Makers around the world use ESP8266. It revolutionized the creation of systems that use WiFi. Now is the time for the successor. ESP32 is a stronger successor, at an affordable price.

In addition to Wi-Fi we get support Bluetooth Low Energy (BLE, BT4.0, Bluetooth Smart) and 32 GPIO pins. In our opinion, ESP32 is an unquestionable pretender to be the king of the IoT platforms. At least in the coming years. A powerful dual-core processor, huge amount of operational memory, exceptional energy efficiency clearly speak in favor of this platform. It’s all at a relatively low price and programmable from the Arduino IDE level. Could it be better?

Prototyping
