Dear Sir,
I am an expert with more than 20 years of experience in embedded systems, electronics, prototyping and PCB Layouts. I have worked alot on automation and embedded systems projects in the past based on LoRa, RF, WiFi and BLE.
I have checked the details of your work. I will prepare x2 working prototypes in this budget. I am online and available for discussion.
Regards
Talha
