The BOM and schematic are provided at the bottom of this page.
This module was designed as I spent eight years in the power semiconductor business unit of a large multinational company and felt embarrassed to use modular power supplies. One problem with this embarrassment though, commercial DC-DC modules are really-really cheap. So, use this module if you are planning to go into very high production volumes and want to test with the eventual power supply you'll design in. Otherwise just get a fully test / cheap module off DigiKey.
