NOTE: This is a presale item£¬ all the orders will be shipped out on April£¬ 25th probably. Overview: 1. 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. 2. ESP32 is a highly integrated solution with less than 10 external components. 3. ESP32 integrates the transmit /receive RF functionality including the antenna switches£¬RF banal£¬power amplifier£¬ low noise receive amplifier£¬filters£¬power management£¬and advanced calibration circuitries that allow the solution to dynamically adjust itself to adapt to external circuit inflections. 4. The entire solution reduces Printed Circuit Board (PCB) area£¬time-to-market£¬and bill-of-material(BOM)costs while adding capabilities and processing power.the mass production of ESP32 does not require expensive and specialized Wi-Fi test equipment. 5. ESP32’s ultra low power consumption radio architecture and proprietary power save technologies extend batter life in real-world applications£¬using the following features:a. Fine granularity clock-gating b. Multiple low-power modes c. Dynamic voltage scaling For instance£¬in a low-power IoT sensor hub application scenario£¬ESP32 is woken up periodically and only when a specified condition is detected;low duty cycle is used to minimize the amount of energy that the chip expends.The output power of the power amplifier can also be adjusted£¬so that an optimal trade off between the communication range£¬data rate and power consumption is achieved.
