Looks like they are the next step from the basic Sandisk. thanks

Is there a new recommended micro sd card? It is getting harder to find regular SanDisk 8 or 16gb cards. From what I read on the forum, higher capacity cards might draw more power. These cards are from third party sellers that I don’t really trust: Amazon.com: Sandisk SDSDQM-016G-B35 16GB MicroSDHC Memory Card, Class 4 (RETAIL PACKAGE) :…[Read more]

The Campbell ClariVUE10 eventually developed interval reporting issues with the last library that I mentioned above so I copied the libraries from my old computer onto my new computer because it was the last set of libraries that didn’t have issues.

Thank you for the tip on needing two separate screw terminal boards because each C-FLOUR needing 2 ground terminals each.

Thank you for the confirmation and write up for the sketch setup. I just have the phycocyanin C-FLUOR. This is my first time soldering, so I’m practicing on another board before I commit on the MP screw terminal board.

I have been using android phones to connect a USB C -> FTDI cable to the FTDI port on the mayfly data logger to read data via the Serial USB Terminal app in the field.

Have any of you had success with connecting an iOS device (iPhone or iPad) to the mayfly data logger via cable?
