SparkFun Single Board Computers SparkFun OpenLog Editorial Review
The SparkFun OpenLog Open-source data logger is a compact and reliable tool for serial data logging. With a simple serial connection, it supports microSD FAT16/32 cards up to 32GB and configurable baud rates up to 115200bps. The device comes preprogrammed with ATmega328 and bootloader. Customer feedback for the SparkFun OpenLog is generally positive. Users have found it to be a useful tool for various applications, such as measuring the debugging interface of a product and logging debug output of devices in the field. The device is easy to set up and comes with helpful documentation and labeled pins. However, there are some areas for improvement. The durability of the SD card socket has been a concern for some users, with reports of it breaking after a few insertions. Another user mentioned that the device struggles to keep up with a steady 115200 baud stream, which could be due to the SD card speed. It would also be beneficial for the device to have a clock/cal to timestamp logs and the ability to run faster than 9600 baud without data loss. Overall, the SparkFun OpenLog Open-source data logger provides a compact and reliable solution for serial data logging, with the only downside being issues with durability and high-speed data logging.
