I need 3 schematics (eagle files) based on Arduino Lilypad 328 as base. The original design is published in: [login to view URL] [login to view URL] They must be considered at first design and I need some modifications. The 3 designs are: CIRCUIT 1. Maintein ONLY the following 9 pins (the other 11 pins are deleted from the board and the board will be smaller): - VCC (+) - GND (-) - 0/RX - 1/TX - 2 (DIGITAL IN/OUT PIN). It doesn't matter if it is the #2 PIN or other (can optimice design if choosing another digital pin is better). - 3 (DIGITAL IN/OUT PIN). It doesn't matter if it is the #2 PIN or other (can optimice design if choosing another digital pin is better). - A0 (ANALOG IN/OUT PIN). It doesn't matter if it is the #A0 PIN or other (can optimice design if choosing another analog pin is better). - A1 (ANALOG IN/OUT PIN). This pin has to be connected to GND through a 10K resistor. It doesn't matter if it is the #A1 PIN or other (can optimice design if choosing another analog pin is better). - A2 (ANALOG IN/OUT PIN). This pin has to be connected to GND through a 4.7K resistor. It doesn't matter if it is the #A2 PIN or other (can optimice design if choosing another analog pin is better). The oscillator, the Atmel ATtmega328 microcontroller with the arduino boot inside, the reset button... and more components originally contained in Arduino Lilypad 328 must be maintained as usua (they don't change). As you can see, the changes I need are basically delete several pins from the board, add 2 resistors between 2 analog pins and GND, and reduce the size to the minimum (less pins, so the circle is smaller). CIRCUIT 2: Take the CIRCUIT 1 as base and add in the same side a ADXL330, adding also the necesary pins that were deleted from the original circuit. CIRCUIT 3: Take the CIRCUIT 2 and and a CC2540 on the other side. ---------- As you can see, the CIRCUIT 1 is well defined, but the CIRCUITS 2 and 3 need more work to get the optimun design.
