Features:
- OpenLog open source data logger
- Supports microSD cards up to 32GB
- Can log serial data on a serial bus to store all the serial data that your project generates
- Useful for scientific or debugging purposes.
- Uses an ATmega328 running at 16MHz
- Draws approximately 2-3mA in idle (nothing to record) mode
- During a full record OpenLog can draw 10 to 20mA depending on the microSD card being used.
- All data logged by the OpenLog is stored on the microSD card.
- Any 512MB to 32GB microSD card should work.
- OpenLog supports both FAT16 and FAT32 SD formats.
Specifications:
- Power Supply Voltage: 3.3V-12V (Recommended 3.3V-5V)
- Simple command interface
- Configurable baud rates (up to 115200bps)
- Preprogrammed ATmega328 and bootloader
- Four SPI pogo pins
- Two LEDs indicate writing status
- Current: 2mA idle, 6mA at maximum recording rate
- Logic Level: 3.3V / 5V
- Supports Micro SD cards and Micro SDHC high-speed FAT16/32 cards up to 32GB
- Communication Protocol: SPI and FTDI (SPI for reprogramming the Atmega328 bootloader and FTDI for data transmission)
- Primary interface: FTDI that can be connected directly to an Arduino to send data over a serial connection to the OpenLog
- Micro SD card port on board
- RXI Input: 2.0V-3.8V
- TXO Output: 3.3V
- 2 Status LEDs:
- Right LED: Indicator LED toggles on/off when a new character is received. This LED blinks when Serial communication is functioning.
- Left LED - LED blinks when the SPI interface for loading the Atmega382 bootloader is active. You will see it flash when the OpenLog records 512 bytes to the microSD card.
- Pinout:
- BLK: Ground 0V
- GND: Ground 0V
- VCC: 3.3V-12V (Recommended 3.3V-5V)
- TXO: Transmit Output
- RXI: Receive Input
- GRN: Data Reset
- How to connect to FTDI Basic: (See diagram in images)
- OpenLog BLK → FTDI Basic GND
- OpenLog GND → FTDI Basic GND
- OpenLog VCC → FTDI Basic 3.3V
- OpenLog TXO → FTDI Basic RXI
- OpenLog RXI → FTDI Basic TXO
- OpenLog GRN → FTDI Basic DTR
