However, I was able to finish the electrical schematic for Rev 2.1, which you can see below. The circuit will be much simpler than the previous iteration as I was able to eliminate\u00a0many components with this new design. Below are the changes.<\/p>\n<ol>\n<li>No need to boost the voltage so I got rid of the voltage regulator chip and the accompanying circuitry<\/li>\n<li>Transistor configuration into a single FET array chip -http:\/\/www.diodes.com\/datasheets\/DMHC3025LSD.pdf<\/li>\n<li>Smaller Lithium battery will be used, haven&#8217;t decided on the form, but am looking at lithium coin cells<\/li>\n<li>Different battery charging management\u00a0IC \u00a0http:\/\/ww1.microchip.com\/downloads\/en\/DeviceDoc\/22036b.pdf<\/li>\n<li>Atmel chip microprocessor will be used instead of the whole Sparkfun Pro Micro (have not implemented in schematic yet)<\/li>\n<li>Battery monitor IC to indicate when battery is low<\/li>\n<\/ol>\n<p>Note: This is only the first draft.
