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)

This is truly my favorite microcontroller packaged into a great development board at an affordable cost.ESP32 works with Bluetooth Classic and BLE for short-distance data streaming. Two of these boards can be connected to each other and share data up to 80 meters away.The Wi-Fi connection is one of the most powerful features. You can connect the board to the internet and communicate with it via a web server. This allows you to make digital applications with physical and analog capabilities. The Wi-Fi communication can also be utilized to make a smart home. You can connect all the ESP32s together and control many different household operations via a Wi-Fi router.The cost is the third big pro. These boards are very affordable for what they can accomplish. This is a must for every circuit lab.I highly recommend this product to anyone who likes building things with microcontrollers.

Super easy to set up and get into home assistant! The Bluetooth things I set up through this work BLAZING fast! Almost immediately!Wish there was an option for a casing, but it works great with a little board I got from Amazon as well.

I’m using this to control an animatronic with bottango and so far it has worked flawlessly. Small size makes it easy to put anywhere and only needs usb c power. Super easy to use. It works just like an arduino.

The product itself works great, only knocking a star off because I didn’t technically receive the board pictured in the listing, rather I received the nodemcu 32-S. The only thing different about this that I’ve been able to see is that the pin labels are on the back which is slightly inconvenient for wiring, and in the arduino ide you have to set it to the nodemcu version. These microcontrollers awesome, and are an extremely good value for their cost. I’m using one of them to monitor switch states and send them wirelessly via ESP-NOW to another one that’s hooked up to a raspberry pi.

I've been playing around with these and so far no issues. For communicating with your IDE software, you can get read the chip number off the board. You might also need the USB to UART drivers installed. The software is free and readily available.

I bought the 5 pack of these, and initially the two that I've tried out of the pack I thought were working fine. Accepted programming and ran as expected. Until I went to move them to their actual intended work area in the other room, that's when it was discovered that they could not maintain a solid connection to my wifi. Bringing it back into my office, it jumped right on, so I open up the router and look at the connection status and see that the device is at a horrifying -75 dBm while just 4 feet away from the broadcast router. Moving out to the intended work area and if I angle it right, it would hit into the -80 dBm area if it had a connection at all, and then drop if it moved again or something else (like foot traffic) got in the way. Ultimately these will not work for my intended use. Maybe they work ok if you don't need to maintain WiFi with the device with distance, but if you do need that ability, this is not the board for you.

No problem to quickly get up and running within the Arduino IDE environment. Using this microcontroller to build a remote control car with my grandson.

Standard 30-pin ESP32S board. Of note: This uses the micro-USB plug, not the USB-C plug. Works. Flashes.
