ESP32 Module: A powerful single-chip solution integrating 2.4 GHz Wi-Fi and Bluetooth. Built with TSMC's ultra-low 40nm process for superior performance, RF capabilities, stability, versatility, and reliability, making it ideal for diverse applications and consumer needs. Designed for Mobility: ESP32 is engineered for mobile devices, wearable electronics, and Internet of Things (IoT) applications. As a leading low-power chip, it features fine-grained clock gating, power-saving modes, and dynamic voltage scaling to minimize energy consumption. For instance, in IoT sensor hub scenarios, ESP32 can wake up periodically under specific conditions. Optimized Power Consumption: The ESP32 chip's power usage is minimized. The RF amplifier's output power is adjustable to balance communication range, data rate, and consumption. Adapter Board: The ESP-32S comes with a matching adapter board with a 2.54mm pitch, exposing RESET and IO0 ports for convenient development and debugging via breadboards or wire connections. Board Size: 36mm x 34mm Color: White Material: PCB + Plastic + Metal Package Contents: 1 x ESP-32S Adapter Board 1 x Wifi Wireless Bluetooth Module (Note: Other products shown are not included. Colors may vary slightly due to lighting and screen differences. Allow for a +/- 1-3cm measurement error.)
