For the second board, we can start with the first.
-We can remove all of the external power (12-14v) and power these components from the Arduino 5v (it might be smart to power the sensors from the 5v pins next to D22/23)
-Keep the 5 screw terminals for the ds18b20 sensors
-Keep 2 thermistor terminals (2 screws)
-Keep 2 of the 5v-Gnd-Data sensors (6 screws total)
-Keep 2 interrupts (2 screws)
-Keep 2 voltage dividers
-Keep 1 extra 5v and 1 extra Gnd screw terminals
-19 total screw terminals all to be placed on the Power/Analog side of the Arduino Shield
-Keep all of the connections for the Neo-6m, LSM303, and 2x HC-05 chips as they are wired in PCM1.
-Add a header for a 20x4 LCD connection. (image attached- I am using this wiring)
-Add three buttons that will trigger page changes and other inputs on the LCD (5v, Gnd, and connect each to any unused Data pin through resistors)
-Add a 5k potentiometer in the LCD wiring as shown above

Hi. Am a Mechatronics engineer with experience in sensory circuitry, and PCB circuit layout and Arduino programming. PCB Design by Eagle or Proteus. Looking forward to working with you. Thanks
I have experience in the design of pcb and production of them, over time I have designed several development cards for pic and I am interested in this card based on arduino
