3PCS ESP32 Breakout Board GPIO 1 into 2 Compatible with 30 Pins ESP32S ESP32 Development Board 2.4 GHz Dual Core WLAN WiFi + Bluetooth 2-in-1 Microcontroller ESP-WROOM-32 Chip for Arduino

Fits my Elegoo ESP32 perfectly, without having to rearrange the pins.

I'm still learning how to program with these things but I love them. Just programming with Esp32 is so much easier and the devkit here is as sturdy as it comes. It's durable and definitely well constructed. For the price it's pretty good unit to start out with.

Worked amazing on my project, woukd give more stars if they were available.

Item is a great price for my Wled project, The screw terminal add versatility for easy prototyping, once programed it hooks up to Wifi instantly. and at this price its fun and affordable enough for group projects..

Great little clone of the NodeMCU-ESP32. I would give the product 5 stars, but it uses a CP210x chip for the serial communication rather than an FTDI chip, which is always a downgrade in terms of reliability and stability of buffered transmission over serial. The included screw terminal breakout board includes dupont connection terminals which are very useful for the addition of an additional breakout board on top of the mainboard or for prototyping, it is very much appreciated by a developer like myself. The wifi connectivity is stable and reliable. Overall, this is a good buy for the price, two chips, two board for 20 dollars is a good value. For development on the platformio environment, you should use the NodeMCU-32S board as your board value in the platformio.ini file: "board = nodemcu-32s"

These breakout boards are a nice way to prototype without fumbling with wires. Just load your ESP32 dev module onto the breakout board and start building. This board is versatile as it allows you to use male jumper wires OR solid or twisted wires to connect. The dev module fits perfectly onto the board. My only complaint is that the bottom of the board is sharp - beware. The solders on the bottom will cut you if you are not careful. Otherwise, this is a good purchase.

For a ESP 32 it worked great. I like the board it's on and made it easier to work with my 10 year old to build his first car. The ESP gave him more options and he has thoughts on things to add and the ESP 32 gives him the option to add them in the future

Imaging micropython to the board revealed that it was not an S3 variant that was initially expected. Should have expected this at the price. It should still work for the intended uses for now, so won't dock any stars. esptool.py v4.8.1 Serial port /dev/ttyUSB0 Connecting.... Detecting chip type... Unsupported detection protocol, switching and trying again... Connecting.... Detecting chip type... ESP32 Chip is ESP32-D0WD-V3 (revision v3.1) Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None Crystal is 40MHz MAC: xx.xx.xx.xx.xx.xx Uploading stub... Running stub... Stub running... Manufacturer: 85 Device: 2016 Detected flash size: 4MB Flash voltage set by a strapping pin to 3.3V Quality looks decent, but noticed/tested two cold solder joints on the pins, and one severely bent pin (Docked 2 stars for horrible QA). Once the iron took care of the joints and the pliers corrected the bent pin, I connected it to the workstation to target an installation of blinker (using arduino studio). Unfortunately, this didn't work, as the application kept complaining that it wasn't an S3 chip. So I moved on to testing with esptool to find out that it wasn't an S3 chip at all. If you're considering a purchase of an S3, please look elsewhere. BUT if you're just looking for a cheap ESP32S chip, this may do your project the perfect amount of good! Just be aware that there may be QA issues that need to be corrected prior to use!
