Learning Eagle CAD

If you need a refresher for Eagle CAD training this was your assignment in BME 210. Each of the 4 modules will take you about 1-2 hours where as each of the parts of a module is about 20-30 minutes. The actual design of the barebone board takes about 3-9 hours.

Design Practice

As design practice you can design a barebone Arduino board as shown here: https://cdn.sparkfun.com/assets/6/e/4/f/4/52127868757b7f30438b4567.pdf.

The steps to create the barebone is illustrated here https://learn.sparkfun.com/tutorials/using-eagle-board-layout

You would need the following parts:

• 5.5mm Barrel Jack (PTH) SparkFun-Connectors, POWER_JACKPTH

• 0.1µF Ceramic Capacitor SparkFun-Capacitors, CAPPTH

• ATmega328P (PTH) SparkFun-DigitalIC, ATMEGA328P_PDIP

• ¼W Resistors SparkFun-Resistors RESISTORPTH-1/4W

• 5mm LEDs, SparkFun-LED, LED5MM

• 0.1µF Ceramic Capacitor, SparkFun-Capacitors, CAPPTH

• Voltage Supply Symbol, SparkFun-Aesthetics, VCC

• Ground Symbol, SparkFun-Aesthetics, GND

• 8-Pin 0.1" Header, SparkFun-Connectors, M081X08

• 2x3 AVR Programming Header, SparkFun-Connectors, AVR_SPI_PRG_6PTH

• 6-Pin Serial Programming eader, SparkFun-Connectors, ARDUINO_SERIAL_PROGRAMPTH
