Hi,
I have worked on many Arduino and Raspberry pi, ARM Microcontroller, PCB designing Projects.
I can also send to you the list of my project.
I can design the PCB in all layers like multiple, double and single layer.
I can provide you program (source codes) and PCB designs as per your requirement.
The actual cost of project depends on details, here i just set the place holder value.
Please send me more details of project.
Thanks,
Chanchal k.
