Dear Sir,
I am an highly skilled board designer who has over 17 years experience on complex PCB design. I can provide you design service from schematics entry to PCB layout. I can also provide the prototype service. I can provide lora PCB, gerber. But I can not provide firmware.
Please message me if you are interested. We can talk more.
EDA tools: ALTIUM17/ORCAD16.6/PADS9.5/EAGLE
Thank you!
