I have a project using DS18B20 temperature sensors and water flow meter.

My prototype is based on M5 core2 and is working fine.

Now I plan to commercialize a product based on that prototype.

I want the users to get a plug and play device, so I want to sell them the core + cables + sensors, easy to plug and start.

I think I do not need to produce a specific board to stack on core, because the sensors only needs a pullup resistor.

May be that resistor can be integrated into the sensors cable (on the connector) ?

What is your opinion on this point?

I was thinking of making a cable that plugs into the M5core1 (basic), on the side GPIO connectors. Because Core2 only have bottom connector.

Do you think it will be easy to mass-produce this type of cable in the future ?

Thanks for your help
