Features

  • 1. ESP32 is a single-chip solution that integrates 2.4 GHz Wi-Fi and Bluetooth dual-mode, using TSMC's ultra-low-power 40-nm process.Optimal power performance, RF performance, stability, versatility and reliability for a wide range of applications and different power requirements.
  • 2. ESP32 is designed for mobile devices, wearable electronics and Internet of Things (IoT) applications. As the industry's leading low power chip, ESP32 has Fine-resolution features such as clock gating, power-saving modes, and dynamic voltage scaling.For example, in a low-power IoT sensor Hub application scenario, ESP32 will only be periodically woken up under certain conditions. Low duty cycle can make
  • 3. The energy consumption of the ESP32 chip reaches a small value. The output power of the RF power amplifier can also be adjusted to achieve the most balanced communication distance, data rate and power consumption.
  • 4. ESP32 is designed for mobile devices, wearable electronics and Internet of Things (IoT) applications. As the industry's leading low power chip, ESP32 has Fine-resolution features such as clock gating, power-saving modes, and dynamic voltage scaling.
  • 5. The energy consumption of the ESP32 chip reaches a small value. The output power of the RF power amplifier can also be adjusted to achieve a balance between communication distance, data rate and power consumption.
