Cloud Connector

WiFi, Ethernet, Cellular. Host MCU OTA update

Cloud Connector connects an existing device (product or a proof-of-concept) to the Internet with minimal changes.

Cloud Connector is a pre-built firmware for ESP32. Get an ESP32 module from any distributor, flash a Cloud Connector firmware on it, wire Cloud Connector to your microcontroller, and you're done. Cloud Connector works with any host MCU, starting from a tiny 8-bit AVR up to a powerful 32-bit STM32F7.

Cloud Connector connects simulaneously to mDash to provide device management, and to your own cloud. Cloud Connector can update your device over-the-air without requiring making any changes to your device's firmware on the host MCU.

Cloud Connector is ideal for:
1) Retrofitting devices to make them Internet-connected and updatable,
2) Implementing voice control via Amazon Alexa or Google Home Assistant.
