SD/MMC Socket for Secure Digital Disk or Multi Media Cards

sku: PRT-00136

Description: Do you need a lot of space? EEPROMs not quite enough? How's 1GB sound? This is a socket used to interface to SD (Secure Data Disk) and MMC (Multi Media Card). We used it to test out our 'PIC to FAT16 on SD' routines. The SD/MMC cards use a very simple SPI serial bus as well as a 4-bit proprietary bus.

A breakout board is available below.
