esp32

The ESP32 has finally become widely available at sub-$10 price points — time to get one and put it to work.

A note on board selection: The Geekcreit ESP32 development board is quite wide. When placed on a breadboard, only one row of pins remains accessible on each side. For the pins on the far side, jumper wires need to be routed underneath the board.

Cloud connectivity with Mongoose OS

For a quick path to the cloud, Mongoose OS is an excellent choice. The firmware flashing and configuration process is remarkably straightforward — the ESP32 can be set up and connected to AWS IoT within minutes.

Key highlights:

  • Simple provisioning — Flash, configure WiFi, connect
  • AWS IoT integration — Mongoose OS handles certificate generation and device registration automatically
  • OTA updates — Built-in over-the-air firmware update support for deploying changes to devices in the field
  • End-to-end encryption — TLS communication out of the box, securing data in transit between device and cloud
  • Rapid prototyping — From unboxing to cloud-connected device in under 10 minutes (with an existing AWS IoT account)

A solid starting point for anyone exploring ESP32-based IoT architectures with AWS.
