Although not really necessary, layering various "breakout boards" onto PCB foundations that use electrical traces to connect various parts will definitely cut down on the mish-mash of wiring that would otherwise be required. I have settled on a configuration providing 16 each of analog, serial, and I2C sensors. This is way more than I ever anticipate needing however it does offer plenty of room for expansion and doesn't cost much more than limiting to 4 or 8 sensors...so why not go for it.</span></div><div id="m_-2601216684549208027yui_3_16_0_1_1527120823372_3083" dir="ltr"><span><br></span></div><div id="m_-2601216684549208027yui_3_16_0_1_1527120823372_3083" dir="ltr"><span id="m_-2601216684549208027yui_3_16_0_1_1527120823372_3557">I am using ExpressPCB for the PCB design work.
