Yes, the LCD panel has an MicroSD slot but no clock, and the slot is inaccessible from outside the box, hence the “datalogging” card in the back of the case.Wow - seems like a great candidate for an interface PCB to plug all these boards onto - very cheap when bought in bulk
There is no SD card reader on the back of the LCD?
In hindsight it would have been easier to combine the RTC, MicroSD, 12->8 volt buck, and K-line drivers into a single board then have them made, but that process was outside my skill set. Building a dozen of these up from discrete parts seemed reasonable at the time... 50 units is a different scale and I should have regrouped with the increased volume. But these work, and I’m steadily getting through them, so live and learn. Maybe I’ll pull a “Tom Sawyer” and convince my sons how much fun they can have soldering!?
