ESP32-powered 4-inch touchscreen builds a TUI dashboard for monitoring a DGX inference cluster
CATLLM · reddit · 2026-11-02
Reddit user CATLLM turned a $-cheap 4" ESP32 touchscreen from AliExpress into a btop-style TUI dashboard for monitoring a DGX inference cluster, showing throughput, TTFT, prefill/decode tok/s, KV cache, context tokens and cache-hit stats. Firmware is built with PlatformIO on the Arduino-ESP32 core and open-sourced at dicksondickson/system-d-monitor; a SKILL.md is included so you can point your coding agent at it to compile for you. A 3D-printed dock is in the works.
