Thank you so much! It helps me a lot. I was hopeless why it doesn't and when I soldered it like in the video, it works!

Nice! I soldered a Button right on the pins, makes a nice and sturdy connection.

Works very well, exactly the info I was looking for! Thank you very much!

Thanks the programming connections was awesome short and nice!

I was about to trow the parts out of the Window. But then it worked as you said. Thanks man!

I know it's an old video but thanks for the run through. I shorted a couple of the pins based on another video, not shown here but you mention it further down in the comments. The only issue I had was I got weird icons on the Serial Monitor until I changed the baud rate.

SOLUTION! The USB programmer I bought had a program/UART switch, but wouldn't work because the chip enable (CH_PD) pin wasn't connected to VCC! (+3.3v). An easy fix, now that I knew the problem. AliExpress buyers beware! Thank you again Csongor for a great informational video.

Exactly what i needed to know, thank you!

Thank you so much! I accidently got a usb to uart converter insted of usb to tts, and this helped me a lot! Thanks again!

Thank you SO much for doing this video. I really needed this information.

Thank you. I was missing the part with the switch, and was wondering how the board would know if I want to program or not. Well, now i know there is NO MAGIC ;)

Thanks for the video! I wwas trying to flash ESP01 but didnt know about the jumper and buttom! Now is working!!

The clearest explanation ever. Thanks alot

many thanks for this .... good video quality as well.

Thank you, I got the same "programmer" and was wondering why it wasn't programming. This fixed it. Might I make an improvement though. Wire a 2nd button to the reset pin (pin 6 next to vcc, look it up in the datasheet) to also pull the reset low as well. So to program hold reset, hold program, let go of reset, then let go of program. This means you don't have to unplug and re-plug every time you want to program, just do a little bit of button tango.

Works brilliantly. Thank you.

Thanks for your published awesome video as always, appreciated. :D

Just for safety instead of a jumper wire for the CH_EN use a 10k resistor... that will limit the current and be safer

thanks for the vid, it got the ch340 into programmer mode.

Thank you it helped me to program esp-01.

Excelent, you saved my day and i hope the christmass tree lights as well ;-)

i soldered a 2-pin header, the pins are L-Shaped so the non-soldered ends of the pins are of the side of the board. i added some hot glue to hold the plastic pin separator. then i use a jumper as a switch. looks like it will be a durable solution. Now i'm trying to figure if i can use it as an ftdi to burn a bootloader into a "blue pill" stm32F3

worked like a charm, thanks

thank you Csongor. Really helpfull video

I've resolved just shor-circuiting the pins with the button thanks to a stapling point (that I could put in place or remove really easily), without needing to keep the button pressed. Furthermore, in some versions of the programmer (mine, for example), VCC and CH_PD (CH_EN) are already short-circuited. In any case, thanks a lot for the tip!!!

Dude, you're a genius. Thanks! :-)

Nice Work great images.

I did the same mod just last week. My UART device looks exactly the same as yours, but its CH_PD was already connected to VCC. So the jumper was not needed.

Thanks a lorT!!!!. want to put the esp01 in a protoboard how can I make the program work without the need of the usb?

Thx... Man you safe my life

Thanks, it help me a lot

Great Video! Thank you so much !!

what is the arduino alias for the gpio (0,1,2,3) pins for programming the esp 01 with arduino ide ?

Thanks! You’re awesome

Very useful, thanks. I thought I had bought a programmer when I bought this lol.

Thank you man!

I was expecting, by title of the video, that you had made a wireless uart and programmer, that would be cool.

Thanks very much, worked great :)

Thank you so much !

Thanks! I'm finally able to upload a sketch to the esp. But, being a newbie, I still don't know what to do next. How do you get the serial monitor working, and get the esp's IP address and all that (like on 4:40 in the video)? Thanks

I got the same USB adapter. I do not need a bridge to enable the chip. I read about that some adapters have 5v on TX and RX. My adapter have only 5v at the Rx pin. I can flash without any problems. But everywhere they wrote about that this will damage the chip. We will see. That´s only for information.

Thank you Arnold! It works!!! :* :* :*

Hey nice video ! But need to same thing for ESP8266-05 or ESP05 I mean. There are no content for it and still can't program it using serial uart.. Hope you can do it

Why you didn't say about driver for CH340?

I have a question for you my friend: Do you know how to program the ESP6288 with AT commands using this USB serial adapter? Thank you!

Thanks!

Hey!.. I did the same thing to my UART to program the ESP8266 01 device through Arduino IDE in MacBook Air. But the code is not uploading and it is showing the error as "esptool. Fatalerror: Failed to connect to ESP8266: Timed out waiting for packet header". Can anyone help me in this issue to sort out please?..

I instantly came here when the board didn't begin programming comms xD

ESP32 and ESP8266... UART0 use for only upload/download firmware, I use UART1 for communication other modules.

hi my programmer looks exactly like yours and i tried your approach with button and jumper ... still same mem failed error and then tried without the jumper still same .. tried to change the reset to nodeMCU still same error .. no idea what else to try ... do you think my PC USB is not a good power source i should attach an external power to the ESP 01? What do you recommend me to try? , i'm able to upload code via old FTDI board but that get messy with a lot of wires so i thought should be much easier using this programmer, thanks

Can you send AT commands when the esp is in programmer mode? I received my esp-01 usb programmer with pin 1 (GND) & pin 5 (GPIO0) soldered together with a single wire. When I send "AT" through the serial monitor on the Arduino IDE, I don't get a response. So I tried the ESP examples to test if it was working, ESP8266 -> Blink example did nothing, however the ESP8266WiFi -> WiFiScan example worked, displaying the available networks on the serial monitor. So I'm unsure as to why the AT commands aren't working or displaying anything on the serial monitor. Any feedback would be appreciated!!

I am using esp 01 adaptor and tried flashing esp8266 but am getting error esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header why is this error coming ?

Good Day sir what drivers do you need to programming the esp-01 or esp8266?

which program do you use to flash the esp? esptool?

Hi following your instruction, probably not correctly, i was able to drop down progs on ESP, but at the end of loading parts via arduino software, at the end i receive "leaving Soft reset" and then nothing work, can you suggest something?

Not very exciting, but I'm able to program with the same serial module without having to tie chip_en to VCC. I just connected GPI-0 to GND and it did the trick.

Can i use Android mobile to programing esp01

Can this be directly used for programming esp8266 12e

VCC an EN is already shorted in the programmer no need that jumper

Sir, When exactly we have to press button? 1. Keep pressed while inserting the ESP in UART module (while Module is powered by USB) OR 2. Press once after ESP inserted and before programming (Module is powered) OR 3. Keep pressed while program being uploaded! What other things we should learn by noticing the behavior of onboard led. 1. After inserting ESP into UART and powered by USB. 2. While Programming 3. After Programmed. How to Shift from Program mode to Communication mode with PC Sorry for many question!

If you're soldering anyway, why not just connect GPIO0 to DTR (pin 13) and RESET to RTS (pin 14) and have fully automatic programming (esptool reset method `ck`). The button solution feels rather tedious.

Sehr cool danke !!! Die Brücke brauchte ich auch nicht
