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)

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.

This was an awesome beginners project! It was fun and worked efficiently and fast. Has many uses for kids and adults. And the projects for them are very well versatile and can work with almost everything.

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.

These were the first ESP32s I ever bought, so I didn't really know what I was looking at or for, but they ended up working very well. As I learned more, I realized there are many different types, and it was hard to know what type this was. As someone else mentioned, I ended up using esptool command line tool. Here is what I got in hopes it makes someone's else's journey a little easier. Based on documentation, best I can tell this is the original ESP32 Series, not the S series. Here is what esptool tells me about mine: Chip type: ESP32-D0WD-V3 (revision v3.1) Features: Wi-Fi, BT, Dual Core + LP Core, 240MHz, Vref calibration in eFuse, Coding Scheme None Crystal frequency: 40MHz That confusion aside, they worked great for what I needed, they came package well, with Styrofoam pads protecting the pins and all 3 were in working order. Deducted 1 star for the confusion around knowing exactly what you are getting.

I bought a set to use as a Bluetooth proxy with Home Assistant and things that were unstable and laggy are now basically instant and perfect. Love it and now I'm trying to figure out how to use the others. Also, these are quite small and super easy to power. Basically, super great value. Oh, if you have issues use ESPHome to flash projects onto your ESP32? Make sure to download the drivers. That threw me for a loop for a bit.

Successfully flash blinky on zephyr 4.4.0. Development board name is doit_esp32_devkit_v1.

Two of the three I ordered no longer connect to WiFi after a month. They drop the connection even when right next to my router. Happens intermittently for a few minutes, then drops off the network entirely unless rebooted. After several power cycles, I’m lucky to get them reconnected for a minute or two. One even stopped connecting via serial port to my computer. I have several others from other manufacturers being used in the same fashion, and I’m only having issues with this bunch. It’s a minor financial loss, but I’ve spent hours prototyping devices and projects that I eventually soldered before installing them, and now I’ve spent many more hours troubleshooting only to realize that it’s not me, it’s the hardware. Consider purchasing from another seller and manufacturer, even if they cost a few dollars more. Thankfully I should be able to desolder and swap in some more reliable boards.

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.

Really useful microcontroller

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

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.

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

Ok
