Teyleten Robot ESP32S ESP32 ESP-WROOM-32 Development Board 2.4GHz Dual-Core WiFi +Bluetooth 2 Function Microcontroller for Arduino (ESP32 30P, 3PCS)

I recently purchased a set of three ESP32 WROOM-32 modules, and I must say, I am thoroughly impressed with their performance and capabilities. These modules are a game-changer for anyone involved in IoT projects, offering a wide array of features and impressive specifications.Let's dive into some of the key specs of the ESP32 WROOM-32:- Dual-core Xtensa 32-bit LX6 microprocessor, running at up to 240 MHz- 520 KB of SRAM and 448 KB of ROM- 4 MB of flash memory for storing code and data- 802.11 b/g/n WiFi and Bluetooth 4.2 (BLE) connectivity- 34 GPIO pins, supporting various interfaces like SPI, I2C, UART, and more- 12-bit ADC and 8-bit DAC for analog signal processing- Cryptographic hardware acceleration for secure communicationThese specifications make the ESP32 WROOM-32 a powerhouse in the world of IoT. The dual-core processor enables efficient multitasking and high-speed execution, while the ample memory allows for complex applications and data storage. The built-in WiFi and Bluetooth connectivity make it easy to integrate these modules into wireless networks and communicate with other devices seamlessly.Upon receiving the modules, I ran a comprehensive health check on each one, testing various aspects such as chip information, memory, flash memory, WiFi connectivity, and internet connectivity. I'm thrilled to report that all three modules passed the tests with outstanding results, demonstrating their reliability and performance.Setting up the ESP32 WROOM-32 modules with the Arduino IDE is a breeze, even for beginners. Simply follow these steps:1. Install the Arduino IDE on your computer.2. Add the ESP32 board package URL to the Arduino IDE preferences.3. Install the ESP32 board package through the Boards Manager.4. Select the "NodeMCU-32S" board from the "Tools" menu.5. Connect your ESP32 module to your computer via USB.6. Select the appropriate port from the "Tools" menu.7. Start programming and uploading your sketches to the ESP32 module.With its impressive specifications and ease of use, the ESP32 WROOM-32 opens up a world of possibilities for IoT projects. Whether you're building smart home devices, wearable sensors, industrial control systems, or anything in between, these modules provide the necessary computing power, connectivity, and flexibility to bring your ideas to fruition.In conclusion, I wholeheartedly recommend the ESP32 WROOM-32 modules to anyone embarking on IoT projects. Their powerful specs, reliable performance, and compatibility with the Arduino IDE make them an excellent choice for both beginners and experienced developers. These modules are a must-have for anyone serious about IoT development.

No issues, great price and was able to code them and install them with ease

Works awesome but on one of the three boards I got the micro USB port is kind of defective. The USB plug doesn't stay plugged in very tight. It makes enough contact though to connect to the board.

This works great if you are wanting to get into C# and nanoframework on embedded processors. these have the blue led on the board on gpio2. There is almost NO documentation for this online as it's a knockoff of a knockoff of a knockoff. there is only a single jpg of the board pinout floating up in the questions that is a link to a google drive location. For a cheap start these work. Be aware that they dont have the full amount of memory so you are not going to do everything you can on a real esp32-WROVER or real ESP32-WROOM. They are trying to claim they are genuine but the laser etching on the tops is nothing like the real ones I have. And the real ones are 3X the price so I knew I was getting something cheaper.These are great to tinker with and for projects. and awesome to give to friends wanting to get started down the path of programming ESP32 with C# and NanoFramework.

I don't plan on using these anytime soon but they look great. Air sealed packaging with a little foam stuck to the pins so they didn't pierce the packaging or get bent. It arrived so fast I was not expecting that kind of fulfillment AT ALL. 10/10 I saved the link in case i need anymore in the future

Awesome boards, fun experiments, and untold amounts of data. These things are beast.

Used it for my own project for college and was able to get an interviews from my project!

Great value IoT board, tested with Arduino 1.8.19 on Debian 12.There is no Teyleten Robot in the library so I used "ESP32 Dev Module" from Espressif's ESP32 Arduino core.The pinout is the same as Espressif's ESP32-DEVKITC board.The SD0 pin is mislabeled SDD.There's a bug in the build where you have torm /tmp/arduino_build_*/includes.cacheafter every compile.
