Question_1
Hi. I wanted to ask do I need a separate part such as the PL2303 to power ESP8266?
I read that it requires a 3.3v output. The PL2303 has a 3.3v and a 5v output.
I looked at the mbed LPC1768, and it has a 3.3v Regulated Out pin. Does this mean I don't require the PL2303, or do I actually need it to setup the transceiver, through the PL2303?
I've looked at the data sheet for ESP8266. In the setup guide it used the PL2303 part to connect the UTXD port from ESP8266 to the RXD port of PL2303.
UTXD = UART_TXD，sendind; General Purpose Input/Output：GPIO; RXD = Data input from Serial Bus.
I think PL2303 serial bridge is connected to main computer from where you setup the transceiver through sscom32 software?
Is this correct?

Hi Lukas!
I have found the ESP8266 with just the LPC1768 to be a bit flaky. The voltage regulator isn't up to the current and as such it causes reset issues. I'm going back a couple of years now, but I used a separate PSU to power the ESP8266.
Hope that helps
