ESP-WROOM-32
Introduction:
1. ESP32 is a single-chip solution that integrates 2.4 GHz Wi-Fi and Bluetooth-compatible 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.
