#77217 Yes. The FTDI can supply up to 50mA at 3.3V which is nowhere near enough to supply the ESP8266.

You need to use a separate 3.3V supply or regulate down from the USB 5V

#77221 You need a supply that is capable of at least 300mA. The average consumption will be much less but there are times when the higher currents must be provided. From what I have read from Expresif documents the rf calibration at startup draws a lot of current. I think that time is a worst case situation.

#77231 Morning.
I put on a stronger power supply (MB102 Breadboard Power Supply Module), and now after reboot of firmware load the red led does stay bright. Woot.

I also changed the script:
void setup() {
Serial.println("Hello world");
}
void loop() {
Serial.println("HIGH");
delay(1000);
Serial.println("LOW");
delay(1000);
}

I still get the Crash:

Questions
What is the correct Library?
Is it a memory size issue?
Is it a Wrong IDE Setting?
Should these be Pre Flashed with firmware?
