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.
- 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.
