1  140-XRL16V1000-RC     1000 uF, 16V Radial-Lead Elect. Cap         C1

The on-board regulator should only be used if measures are taken to keep the current consumption down (omitting the on-board LEDs, and using the non-PWM firmware). If the LEDs are used and the PWM firmware is installed, the current consumption if the board is about 1A, and so the regulator will dissipate too much power (the small value of C1 precludes decreasing the input voltage).

Revision History

 7/21/2007 BOM copied from picdimmer forum, on-board regulator made optional
 7/21/2007 Value of regulator parts (diode, regulator, cap) changed.
 7/21/2007 Value of LED current limit resistors changed.

Errata for Rev XA PCB -

 1) The trace between J4 and D1 is too small, and needs to be beefed up if the board is configured to draw more than 1/2A through J4.
 2) There are two diodes labelled D4.
 3) The holes for D1 are too small.
 4) The silkscreen reference designator for C3 (above U10) is missing.
