ESP32 Wireless Wifi Bluetooth Development Board unsoldered

The ESP32 is an advanced low-power IoT sensor hub, offering superior capabilities compared to the Arduino. With its dual-core 32-bit LX6 microprocessor running at 240MHz, it includes built-in WiFi and Bluetooth and can be programmed via the Arduino IDE. This makes it ideal for a variety of IoT applications that require wireless communication and processing power.
