1. NodeMCU-32S IoT Development Board ESP-32S Wifi Development Board WIFI+Bluetooth Main Board Serial Port Module
NodeMCU-32S IoT Development Board ESP-32S Wifi Development Board WIFI+Bluetooth Main Board 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 80MHz to 240MHz, and it supports RTOS. It is a general-purpose Wi-Fi+BT+BLE MCU module. The Nodemcu-32s module integrates traditional Bluetooth, Bluetooth Low Energy and Wi-Fi. It has a wide range of uses: Wi-Fi supports a wide range of communication connections and also supports direct connection to the Internet through routers, while Bluetooth allows users to connect to mobile phones or broadcast BLE Beacon for signal detection. The data transmission rate supported by the module is as high as 150Mbps, and the antenna output power reaches 20dBm, which can realize wide-range wireless communication. Features: 802.11b/g/n 802.11n, speed up to 150Mbps). WIFI frequency range 2400~2483.5MHz. Clock frequency adjustment range 80MHz to 240MHz.
