During January 2026, Santos Vivos developed expanded hardware compatibility for the meshtastic/firmware repository, focusing on enabling LilyGO T-Beam 1W support for long-range deployments. He implemented ESP32-S3 board definitions, integrated RF fan control, and introduced configurable power amplifier ramp timing to optimize performance and reliability. His work included low-level programming in C++ and Arduino, with careful attention to hardware interfacing such as RF switch and LNA controls, as well as TX gain adjustments for 1W operation. All changes were delivered through a single, well-documented pull request, demonstrating depth in embedded systems engineering and collaborative development practices.
