This is a ready to go module that utilizes the DOSonCHIP FAT16/32 IC with accompanying micro-SD socket. Excellent evaluation board for the DOSonCHIP™ silicon or for file storage, simple datalogging, and high speed API datalogging! Uses a simple UART or SPI interface. Low 5mA current consumption.
DOSonCHIP is very powerful and supports larger SD cards (up to 32GB) but requires a more complex command structure. For simple data logging, we recommed OpenLog for beginners.
The DOSonCHIP embedded file system and SDHC/SD/MMC controller makes it easy to add up to 32GB of storage to your project without adding software complexity (OS Not Required). Add flash storage for data logging, configuration, audio recording, web serving, and more with this high speed, low power IC. DOSonCHIP is a drop-in solution with UART and SPI interfaces and included host-side ANSI C code—just fill in the appropriate definitions for your host communications port (or leverage the included bit-banged SPI code). The open source interface code provides comprehensive file system access functions that will be familiar to any C programmer. Commented sample code that demonstrates how to use all of the functionality of the DOSonCHIP is provided too. Adding high-capacity removable storage to an embedded project couldn’t be easier!
We now have ICs with v2 firmware. Compatible with SDHC (up to 32GB!) and 60 times the speed of the original version.
If hardware flow control is not needed, tie CTS to ground.
