Subject: Inquiry for Prototype and Production of Medical Smartwatch Module with LoRa Communication

Dear [Manufacturer's Name],

I hope you are doing well.

I am developing a medical smartwatch and would like to inquire about the production of a custom module that integrates various sensors and hardware components. A key feature of the smartwatch is the integration of a LoRa transmitter to enable communication between individual smartwatches.

My plan is to first develop a working prototype, after which I would place an order for 10 prototypes. If successful, I would then proceed with a bulk order for trading purposes.

Please let me know if you are able to assist with this project. For more detailed information on the complete working of the smartwatch, feel free to contact me directly.

Thank you for your time, and I look forward to your response.
