This tiny circuit records all GPS coordinates into the microSD card from your ordinary OSD. It's compatible with all GPS and OSD brands.

ArduLog is a stamp size circuit which has the capability of doing RS232, I2C and Analog logging.

It's including a microSD socket, 2 color led for status and 4 input pin that connected with 6 ports of Atmega328 processor.

Current firmware records the GPS positions from directly any GPS embedded device. It is supporting all GPS models which have standard GPGGA NMEA protocol.

The Baudrate of ArduLog is configurable with putting the _BAUD.TXT file into the root folder of microSD card. We tested it with all rates between 4800-115200baud.

Just create a file that named _BAUD.TXT and type the baudrate into. (like 115200)

ArduLog reads the file on startup and logs the GPGGA sentence of GPS data. Then our free KMZ generator software generates flight path KMZ files for Google Earth.
