Developed by Espressif Systems, the ESP32 series brought a revolution in the electronics industry. Also widely known as “the chip of the future”, it saves you from a lot of programming complexity and can be easily connected with almost any device you want to build. Now you only need to use this device instead of the complex system consisting of a micro-controller, add-on WiFi, and Bluetooth modules.

ESP32 is a series of the low power system on a chip (SoC) micro-controllers. What makes ESP32 series better than its predecessors is that it comes integrated with WiFi, BLE, and dual-mode Bluetooth. Other than cost-effectiveness, the ESP32 devices promise security, performance, and energy efficiency to the modern IoT devices. It is integrated with built-in antenna switches, power amplifiers, filters, power management modules, and RF balun. Thus, make it easier for you to build any modern IoT device with convenience and minimum budget.

Features & Specifications of ESP32

  •  ESP32 has the Dual Core Processor, which means an external microcontroller would not be required for building connected things. It comes equipped with Xtensa® Dual-Core 32-bit LX6 microprocessors. ESP32 series operate at 160 or 240 MHz and runs up to 600 DMIPS. It has ultra-low power (ULP) processor and comes with a memory of 520 KiB SRAM. 
  • The majority of the ESP32 Modules have inbuilt filter capacitors, onboard antenna, and metal shield for EMI protection. 
  • It supports a power supply of 2V to 3V and operating temperature that ranges between - 40ﹾC and -140ﹾC.  
  •  The external flash memory can be extended up to 16 MB.  
  • If used in station (client) mode, ESP32 can be connected to most of the WiFi routers. It also works on WiFi Direct. 
  •  It implements TCP & UDP and allows five simultaneous connections at a time. 
  •  It supports both classic Bluetooth and the latest BLE Bluetooth 4.2.
  •  ESP32 comes equipped with multiple built-in peripherals that include a touch sensor, digital to analog converter (DAC), ADC and built-in sensors, Pulse Width Modulation (PWM), real-time clock and a lot more. 
  • The device comes packed in 48 pin QFN packages with varying sizes.
  •  ESP32 modules are available with multiple antenna configurations like PCB antenna, antenna connector, etc. as well as flash sizes. 
  •  It comes with a fully compliant four-layer robust design to be used with FCC, IC, KCC,TELEC, CE-RED, SRRC, etc. 
  •  The USP of ESP32 series is its software/firmware that allows you to use freeRTOS to handle multitasking hassle freely. 
  •  It also offers security features like flash encryption, integrated AES, secure boot, SHA & RSA algorithms.
