特徴

• SDLogger is a simple serial logger based on SparkFun/Nathan Seidle's OpenLog. It is using an ATmega644P processor running at 14.7456MHz and logs to full-size SD cards. It supports both standard SD cards（FAT16）and SDHC cards（FAT32）. SDLogger ships with OpenLog firmware 1.61 installed（compiled with SDHC/FAT32 support and large 2048 character input buffer）together with an Arduino-compatible bootloader for easy program update.
• Features
• Simple to configure and use
• Automatically logs data received on the serial input port
• Can be configured using a config file on the SD card
• Supports 2400、4800、9600、19200、38400、57600、115200 and 230400 serial baud rates at 8-N-1.
• Supports both standard SD cards up to 2GB（FAT16）and SDHC cards up to 16GB（FAT32）
• Large input buffer（2048 characters）
• Full-size SD card form factor
• 14.7456 MHz crystal oscillator for precise baud rate generation
• Input voltage range：3.3 to 12V
• Arduino-compatible bootloader installed for easy program update
• Full Arduino environment support - can be used as an inexpensive Arduino board for program development
• I/O ports supported in Arduino environment（in addition to the main serial port）：4 analog inputs、second serial port、I2C port
