ESP RainMaker Neo is a new implementation of ESP RainMaker in which the entire device-to-cloud-to-app stack, including the cloud backend, is open source under the Apache License 2.0. This article explains what Neo is, why we rebuilt RainMaker on native AWS IoT services, what open source means in practice for your product, and how Neo relates to ESP RainMaker Classic.

Connecting an ESP32 to a cloud platform usually means HTTP libraries, JSON parsers, and TLS handshakes. This tutorial shows a different approach: a single UDP datagram, built with snprintf, carrying structured sensor data in about 130 bytes. The TagoTiP open specification makes it possible by defining the data structure so you don’t have to.
