ESP32
Ladybug starter
Most teams install the whole starter as a library instead — see setup. These single files are for repairing a broken copy.
Open the complete starter repository →Reference release · ESP32 Arduino 3.3.7
Take it to the bench.
The starter examples compile with PubSubClient 2.8, DHT sensor library 1.4.6, and ESP32Servo 3.0.9. Team credentials are issued separately and never belong in Git.
Trust
Garden Spine CA
ESP32 teams do not need this. The certificate ships inside the library as spine_ca.h, and the helper verifies every connection with it.
Download it for the Python publisher, which reads it from disk, or to check it against the copy in the library. Never replace either with insecure mode.
