ESP32 ESP-WROOM-32 Development Board Dual-core Modules with Wi-Fi & Dual-mode Bluetooth
Introduction to ESP32 chip
introduction to programming ESP32 using the Arduino IDE. I’ll show you here how to program an ESP32, with 19-pins on each side, as an Arduino. But also, I’ll show the differences between this type of microcontroller and the Arduino itself. So, in addition to introducing ESP32 using the Arduino IDE, I’ll give you a practical example of how to do a digital reading and digital performance.
ESP32 ESP-WROOM-32 PIN Description PINOUT
Features
- Two independently-controlled CPU cores with adjustable clock frequency, ranging from 80 MHz to 240 MHz
- +19.5 dBm output at the antenna ensures a good physical range
