looking for a dc to dc power supply and how do I know the max current?
For my project, I require 3.3 V (for the P1 and segment LEDs) and 5V for Pixel LEDs in the same package.
I think I need a 12V DC to DC converter with 2 outputs (3.3 and 5V DC). I think 4-5 Amps are needed but not completely sure.
I'm looking for something similar to Parallax part 32133. Ideally the converter would have a 2.1mm input jack and output both 3.3 and 5V. The size would be small. I'm making an LED a wall clock. Is this what I should be using OR should I be using something else? Should I build a similar circuit that is on the Propeller Professional Development Board (32111)?
Can someone help me figure out what the max current is?
1x50 piece pixel lights that come with Parallax part 64030. Label says 5Vdc/0.3W. I'm assuming that means per pixel.
10 x KWA-541CPGB LED segments.
1x RTC DS233 that comes with Parallax kit 64030.
1xP1 at 80MHz
