ESP32 | NodeMCU 4Mb | 240Mhz Dual Core | WiFi | Bluetooth

8,98

The ESP32 development board (actually a super-fast 240Mhz Arduino with WiFi, bluetooth and 4Mb flash) is ideal for IoT (Internet Of Things) projects because it features on board WiFi and Bluetooth. Simply program via the Arduino IDE. One-time installation is required. Search Youtube for ESP32 in Arduino IDE installation.

This module lends itself ideally to ESPHome, Tasmota or WLED, the possibilities are unprecedented!

The ESP32 is the successor to the successful ESP8266 but is faster and is now equipped with Bluetooth and a lot faster.
This ESP32 board has:

  • 18 Analog-to-Digital Converter (ADC) channels
  • 3 SPI interfaces
  • 3 UART interfaces
  • 2 I2C interfaces
  • 16 PWM output channels
  • 2 Digital-to-Analog Converters (DAC).
  • 2 I2S interfaces
  • 10 Capacitive sensing GPIOs

The beauty of this little board is that you can use it in multiple ways as far as WiFi communication is concerned.

  • As a mini access point
  • As a WiFi client
  • As Web Server
  • Peer-to-peer with ESP Now We want to explain that last part. ESP NOW is a technology that allows modules to communicate directly with each other via their MAC address. In addition, there is also a message back whether the data has been received making it possible to properly check whether messages arrive and validate this.

ESP Now allows you to work very modularly, and it’s also blazing fast. This way you can run your program on one ESP32 while letting other ESP32 boards just react and be an extension of your GPIO pins, so to speak.
1 ESP32 can communicate with up to 20 other boards.
