- 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 andInternet of Things(IOT) devices. ESP32 integrates all WLAN and BT functionalityin a single package to support a low cost, layout-friendly implementation whileallowing flexibility for platform specific customization.
- ESP32 is a highly integrated solution withless than 10 external components.
- 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.
- The entire solution reduces Printed CircuitBoard (PCB) area,time-to-market, and bill-of-material(BOM)costs while addingcapablities and processing power.the mass production of ESP32 does not requireexpensive and specialized Wi-Fi test equipment.
- ESP32’s uitra low power consumption radioarchiteature and proprietary power save technologies extend batter life inreal-world applications,using the following features:
- Fine granularity clock-gating
- Multiple low-power modes, and
- Dynamic voltage scaling
- For instance, in a low-power IoT sensor hubapplication scenario, ESP32 is woken up periodically and only when a specifiedcondition is detected; low duty cycle is used to minimize the amount of energythat the chip expends. The output power of the power amplifier can also beadjusted, so that an optimal trade off between the communication range, data rateand power consumption is achieved.
