Adafruit Industries Feather 32u4 Adalogger, Инструкция по эксплуатации, Страница: 38 / 40

If you really want to make sure you save every data point, put a
logfile.flush();
right after the logfile.print's however this will cause the adalogger to draw a lot more
power, maybe about 3x as much on average (30mA avg rather than about 10mA)
