Work with Adsum IoT Coder

Adsum IoT Coder

An AI coding agent for VS Code that works your whole embedded inner loop on Espressif ESP and Nordic nRF.

Adsum IoT Coder is an AI coding agent for VS Code that works your whole embedded inner loop on Espressif ESP and Nordic nRF: scaffold, build, flash, test, observe, fix. It automates the routine firmware work you would rather not do, and cracks the runtime bugs general agents cannot, because it reads your board, not just your code. What makes it different is real human expertise, not just a model. Adsum is augmented with curated firmware knowledge authored by engineers who have shipped, loaded on demand and validated by an open benchmark on real hardware. Human-curated, not AI-generated.

Benchmark

vs Claude Code on the same model, on real hardware.

​
The 30-second proof

vs Claude Code, same model (Claude Haiku 4.5): 5/6 vs 3/6 bugs closed on real nRF hardware, at 3.8× fewer tokens on average and up to 13× on individual tasks. The edge is architecture, not model scale.
