ALFAT SD board is an OEM board uses ALFAT™
SoC processor. This board offers a seamless way
to access files on SD, SDHC and MMC cards with
ALFAT SoC processor. The board include a
standard SD/MMC connecter that includes a push
spring.
The board includes pads for RTC 32.768Khz
crystal but the crystal is not included.
All required signals are exposed through a 1x16
pin-mount. Also, if the desired interface is UART,
all signals required are exposed through a
secondary 2x5 pin-mount.
