Details
A small single-core S2 board with native USB, which is the interesting part: it can present itself to a computer as a keyboard, a mouse or a mass-storage device without any extra hardware. Good where board space is tight.
Note the S2 has Wi-Fi but no Bluetooth — if you need BLE, take the plain ESP32 or an S3 instead. Also 3.3 V logic, not 5 V tolerant.

Blink, and print over native USB serial
// No external wiring. On native-USB boards the serial port only
// appears once the sketch is running, so give it a moment.
void setup() {
Serial.begin(115200);
delay(2000); // let the USB CDC port enumerate
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
digitalWrite(LED_BUILTIN, HIGH);
Serial.println("on");

digitalWrite(LED_BUILTIN, LOW);
Serial.println("off");
