SparkFun DEV-15164 Qwiic OpenLog
SparkFun DEV-15164 Qwiic OpenLog can daisy chain multiple I2C devices and log them all without occupying the serial port. SparkFun Qwiic OpenLog logs large amounts of serial data and stores all that the project generates for scientific or debugging purposes. No soldering is required to connect the DEV-15164 Qwiic OpenLog, but it includes broken-out 0.1"-spaced pins for a breadboard.
The Qwiic OpenLog runs off of an onboard ATmega328, running at 16MHz using the onboard resonator. The DEV-15164 also supports clock stretching, recording data up to 20,000 bytes per second at 400kHz. As the receive buffer fills up, this OpenLog will hold the clock line, letting the master know that it is busy. Once the Qwiic OpenLog is finished with a task, it releases the clock and allows the data to continue flowing without corruption.
