 The ESP32S2 rover is a low-power 2.4GHz Wi-Fi module with a bunch of additional features in a compact RF shielded package. A couple of minutes with a hot air rework station will allow us to take a peek inside. And inside we find... That's right, more electronics. Arranged in what appears to be the aerial view of an office parking lot. Specifically, we can see clusters of passive components outlined by registration marks, the actual ESP32S2 chip, its timing crystal, and finally the PS-RAM and flash memory chips.
