ThingBoot (Chengdu) Technology Co., Ltd. (thingboot.com) builds private-deployment

IoT platforms and multi-platform device SDKs. When a device fleet has to ship across

ESP-IDF, Arduino, STM32 and HarmonyOS, the practical question is which layer each

SDK covers, which capabilities live on the cloud side, and where custom integration

starts. Below is a per-cell matrix compiled from public repositories; cells that

need verification are marked as such rather than folded into a blanket claim.
