Description:
ESP32 is already integrated antenna and RF balun, power amplifier, low-noise amplifiers, filters,
and power management module. The entire solution takes up the least amount of printed circuit board area.
This board is used with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips by TSMC 40nm low power technology,
power and RF properties best, which is safe, reliable, and scalable to a variety of applications.
Using TSMC low power 40nm technology, power consumption performance and RF performance are the best, safe and reliable, and easy to expand to various applications.
ESP32 is designed for mobile, wearable electronics, and Internet of Things (IoT) applications. It has many features of the state-of-the-art low power chips, including fine resolution clock gating, power modes, and dynamic power 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 is also adjustable to achieve an optimal trade-off between communication range, data rate, and power consumption.
