#34 ESP-01/ESP-07 4Mbyte Memory Upgrade and OTA

In this video I show how to change flash memory chips in ESP8266 ESP-01 and ESP-07 modules. I show how you can check memory size with your Arduino IDE and use ESP-01 now for upload over the air.

I've just been sent here on a link from the HP PSU video in 2020 - amazing the difference between your tone of voice/presenting style in the last 5 years ! Barely recognised you :)

5 years later, and it's still a useful video!

Seven years on and I'm first finding your video. Thanks Andreas, excellent as always!

Just purchased your "Kolban's Book on ESP8266. Best five bucks I have spent in a long time. I recommend this book to anyone tinkering with the ESP. I have managed to get a web server running and some code to send emails but this book will take me much further. Thanks.

Hello Andreas. I'm from Brazil, I've changed the flash memory from 1 MB to 4 MB on the ESP01 and it worked perfectly. Now I can do the OTA, which was impossible with the original 1 MB flash memory. Thank you so much for the tip and keep up the good work.

This video made us understand why ESP-01 is impossible OTA, even though ESP-12 is possible. Thanks nice video.

I have been looking for someone like you for over a year. You make wonderful videos, clear, precise and well thought out.

I have subscribed and look forward to watching lots more.

Thank you so much kind sir.

I'm french and it's very easy to understand your english! Very great video, I suscribe!

I've upgraded the esp-01 memory on many boards, but, never on the -07. However, , after reviewing your video, again for the nth time, I'm ready to try it on my esp-07. My local library has a hot air tool in the maker space.

Sir, you are great. I was wondering how to make OTA for esp-01. You helped me much.!

[XerotoLabs]

that's very nicely done . so very cool. I know I need to get a heat gun, and you just added an other good reason to do it .

Thank you for this videos, ,

Really2 great and clear explanation, ,
Make more ESP8266..
I'm still beginner but after watch this channel i'm pretty sure will make project with IoT functionality..

Excellent tutorial - thanks for sharing !btw .. love your accent :) kind regards from Mannheim, Germany

I think I may have purchased the wrong flash. Do you happen to know the difference between the W25Q32BVSSIG and the W25Q32FVSSIG? I installed a W25Q32FVSSIG and it's not working, unless I have to do something other than write to the chip as normal with the Arduino IDE. Thanks for your time and videos!

Wie immer, gut erklärt und schicke Lösung. Den Deckel kriegt man mit Murks gut weg. Ich werde in Kürze SRAM huckepack auf das Flash löten (Audiobuffer für einen Internetradio). Der SRAM-CS-Pin wird zur Adressunterscheidung hochgebogen und auf einen GPIO verbunden.

Love your videos. Very informative!! Keep it up:)

Hi Andreas, Thank you for this video. I need to get a hot air set up now ;-) FYI the link to the memory upgrade chip has gone 404. Any chance you could update the notes to include the chips details please?

[asiw]

I do not have a hot air gun at the moment but it would be a nice christmas present to myself. Have you covered them in another video or can you suggest a supplier and size/power (kw) that I would need for soldering SMD's?
Many thanks
Arthur

awesome, this is what i need right now

Yet in 2020, it is very rare to see 16MByte dev kit version in the market
