    Hello,

    as I can see from the OpenLog Hookup Guide https://learn.sparkfun.com/tutorials/openlog-hookup-guide

    the UART interface is designed for 3V3, not 5V as are on the CONTROLLINO pin header.

    So, maybe you have already destroyed your OpenLog.

    What exactly do you mean by “not working”?

    What is your test setup? What have you tried up to now?
