Hi folks, now I'll teach you how to make your programmer to the ESP-01 and ESP-201, (perhaps serve with other models) using an Arduino UNO, a few cables and optionally a button and a slide switch, in my case I use them because I had available, with this programmer able to upload the Arduino sketches and any other firmware (AT, LUA, Espruino, etc).
Okay, let's start, first do the following circuit.
Optionally if necessary can place a 100n capacitor between Vcc and GND and if you're a fan of security, you can put a divider or Logic Level Converter voltage between RX and TX.
1.- Connect the Arduino/Genuino UNO.
2.- Put the ESP-01 in Flash mode, set the slide switch to GND.
3.- Push the Button reset.
4.-And open the app for Flash, that you like.
Note.- I test with:
a.- Flash tool 2.4 -Link-
b.- ESP8266 Flasher -Link-
c.- Arduino IDE -Link-
That is all!!!
Using Arduino IDE
Using Flash tools to return the ESP-01 module, to AT commands.
Using Flash tools to uploap LUA firmware
