Serial data logger

Hardware
1

Do you know of a small serial data logger that just logs serial data without interaction?

I would like to put it on a featherwing protoboard for debug purposes. Setting the loghandler up for Serial1 on a Boron, B523, Argon … and connect that to a logger module that just logs the data in a huge circular buffer without needing any interaction, for later retrieval.

Thanks,

Would you be interested in a device like the OpenLog?

As long as it does not need commands to start logging, and can keep data without power. Seems great for large amounts of data.

Also interest in a version without SD card, as that can be a source of instability in the field.

@thrmttnw ,

There is a single line text file that you put in the root folder of the MicroSD card which handles all the configuration. So, no commands needed to start logging.

I use these in a couple counters where there is zero cell signal (except ahem - Verizon!) and they have proven quite reliable. I am hoping the cellular coverage picture improves before they wear out.

A data logger with flash memory, but retired - used to be available embedded in resin:

We use a adafruit adalogger. It is in a Feather format, has an SD card and you can rig it to be self powered.
