar with both 8 bit or 32 bit Microcontroller family. My knowledge including AVR, STM32, NXP, ESP,NRF. I'm open to learn another microcontroller if neccessary.
In PCB design I can use EAGLE, KICAD, and Altium, although most of my project were using EAGLE and KICAD.
Lets discuss the detail over chat.
Best Regards,
Rijal
