ESP32 WROOM Wifi-Based Microcontroller Development Board
Series ESP32
ESP32 overview
ESP32 is a prototyping board that is the work of the Shanghai-based company Espressif Systems. It incorporates the ESP32, a microprocessor tailored toward wearable electronics and IoT. It boasts integrated Wi-Fi and Bluetooth, along with an array of inbuilt antenna switches, and ultra-low power consumption. The company released the ESP8266 chip in 2014. Costing only a few dollars, this small chip is able to bridge an Arduino with a WiFi network, solving many issues that early IoT pioneers experienced.
