Introducing the ESP32
First, to get started,
what is an ESP32
? The ESP32 is a series of chip microcontrollers developed by Espressif.
Why are they so popular? Mainly because of the following features:
Low-cost
: you can get an ESP32 starting at $6, which makes it easily accessible to the general public;
Low-power
: the ESP32 consumes very little power compared with other microcontrollers, and it supports low-power mode states like
deep sleep
to save power;
Wi-Fi capabilities
: the ESP32 can easily connect to a Wi-Fi network to connect to the internet (station mode), or create its own Wi-Fi wireless network (
access point mode
) so other devices can connect to it—this is essential for IoT and Home Automation projects—you can have multiple devices communicating with each other using their Wi-Fi capabilities;
Bluetooth
: the ESP32 supports
Bluetooth classic
and
Bluetooth Low Energy (BLE)
—which is useful for a wide variety of IoT applications;
Dual-core
: most ESP32 are dual-core— they come with 2 Xtensa 32-bit LX6 microprocessors: core 0 and core 1.
Rich peripheral input/output interface
—the ESP32 supports a wide variety of input (read data from the outside world) and output (to send commands/signals to the outside world) peripherals like
capacitive touch
,
ADCs
, DACs, UART,
SPI
,
I2C
,
PWM
