ESP-01 USB Programmer Module

This is a demo of the ESP-01 USB Programmer Module.

You can use this to program ESP-01 and the ESP-01S.

This is a CH340-based USB device. You may already have the drivers installed. If not, a simple search will locate them for you.

It's one thing to show you the adapter. But I figured that you'd like to see it work.

Contrary to what is being posted online, you can get the ESP-01s to blink. Older versions of the Arduino IDE did not have an option to change the BUILTIN_LED pin in the board setup, so you had to do it in the sketch.

The 1.8.12 version allows you to select the pin without altering the sketch.

I have used larger ESP8266 boards with much success, have some that have had components running for three years steady now. I bought a few of these from Temu thought they were super cool. Built a homemade programmer WORK, tried programming through Uno WORK. Watched your video and purchased the exact same board from Amazon. WORKED INSTANTLY! Anyone having trouble with these boards, do yourself a huge favour and just pick one of these programmers up, mine was $14 and came with a ESP8266-01S (the S has better range than the standard 01). Thanks so much for posting video.

Hi. I followed the exact same steps. The COM5 is correct. But get the following error.

esptool.py v3.0
Serial port COM5


A fatal esptool.py error occurred: Failed to connect to ESP8266: Timed out waiting for packet header
