ESP32 is a complete, small form factor (SFF) 802.11 b / g / n / e / i (2.4GHz) WLAN plus BT4.2combo solution optimized for low-power, mobile consumer electronics, wearable and Internet of Things (IOT) devices. ESP32 integrates all WLAN and BT functionality in a single package to support a low cost, layout-friendly implementation while allowing flexibility for platform specific customization. ESp32 integrates the transmit / receive RFfunctionality including the antenna swiches, RF balun, power amplifier, low noisereceive amplifier, filters, power management, and advanced calibratiom ciacuitriesthat allow the solution to dynamically adjust itself to adapt to externalcircuit implefections. For instance, in a low-power IoT sensor hubapplication scenario, ESP32 is woken up periodically and only.
