ThermovitalSync-PCB

A PCB project with KiCad 8.0 for a vital monitoring and cooling device with GUI

Key features

• Compact 4-Layer detachable microcontroller PCB with 12V,5V,3.3V power rails from a 11.1 V Lipo battery
• Pulse, ambient and internal body temperature sensors
• Peltier and fan modules to implement cooling or heating for the user
• Microphone and Speaker components to implement voice activated switches.
• GUI with TFT LCD touchscreen using MicroPython
• 6x7 cm compact design

Rev 1.

My first Microcontroller board had its essential pins rx and tx reversed and some other small issues in the layout section so there was a revision of the ucontroller board.The last version of the board.

Manufacturing with PCBWay

Since PCBWay reached out to sponsor my project and help manufacture the boards, I have accepted their kindness then sent my gerber and nc drill files to their website. Thanks to Liam from the marketing department and the helpful customer service workers of PCBWay, I was able to coordinate and order the PCBs with ease and receive them in just 1-2 weeks!

My review of their manufacturing experience is included in the Assembly section

Assembly

Thanks to PCBWay's sponsorship, I was able get my boards manufactured quickly and with high reliablity from a professional pcb manufacturer. All 10 delivered boards seemed identical without any flaw or defect on them. After hand soldering the BOM, with some calibration, All the boards and their integrated combination worked flawlessly. Thus making the boards fully functional.

Here are the two assembled PCBs attached together to give the final project life.

Although the hardware part of the project is done, there needs to be embedded software written for the chip to maximize its usage(sd card, joystick and peltier function). Coming soon...
