not very easy to use unless you know what you're doing
KT✓ Verified Purchase•October 10, 2023
I was going to use this to allow my arduino to communicate with my device wirelessly, however, considering that I'm a beginner, it was a little complicated to use and YouTube videos weren't really helpful. I also later found out that arduino also has a newer board with wifi capabilities, making this redundant
Firmware updating works but I burned my unit
Mark Serrano✓ Verified Purchase•October 7, 2023
The product works as expected. However mine burnt down though and smoked. It might be my fault because I accidentally inserted the GND pin to the MST pin. I did a lot of firmware rewrite on this because I was having trouble doing a firmware update on another ESP8266 dev board. So this DIYmall is basically my guinea pig. I am able to update the firmware on this thing twice so I know it works and I am able to access the AT commands. I think it overheated due to my "abuse".
Cons:
* Somewhat expensive compare to other EP8266 boards. Well $6 isn't that much really but there are packages from other sellers here in Amazon that sells 4 of these for $14. So that is like $3.50 each. Almosr 50% cheaper..
* It burnt. I am still 50/50 if it's me or the unit
Pros:
* I am able to update the firmware on this thing
* Ultra solid packaging. You can tell they care about their units
By the way I like the DIYmall brand. I like their OLED displays.

PRUSA MINI

Installed in my Prusa Mini. It works! No more USB for file transferring.
Works for Prusca Mini+
Borz✓ Verified Purchase•September 14, 2023
Purchased this based on other reviews that said it works with the Prusca. Worked like a charm with no issues. Such a big difference being able to send prints to the printer without the USB! I really didn't like the USB transfer process but got used to it. Now after being spoiled with this Wifi card, I look back and really hate the USB process now! Big quality of life luxury for less than $10 shipped. Great purchase.
3 worked flawless, 1 was a dud
Russ D✓ Verified Purchase•August 27, 2023
I bought these to use in my Prusa Mini 3D printers to add WiFi capabilities. The first one worked great, instantly connected. The second one just had endless problems and would basically reset it's connection over and over. After hours of firmware reinstalling and troubleshooting, I thought I should swap out the esp32 with the first one and boom! it was working perfectly. I bought two more and those worked great too. Obviously this small an order not a big enough sample size to draw an accurate conclusion, but just know that it sounds like getting duds with these are not uncommon.
