As of January 27, 2023 - This product has gone through a pretty significant revision which requires firmware updates! The TFT display uses different initialization code (otherwise it will appear offset and inverted) and the microSD holder is also now push-pull. The previous version of the holder was the push-push type.

We've also updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen. This new version is plug-in compatible (same pinout and PCB shape) but the TFT requires new code compilation and upload!

Because of the different display versions, you will need to pay attention to the way you initialize the driver for the language you will be using it with.

It's easy to tell the difference if you know what to look for. On the reverse side of the TFT, the Revision A version has a larger chip on the back as well as an A inside of a circle in the upper-righthand corner:

On the reverse side of the TFT, the Revision B version has a smaller chip on the back. The display is plugged in on this revision and it has a B inside of a circle in the top center:
