ESP32 Hardware
ESP32 is a cost effective, less power consumed SOC (system on a chip)
microcontroller which is integrated with Wi-Fi and dual-mode Bluetooth
devices. This series utilizes “Tensilica Xtensa LX6” microprocessor which
works in both the dual-core and single-core variations. It involves the
following in-built modules: antenna switches, RF balun, power-amplifier, low-
noise receive amplifier, filters, and power-management modules. This
hardware is designed by Espressif systems, a Chinese company. It is an
inheritor of ESP8266 microcontroller. It is very convenient to be used with IoT
projects because of the open source platforms like Arduino.
ESP32 Module
The ESP32 development board includes Tensilica Xtensa® Dual-Core 32-bit
LX6 microprocessor (lastminutesengineers 2019). Unlike ESP8266, this
processor contains two individually controlled CPU core processors operable
at adjustable clock frequency ranges from 80 to 240 MHz and performs
operation at a speed of 600 DMIPS (Dhrystone Million Instructions per
Second).
The main components present in the module are as below:
a) Xtensa® Dual-Core 32-bit LX6: Operates at high speed to fed up real
time information
b) Memory blocks: Both for programming and storage data, it provides
enough space to cope with large string data used by IoT devices.
i. 448kB ROM
ii. 520kB internal SRAM
iii. 4MB external flash
c) 802.11b/g/n Wi-Fi transceiver: This module includes different
compatible versions of Wi-Fi transceiver which allows other devices to
connect directly with it by setting up a personal network. It uses WiFi
Direct technology where peer-to-peer connection can be established
without the use of an access points. It is very easy to setup and the
data transmission rate is better than the Bluetooth technology.
d) Bluetooth 4.2/BLE: The module also contains dual mode Bluetooth
devices, which supports both Bluetooth 4.0 (BLE/Bluetooth Smart) and
Bluetooth Classic (BT). This makes the device even more versatile.
Power Requirements
MicroB USB connector is used to provide power to the ESP32 development
board. Otherwise a 5V regulated voltage source may also be connected to
