Can this adapter be used to program an esp32 module?
With pio how do you get the auto-flash mode to work? i can manually jumper it but bought this because of the auto function.
This autoflashes firmware? Even using esptool per espressif using this in a usb port the chip shows gibberish...any steps or docs for it?

Works fine, just as it should

Much easier than the ttl boards where you have to use jumper wires. I had one already like that, then saw this and love it.

Maybe the best thing since sliced bread

If you have more than one of those ESP-01 or ESP-01S modules on hand, and you've been programming these using a cobbled-together circuit (see above, LOL), you owe yourself the 'luxury' of one of these adapters. OMG! These are so nice. No problem whatsoever programming through the Arduino IDE, no timing problems pushing buttons or pulling pins low, etc. They just work, and fingers crossed they will for years to come.

Easier Programming ESP8266

This device makes programming ESP8266 so much easier. No more manually resetting the ESP8266 and changing the selector switch every time you download a sketch (USB - Red version). Just Build and Upload and away you go. ESP8266 auto resets and starts running your code.

Cheap, Solid, No Surprises

Exactly what I ordered. A cheap, functional and well designed ESP8266 programming board. The only thing to note is that it comes with an ESP8266-01s. Functionally the same as the ESP8266-01, but worth noting as there may be minor differences. If you care, you know what they are. If you don't, then you will receive exactly what you expected.

Huge timesaver...

Great timesaver - easy to use - no reset switches to bother with, etc.I am new to all things Arduino and struggled to flash an ESP-01 boards I have with just the Arduino IDE based on wiring setups I saw on YouTube, etc. This device takes away all that extra work.Just a couple of notes if your run into issues getting setup:My first attempts on one Windows 10 PC weren't encouraging - Timeout packet errors, board not found errors, etc. when I attempted to upload a sketch. The setup doc link gives very basic instructions on setting up the device. I tried another Windows 10 machine I have and it worked right away - basically plug and play!I had inadvertently set the Reset Method for the Generic ESP8266 Module in the Arduino IDE to "no dtr" based on bad advice on the problem PC (should be dtr aka nodemcu). I also manually deleted the CH341 drivers and reinstalled them from the link provided in the vendor description. Problems corrected.

Better than the other 2 I tried - so much. Worth the extra $1 (if that). By far.

This is better than 2 others I tried.Works with both ESP-01 & ESP-01s.Has as extra header, so you can connect to a breadboard while connected to the ESP-01(s) - soooo handy (though I wish they were on opposite sides...You don't need to unplug it & replug it in to program.I don't think you even have to press the reset button, it just works - programs, then resets & you can connect over serial.One I tried (Black one with yellow connector from MakerFocus) wouldn't program. You have to solder GPIO to GND to get into programming mode. I soldered in a button, but was janky & not ideal.Another I tried (Red one with yellow connector from WishIOT) has a switch, which helped, to switch from programming mode to serial mode that basically jumpered GPIO to GND.But this is just so much easier - none of that headache. Just works. (after you figure out all of the SW headache, but the HW just works...)

Was worried about ordering something without ratings

This product works great, was kind of skeptical about receiving a working product considering just about all the other programmers out there are adapters and not really programmers. This is a programmer, and software handles the button pushing, so no pushing button to upload from arduino IDE. The ESP01s module said 4mb flash, I thought no way its a typo, its no typo, it really does have 4mb flash. Used arduino IDE with Windows 10, no problems.

Useful. Programs and runs an ESP-01 without fuss and bother.

Plugged an ESP-01 module into this adapter, then plugged it into my laptop. Downloaded an flashed the ESP-01 with micropython. No need to push buttons.Logged in with a terminal emulator.

Perfect für Prusa Mini

Zuvor hatte ich mit dem Original Prusa WLan Modul ständig abstürze des Prusa Mini. Mit diesem Modul hier (4MB Cache!) läuft es jetzt ohne Aussetzer !

Handy for ESP-01S programming with breakout

Reviewed: Stemedu 2PCS USB to ESP8266 Adapter Module ESP-01 Prog ESP-01S ProgrammerESP-01S are really, really small. The trade off is you only get two GPIOs unless you try really hard with the RX and TX connections. However 1 wire only needs one GPIO for lots of devices, eg Dallas DS18B20 temp sensors.This board has a breakout for all eight pins, so if you have USB power handy to where you need this thing eg a computer room then its a very cheap way to add a set of temperature sensors.So far, for me the programmer has just worked and you simply forget about programming vs normal mode.

Corrisponde esattamente alla descrizione

The media could not be loaded.  Quanto ricevuto e' perfettamente aderente alla descrizione del prodotto sulla pagina Amazon.Il modulo ESP-01S ha una flash memory di 4MB(*) (32Mbit) come confermato da verifica(vedasi immagini allegate), il chip CH340 e' presente sul Prog Downloader Stemedu come confermato via software.L'upgrade, il download ed il backup della firmware(AT e/o Micropython) non richiede alcun intervento di setup sull'hardware, come personalmente verificato.L'unico appunto riguarda il prezzo, che a mio parere e' eccessivo; quindi 4 stelle.(*) permette di installare la firmware Micropython per flash size >= 2MB avente inclusi moduli quali urequest ed ussl - non presenti nella versione per ESP-01S con flash da 1MB

Funktioniert super, esp01s hat 4MB (qio) flash

Funktioniert super, 4MB ist optimal für grössere firmware wie WLED.Einen Punkt abzug weil der download link für die dokumentation nicht funktionert.

Convenient for ESP8266 programming

ESP8266 pins are horribly laid out and not breadboard friendly. You can use hookup wires and/or program it without this but it definitely makes it a lot easier. Annoyed I didn't get it sooner, low price makes it worthwhile if you're planning to do projects with these little ESPs.
