ESP-WROOM-32E WiFi Bluetooth Development Board, Dual Core CPU, Serial Port Module

The core of this module is the ESP32 chip, which is scalable and self-adaptive. The clock frequency can be adjusted from 80 MHz to 240 MHz, and it supports RTOS. It is a general-purpose Wi-Fi + Bluetooth + BLE microcontroller unit (MCU) module. The NodeMCU-32S module integrates classic Bluetooth, Bluetooth Low Energy (BLE), and Wi-Fi. It supports various applications: Wi-Fi enables broad communication connectivity and direct internet access via routers; Bluetooth allows connection to mobile devices or broadcasting BLE beacons for signal detection. The module supports a data transmission rate of up to 150 Mbps, and the antenna output power reaches 20 dBm, enabling long-range wireless communication.
