HiLetgo 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 for Arduino IDE

Works well with arduino iot platform. Blynk does not support this board.

Working 100%

Esp32 works as expected however i wasn't able to work the touch sensor work as i had seen some online where touching the GPIO pins changes the capacitance and registers an output (i hope I'm making sense). I believe it's nothing major (probably my lack of skills with these microcontrollers) as I've made other stuff work with it.

Works perfectly

Gets really hot and doesn't function at all

It's such a letdown, I was trying to make a smart home system project and half of the pins don't work.

I have tried every method described everywhere including YouTube but have not been succesul in booting the device.

Received item is not what is on pictures, it should have 18 pins I got only 15, I found items similar or identical to this on a chinses site for 2 euro. On top of this it seems it's not working. Looks like a typical scam, when people resell items from Chinese sites here for 10 times of a price.

Acheté pour tester afin de réaliser une "station météo" avec de multiple capteurs (afin d'en avoir dans chaque pièce de la maison et à l’extérieur). Ce module rend la fabrication d'objets connectés relativement facile grâce à l'IDE arduino et tout son ecosysteme. J'ai pu réaliser une version brute de ce que je cherche à faire en moins d'un après midi, malgré aucune expérience au préalable avec l'ESP32, en utilisant des librairies préécrites et un peu de logique. Cela permet d'imaginer une multitude de projets connectés pour les futures journées pluvieuses ;)

This is insane value for the cost. The specs on this are completely ridiculous. It comes with a detailed Pinout Diagram and Schematic of the Circuitry. USB-to-UART, AMS1117-3.3v, VSPI (High-speed SPI bus mapped to MOSI {Clock-Speed up to 80MHz}), Touch Capacitive Pins, Digital-to-Analog & Analog-to-Digital Converters, WiFi & Bluetooth, etc. Capable of both “Master” & “Slave” modes. Common uses would be for TFT & OLED modules, SD Card modules, Sensors, Radios, Transceivers (lower ranges unless rigged with accompanying equipment), Transmitter (middle-man as “slave” unless low range and non-real time processing). Overall extremely exceptional buy if I have a need for another arises and they are still around this price it would be worth buying again.

Good quality controller. Works just perfectly.

Board works fine, though as some others have found, I needed to hold IO0 switch to upload from Arduino IDE. This can be solved by adding a 1uF capacitor from EN to GND. The details can be found if you search for "ESP32 Reset To Bootloader Issues on Windows."
