Description
ESP32 chip features
- Higher processing power and low power requirements compared to its predecessor ESP8266
- System on a chip (SoC) family
- Allows communication via WiFi 802.11 b/g/n and via Bluetooth BLE and low-power version 4.2
- Small size is a big advantage – 18 x 25.5 x 3.1 mm and dedicated to use in compact projects
- ESP32 wireless communication modules form the basis of IoT (Internet of Things)
