In this article we describe briefly the ESP32 chip from Espressif
This lower power SOC contains a 32 bit MCU with bluetooth and wifi modules. At the Espressif web site we can find the detailed informations about the ESP32
The device datasheet is available in the following pdf document
The ESP32 modules are available individually or in a development kits; the last system simplifies its usage as the development kit contains all the hardware to use rapidly the soc device; we are already ready to load the firmware and use the device.
On internet various web sites describe home automation or iot projects using this soc.
A reference site for the ESP32 is
At above link we can find the various development platforms utilized for the ESP32. The most relevant are
- Arduino Ide
- Firmware Lua
We can buy the ESP32 modules/dev kits from various internet online websites, for example ebay
Different ESP32 modules are available from different vendors
At the link
different hardware configurations available are listed.
As development kits we report
There are development kits based on esp32 that also integrate a LORA wireless module internally
We report for example the following
In the next articles we’ll describe how to build firmwares and use the ESP32 MCU.
