PCB a Week 19: SD Card Breakout for breadboards

SDbb1

Mats continues his challenge of designing one PCB every week.  In week 19  he came up with breakout board for micro SD cards:

This weeks PAW is just a breakout board for micro SD cards. There’s a number of boards like this on the market already, but they are kinda expensive and I like doing my own stuff, so here it is… :-)
The board have a LDO that supplies the SD card with 3.3 volts and there are proper level shifters on the board so it can connect to 5 volt devices. I’ve added a LED that will light up whenever a card is inserted and it will also double as a power indicator.
