Power Regulator Modification

12-31-2010, 04:45 AM Code 4-80 Power Regulator Modification
This modification to the LM1086 CS-3.3 is now completed on all 20 Parallax Propeller Proto Boards.

 
The mod involves desoldering the voltage regulator's middle leg to disable all circuits behind the device.

Power is fed to all boards from an external power source. This reduces power consumption by disabling the power LED and two regulators.

This disables the power LED, however, the small modification described in the previous posts enables it to be recycled and function as a data light.
