Description
The device is used to write data directly tothe microSD card andcommunicatesthrough a simple serial interface (RX and TX outputs). The module supports cards up to 32 GB with FAT16 and FAT32 file system.
The set includes a2.54 mm goldpin raster connector, whichcan be soldered separately.
Support
The device should be connected through the serial interface UART - RX and TX outputs. After the power supply is switched on and data is transmitted, OpenLog will start writing them onthe card.Default transmission speed is9600 bps. In order to enter configuration mode, a sequence of three timesctrl+z,command ."newcreates a new file,"md"newcatalogue. Configuration fileconfig.txt,whichis located on the memory card can be edited from the computer. This allows you to easily select the operating mode and set the transmission speed.
The use of the layout is facilitated by asample program forArduino anda list ofavailable commands. Module users can also use the prepared tutorial.Description and sample programs can also be found on GitHub website.
