ESP32

 

The ESP32 is a 32-bit microcontroller manufactured by Espressif Syetems. It is an upgrade to the popular ESP8266 and features integrated WiFi, Bluetooth and BLE.   It is available in a number of popular modules and is the perfect microcontroler for IoT debvices and designs that require IoT and Internet access.

The ESP32 can be programmed using several different programming environments and using several programming languages, including micro Python and C++.  It is a 3.3-volt device that is capable of operating in an ultra-low-power mode, making it ideal for battery-powered applications. Many ESP32 modules have an integrated battery charger and connector for a 3.7-volt Lipo battery.

Some ESP32 modules have additional integrated perhephials, including displays, microSD card sockets and even cameras.

The ESP32 is a low-cost device that can be the bbasis for very powerful designs.

Getting started with the ESP32-CAM

Today we will look at the amazing ESP32-CAM module from A-Thinker. This 10-dollar module features a 2MP camera, microSD card socket, WiFi, and Bluetooth.

Unlike other ESP32 modules this one does not have a USB port, so you'll need to use an FTDI adapter to get it working.

In this article I'll show you how to work with the ESP32-CAM and how to resolve common power and antenna issues.
