Description: This is a ready to go module that utilizes the DOSonCHIP FAT16/32 IC with accompanying SD socket. Excellent evaluation board for the DOSonCHIP silicon or for simple datalogging and file storage! Uses a simple UART or SPI interface. Datalogging is now as easy as sending ‘md CHAT’ to make a directory! Low 5mA current consumption.

If hardware flow control is not needed, tie CTS to ground.

SD card sold separately below.
