DEVMO Openlog Serial Data Logger Open Source Data Recorder ATmega328 Support Micro SD Module

This product is a data logger that records data on a memory card via the uart universal serial port. This function resembles a black box to record the data sent to the serial device by the master device and save the data in memory on the memory card. This product can be used with cleanflight firmware with the control board, connected to the corresponding serial port, through the host computer software cleanflight configurator settings, can be realized on the UAV's important operating data recorded on the memory card. And flight records are analyzed by Blackbox flight data recorder software.Note: After inserting the memory card for the first time, the memory card will produce the config.txt file, which changes the baud rate parameter of the serial port. This parameter can be modified. Please set the serial port The baud rate is consistent with the baud rate of the recorder.parameter:Input voltage 3.3V ~ 12V (recommended for 3.3V ~ 5V) The memory format is FAT32 and supports up to 64GB of memory UART serial interface Baud rate adjustable The default bootloader is pro mini atmega328P 5V 16mhz

• ★support to store fat16 / fat32 format tf card, storage capacity up to 32G,has a simple command line interface.
• ★on the computer to change the tf card config file (if the new card, insert the card after the first power, which will automatically create config file), you can change the settings, such as baud rate. You do not need to buy any special tools to change the serial port settings to make use of your needs.
• ★three modes: new, add, command.baud rate can be set to 300-1000000bps.
• ★guaranteed to run at least the connection for vcc, gnd, rx.two led lights indicate the running status.
• ★ input voltage 3.3V to 12V, preferably 3.3 to 5V.free current 2ma, the maximum recording rate when 6ma.
