Added README

Version 2
Changed inductor footprint to match actual inductor size (oops) Changed bootstrap loop components to 0402 to reduce ESL Removed a somewhat pointless input cap Moved output filter caps closer to output Adjusted schematic to have more realistic voltage ratings Changed output ceramic capacitors to 50V 10uF 1206's (cheaper and less ripple) Thermal relief spokes on THT components Rearranged some things Reduced board size by 1mm Made some aesthetic improvements Added maximum current rating, board version and license to silkscreen Board now conforms better to IPC-2221 (particularly conductor spacing)

Author	SHA1	Message	Date
Logan G	f667df3f17	Added README	2023-02-18 23:22:31 -07:00
Logan G	9c1795d1f4	Version 2 Changed inductor footprint to match actual inductor size (oops) Changed bootstrap loop components to 0402 to reduce ESL Removed a somewhat pointless input cap Moved output filter caps closer to output Adjusted schematic to have more realistic voltage ratings Changed output ceramic capacitors to 50V 10uF 1206's (cheaper and less ripple) Thermal relief spokes on THT components Rearranged some things Reduced board size by 1mm Made some aesthetic improvements Added maximum current rating, board version and license to silkscreen Board now conforms better to IPC-2221 (particularly conductor spacing)	2023-02-18 04:55:30 -07:00
Logan G	ee7a439ea3	Actually updated LCSC part number, oops	2023-01-19 12:51:38 -07:00
Logan G	537e0aa509	Fixed LCSC part number for EN screw terminal	2023-01-19 12:48:36 -07:00
Logan G	7b8be7caa5	Added screw terminal and solder pad for EN	2023-01-05 22:44:35 -07:00
Logan G	35bfcacf42	Centered back silkscreen text (very important!!!!!!!!!!!!!!!!!)	2023-01-05 19:54:41 -07:00
Logan G	3a9c7be044	Reduced board size	2023-01-05 19:34:39 -07:00
Logan G	551a96fca9	Finished draft of PCB	2023-01-04 20:46:29 -07:00
Logan G	16887febc0	Fixed gitignore	2023-01-04 20:46:12 -07:00
