USB Programming Adaptor for ESP8266
from the Espressif family, I’d like the ESP-01 and ESP-012
This project lets you program ESP-01 and ESP-012 type ESP8266 modules via an FTDI USB interface. An additional connector makes it possible to talk to any other module in the ESP8266 family, using flying leads.This project is very handy, particularly when developing on breadboard or for quick prototyping, as it lets you dispense with switches or jumpers for enabling the programming mode. A simple cable with an FTDI USB–TTL converter lets you power the circuit and transmit the code.
