Getting To Blinky Getting to Blinky 4.0 is a short video series introducing the key concepts of using the open source ecad software KiCad. You will be building a small blinking board to cover each of these concepts. CE Header The “CE Header” is a generic header that makes any development board or breakout board into an instantly “connected” device. It is a simple abstraction of offerings that most small microcontroller development platforms have, such as the Arduino or the BeagleBoneBlack. In cases where there is not a requisite feature, add-on logic will be added to make it compatible. Power Swap The power swap module is a range of videos about choosing switching regulators for converting from one voltage to another. There are some advanced topics around inductors, capacitors and mosfets. Current Sink Or Swim This category is for the CSOS project, which was originally part of CE v2.0. It's a standalone current sink, including descriptions on how to design and construct the board.
