hello sir. I have just read your job description and your project is really interesting to me.
The Items you raised are similar to what I have already done in practice and I think you can do it in a short time if you have a little explanation.
I'm an expert having specialization in Electronic Engineering Design.
✔️ Embedded system based on Microcontroller (ATMEGA, AVR, STM8, STM32, MSP430, TMS320, PIC ...)
✔️ A system based on development boards(Arduino, Raspberry PI, Node MCU, Bluechip, Teensy,…)
✔️ Antenna design & Analog circuit/RF communication circuit designing and simulation using Proteus, P-Spice, Tina Pro, ADS, CST, Ansys, HFSS
✔️ Bluetooth, WIFI, zigbee, LoRA
✔️ High-Speed layout using HyperLynx
✔️ PCB layout designing, providing GERBER and BOMs, 3D files using Altium, EAGLE, Kicad, EasyEDA…
✔️ Programming firmware of Microcontroller & C++
✔️ BMS
I think my many design and practical experiences can help you design your project and give you enough satisfaction.
I look forward to your response.
Best Regards.
