ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor Integrated with Antenna RF AMP Filter AP STA Compatible with Arduino IDE (3PCS)

Vwry very good one,good price and good quality,wifi worked just fine i set it up with mucropython so easy but the pins was a little weak so be careful removing it from breadboard

Really useful microcontroller

I had a few old Chinese addresses able rgb strips that just had a very basically controller and crappy power supplies. Install WLED on this board and now all the strips are smart light strips and they perform better than some of the other branded RGB led strips.

Ok

Am able to connect sensors and host a server on it!

Great for my daughters uni project

Ok

If you have ubuntu 22.04 and you can't upload anything to your ESP32 equiped with CP2102, here is how to fix it: First run `sudo dmesg -w` and see what happens when you plug your board You should see something like this: ``` [951023.608473] usb 1-6.1: new full-speed USB device number 62 using xhci_hcd [951023.739847] usb 1-6.1: New USB device found, idVendor=10c4, idProduct=ea60, bcdDevice= 1.00 [951023.739852] usb 1-6.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [951023.739854] usb 1-6.1: Product: CP2102 USB to UART Bridge Controller [951023.739856] usb 1-6.1: Manufacturer: Silicon Labs [951023.739858] usb 1-6.1: SerialNumber: 0001 [951023.753463] cp210x 1-6.1:1.0: cp210x converter detected [951023.754508] usb 1-6.1: cp210x converter now attached to ttyUSB0 ``` If some time after connecting you see this...: ``` [951026.615438] usb 1-6.1: usbfs: interface 0 claimed by cp210x while 'brltty' sets config #1 [951026.616472] cp210x ttyUSB0: cp210x converter now disconnected from ttyUSB0 [951026.616689] cp210x 1-6.1:1.0: device disconnected ``` ... it means that your board automatically disconnects. In this case we have an issue with a preinstalled software called "britty", to fix this issue simply uninstall it: ``` sudo apt remove brltty ``` Then reconnect your board and upload your code, it should work. You may have other software conflicting with your board, in which case start with `sudo dmesg -w` to see what's going on... I update my rating because the board actualy does work and is indeed a DEVKITV1 instead of incompatible NodeMCU shipped by some other amazon sellers...

I bought this ESP32 for a digital seismograph I'm working on. The functionality of this thing is amazing. I was able to hook it up to my ADC without any problems, alongside a micro SD card reader. Not only that but I was able to run a local webserver in which I could see my graph. It's pretty fast too, I haven't had any delays with processing data at all. It's small size and very little required power source makes this great too. It's versatility will allow you to pretty much use any type of electrical component with it, and I have not runed into any compatibility issues so far with any of my parts. Only thing I would consider a con would be that you'll have to learn C++ in order to program it. Overall, I would recommend this board for any type of low power project you may need.

Easy to program even if the description is confusing. ESPTool sorts out all you need to know. A little higher than the $5 target price, but 100% working.

I picked these up to make a cheap COB LED strip smart. It only came with an RF remote which is not sustainable. They arrived without documentation, but that isn't a problem for me. My will is stronger than that. They arrived sealed in antistatic bags and looked new. The onboard USB port is a micro USB. I used it to flash WLED and setup wifi. I powered the board and the LED strip from the same power source because they used the same voltage. Then, I used a GPIO pin to communicate with the light strip. It was easier than I thought it was going to be. A heat sink is not recommend because the ESP chip does not produce much heat. They do not include a display. The quality is fine for my purposes. If you are just getting started with something like this, read the WLED site or ESPHome. Step 1. The website will flash the firmware for you.

I bought this because I’m an idiot who apparently enjoys wasting his money, time and effort. I have a bunch of Arduinos but forgot everything I knew about them. I got tired of trying to relearn Arduinos and stumbled upon ESP32 and in spite of somewhat troubling reviews, I gambled! My first evening of playing with the ESP didn’t go well and I was frustrated with no way to k ow if it was SOE thing I was doing or had I received a dud board. Today, I decided to give it a go with an antique laptop… Sure enough, I can say the board works with no weirdness like having to play the hokie pokie with the Boot button-something it seems Might be common. Now that I’ve confirmed comms betwx the laptop and board, it’s time to write some code and make something that will be of benefit, a water level controller! Next up water temp control! Edit:I’m buying more from this vendor! These boards work and if I find something that works, I go back to that trough! Yes, my wife enjoyed laughing at me as I showed numbers changing on my phone. It was much more impressive than making an LED illuminate/extonguish!

It works very good, amazing value for money, good size, usb port is high quality though there are two major problems, the pins bend semi easily and the VIN regulator brownouts very easily (which means its either defective or otherwise)
