ESP-32F WiFi Bluetooth Module

Description:   
ESP-32F WiFi Bluetooth Module is a low power multipurpose wireless development board, which is based on the ESP 32F integrated chip. This module integrates 3 wireless communication modules of the Wi-Fi, Bluetooth, and BLE. Also, The ESP 32 F chip integrates ESP32 SoC, flash memory, accurate discrete components, and a PCB/IPEX antenna. This chip is equipped with 2 CPU cores to achieve stand-alone powering on and self-control. It has an internal 80MHz oscillator for auto-calibration and clock frequency that can be programmed from 80 MHz to 240 MHz.
The WiFi module supports FCC, CE, IC, TELEC, KCC, SRRC, and NCC standards with the protocol of the  802.11 b/g/n/d/e/i/k/r (802.11n, speed up to  150 Mbps) and security mechanism of the WPA, WPA2, WPA2-Enterprise, and WPS. The Bluetooth module supports a protocol that compliant with Bluetooth  v4.2 BR/EDR  and  BLE  standards.  The ESP32 board functions at 2.4GHz frequency band, so it is an ISM radio module, suitable for development with a strong 4-layer FCC, CE ( RED ), IC, TELEC, SRRC & KCC-compatible design in a wide operating temperature range of -40°C to 85°C. These module series are an open-source module, that can be fully customized. The ESP32 series is so designed that can be achieved high RF performance in an ultra-low space module, so is suitable for some projects that have space-constrained such as portable and handheld applications. This development board grants the microcontroller and Arduino board functions to communicate with dual-mode wireless of WiFi and Bluetooth.
