The ESP32 features 802.11 b/g/n Wi-Fi and Bluetooth 4.2 BR/EDR + BLE connectivity.

Espressif Systems’ ESP32 solution

Espressif Systems is the company behind the low-cost and popular ESP8266 Wi-Fi module that enabled hobbyists and developers to connect devices to Wi-Fi networks back in 2014. The ESP32 module, released in September 2016, is the successor to that module, and it offers more in the way of CPU speed, memory, connectivity, and security capabilities. This module offers:

  • Xtensa dual-core CPU
  • 802.11 b/g/n Wi-Fi and Bluetooth 4.2 BR/EDR + BLE capability
  • A host of peripheral interfaces
  • Secure boot
  • Flash encryption
  • Cryptographic hardware acceleration
  • Power management capabilities

The ESP32 makes for a very decent starting point for your next IoT project, and DornerWorks knows how to make the ESP32 work for you.

Use the ESP32 for your Internet of Things

One of our customers came to us for help to design and connect one of their original connected appliances in a rapidly growing market. We understood their concerns and helped them launch the necessary updates as quickly as possible. Finding a design partner that could handle various technical requirements as well as the means to build a testable prototype was crucial to their project’s success, and now they have trusted us with a whole line of their consumer-aligned products.

You might be wondering what makes the ESP32 the right choice for a low-cost proof-of-concept. For starters, development kits featuring this microcontroller exist in abundance, and can typically be found for $15 or less. In addition, the manufacturer provides a development framework that is free to use and easy to reference, making it easy to get a kit up and running with a simple program. The microcontroller provides many capabilities to potentially tap into, making it a great choice for all sorts of projects.

If you’re weighing your options for your next IoT project specifically, the ESP32 will not disappoint.
