The Adafruit MicroSD card breakout board will let your next project store up to 2Gbytes of data using just 4 x pins on your microcontroller. Its onboard 5V to 3V regulator means it can supply up to 150mA to demanding SD cards. The board is 3 or 5V compatible and the level shifting has been done with a chip which makes it more reliable and allows faster read/write access. Adafruit have a free tutorial on all things micro-SD.

Supplied as a fully assembled board plus a 1 x 8-pin 0.1in. pitch male header strip for you to solder in as required.

I have two of these and have managed to get both of them working using elm chan's FatFs and also petite FS code. One (FatFs) reads CAN data from my Aston dsPIC30F4013 (with a real time SPI clock), and the other petitFS is on a pic16f876 which has only 2000h characters of program space, and reads gravity from a GY291 board (SPI) and writes data to files. I did have to implement an OR gate on the card reader clock input to make it ignore traffic from the gy291 to the pic on the petitFS project as the card seemed to ignore the CS input
