M5Stack ESP32 Gray Development Kit w/ 9 Axis Sensor

I didn't know this when I bought it, but the gray has more RAM than some of the others. Do your research and decide which specs are right for your project. Even though these are easier than the raw-circuitboard style, they still are not super-easy. Expect to spend significant time setting up your IDE(s), plus trial-and-error about how things work.For example, I had a blast modding the "Space Shooter" project. The mods were necessary because the thing started upside down. Took a bit of digging to find the screen rotation setting for the display driver libs. Lots of fun, and a real sense of accomplishment.
