DIYmall ESP8266 ESP-01S WiFi Serial Transceiver Module with 4MB Flash

Installed the board, updated the firmware on the Mini, and now I had Wifi capability. Easy to transfer files over to the Mini+ now via PrusaLink or PrusaConnect through Prusaslicer. Wish I'd bought one sooner, though really I don't know why the printer doesn't come with it in the first place.

I installed this in my Prusa MINI+ running FW6.2.6. To activate a PrusaLink connection between my computer and printer I hand-entered the WiFi username and password using the printer's WiFi Wizard. Then, I typed the printer's IP address into my computer browser's command line, this opens PrusaLink. There, I entered the printer's username and password found in the printer's PrusaLink menu. When PrusaLink opens in the browser, simply drag a *. bgcode ready for printing into the File Upload field and it begins transferring to the printer. The printer asks if you want to print after the transfer is complete .

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.

I set this up and it connects with my Arduino UNO on <SoftwareSerial.h> with 9600 baud. I originally connected the Arduino Tx pin to a voltage divider with 10K and 20K to send a 3.33V signal to the ESP8266 Rx, but it was too much resistance and my signal didn't work. I changed this to 1K and 2K to get 3.34V measured signal to the ESP8266 and now it works great! Sending the ESP8266 Tx to the Arduino Rx pin worked fine as 3.3V is enough to trigger a high signal on the Arduino. I set it up the Arduino to use a DS18B20 temperature sensor to report to the ESP8266 website.

As far as product getting here on time and being well packet, and fully funtioning, perfect! Great seller great quality and packaging. Now, as far as the module itself, it is quite hard to work with, if you're a beginner like myself, you'd be better off getting a 5V module (this is 3.3V so you have to worry about stepping down voltage if your system is 5V) and that is more breadboard friendly, such as other models of the ESP8266. There are many out there, just check it out. On the other hand if you know how to work with this module, it's the most inexpensive and thus the best option to put in a final project that you don't want to spend too much on.

LITTLE POWERHOUSE! This ESP8266 module is great for beginners and experts alike. Whether you just want to play with WiFi connected Arduino projects using AT Commands, or load Arduino IDE sketches to it to act as the microcontroller, this will do the trick. The 1MB Flash provides plenty of space and when I ran AT+CWLAP scan with it, it detected networks in my area I didn’t even know existed. Very Strong Signal! I also had it running everyone’s favorite ‘BLINK’ sketch in no time. When you do buy one (or 10) of these, I would recommend also grabbing one (or 10) of these little gems to pair with it/them - “DIYmall ESP8266 ESP-01 Breakout Board Breadboard Adapter PCB for Serial Wifi Transceiver Network” over at https://amzn.com/B01G6H46UK You can thank me later for the suggestion and you definitely will thank DIYmall for offering them. They make working with the ESP8266 that much easier! Happy Prototyping!

Bought to upgrade my Prusa Mini - Works perfectly well. Drop in and upgrade your firmware.

Very difficult to get to work with arduino though I did eventually get it to work only to find out it wouldn't do what I needed, which was downloading google calendar data directly from google, which requires ssl, and this does not support that. I'm not basing my rating on the ssl issue as I understand why it doesn't have it, but the difficulty of getting this to work was almost unbearable. I spent a lot of time on it, though I'm sure there is a lot more examples and docs out now that my make it easier. Also, I tried the built in online update command on it and it put it into an infinite loop that I have not been able to break it out of. I tried resetting it, leaving it disconnected from everything for days, everything that I can and it won't break out of the cycle. I eventually gave up and bought a replacement.

Good Product . I had a few problems for uploading my program onto it for the first time .. but then google helps . If anyone else is having a problem a problem then the GPIO pin has to be made ground then reset then release them to enter flashing mode . And through the pins are 5 V tolerant they are meant to work with 3.3 V ,so use them at 5 V at your own risk . And the problem which i face often . Power Issue . The Module draws a lot of current , that why best is to use external source (with common ground very important) .

This chip worked great. I was able to plug it directly into my prusa mini to add wifi capability with no issues.

Excelente compra, tamaño perfecto

Did the trick for my printer.
