From the project
Give your agent a hand: MIT-licensed ESP32-C5 IO board that speaks MCP, so Cursor, Claude Code & Codex can drive GPIO, PWM, UART and power on real hardware.
Version: 2026-09-24. Author: GPT6-Astra. Co-author: xqe2011.
The date version changes only with explicit user permission. See the version log; regeneration and exports preserve the approved version.
Current state: fully routed and CAD-validated. The updated schematic and PCB include U6/U7 header protection (TPD4E05U06DQAR), U10/C21 power-pin protection, TPS2553DDBVR output switches, and shared MDD SS34 parts for D1/D3. Both output fault nets reach separate controller inputs with test pads retained; R13/R14 are removed. Firmware must enable internal pullups before monitoring faults; that…
