Change the RGB LED #1

Closed ntosis closed 8 years ago

ntosis commented 8 years ago

Change the component for the RGB LED to the 150141M173100 from Wuerth Electronics and add three resistors for every LED. The old component is obsolete and only one resistor for three LED are wrong.

The files unter the Brunch "Arduino" PhaethonBrdArduino/PhaetonArduinoBrd.sch and PhaethonBrdArduino/PhaetonArduinoBrd.brd will be affected.

The resistors are calculated due to datasheet from Wuerth electonics. Blue=16mA Red=13mA Green=3mA for the same cmd value. Rb=5-3/0.016=125 Ohm, Rr = 5-2/0.013 = 230 Ohm, Rg = 5-2.7/0.03=90 Ohm

The changes are committed.

wrong calculation for Green LED , Rg = 5-2.7/0.03=90 Ohm => correction Rg = 5-2.7/0.003=767 Ohm. Update the value of the resistor in Eagle file.
