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.
