Teyleten Robot ESP32S ESP32 Development Board 2.4GHz Dual-Core WiFi +Bluetooth 2 Function Microcontroller for Arduino (ESP32 38P, 3PCS)

Good bang for the buck. I'm using these as remote temperature sensors via ESPHome and so far, so good. You don't get any documentation with these but if you've worked with any of the other ESP32 devices like the WROVER, you'll feel right at home ('cept for this one has 30 pins - you can buy them with 38 pins, I wanted the smaller form factor). Working on making them battery powered so I don't have to keep them plugged in - I'll update this review if i run into any issues there but I don't expect any. Arduino IDE or Thonny, seems to work just fine.Pic is a test of a cheapo sensor, going to use better ones that will require some soldering, final version gets soldered to a PCB board then 3D print an enclosure for it all and test with and without a battery.

Great build quality, amazing size, and works very well on a larger breadboard. Works very well and integrates with components very well! The product demonstrates exceptional build quality and an impressive size, making it highly effective for use with larger breadboards. Additionally, it integrates seamlessly with various components, ensuring optimal performance.

These are half the cost and 10X the clock of an arduino and while they are development boards, they are cheap enough to use for small production runs. That, and the plethotra of built in peripherals is staggering. wifi, blue tooth, i2c, touch inputs, ADC and DAC. roomy RAM and flasj. USB power and coms. The only downside is they are a 3v3 part so data may need to be level shifted. (Not always though) I drive a 4988 step driver from it without level shifting.

Using these for wled and they perform great!

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.

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

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

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