Modify esp32 sensor for new version
Budget: $30 – $250 USD
The new one I am looking to do I also want as small as possible but this time a rectangle as skinny as possible. This one should still have the i2c JST port and USP C charging/ flash port. No need for the LUX, Temp , TOF sensor or the JST 5v power. Want to add the ability for battery that can be charged from usb c port and want 4 ports for analog wire check.
Charging needs to have battery protection.
Using these external sensors want be Able to do 4 seat sensors and have 3-4 months battery life. Should be able to deep sleep most time unless state change.
Looking to make this as skinny and small as possible as it would go in a couch under the cushion.

Here is an example config

If you could estate battery size needed but it should not be too large. Maybe could do small connector to add battery or a standard external one .
So to summarize I am looking for a esp32 based board that can be powered with battery and/or usb c ( should work without battery) , reset, i2c JST port and 4 wire connectors for sensors.
How much for you to make this version of the board?
