The ATOM Lite is M5Stack's most proven small controller: ESP32-PICO-D4, a Grove port, an RGB LED, an IR transmitter and USB-C in the same 24 × 24 mm format as the AtomS3 Lite.
It is a few years old, and that is its strength. Almost all of M5Stack's official examples and a large share of community projects are written for the ATOM Lite. If you follow a guide you found online, it very likely uses this board.
Choose the AtomS3 Lite if you want more memory and a newer chip. Choose the ATOM Lite if you follow an existing guide or want the IR transmitter.
A USB-C data cable, and a Grove cable if you connect a sensor.
