About the SAIHub-Mini PCB

SAIHub-Mini is an open source PCB design by xqe2011, published on GitHub under the MIT license. It is a 2-layer board measuring 48 × 28 mm, with 51 components from 29 distinct parts.

Other key parts include the USBLC6-2SC6, SGM6232YPS8G/TR, ESPC5-32E-H4, TPS2553DDBVR and TPD4E05U06DQAR. By type, the board carries 17 capacitors, 16 resistors, 8 ICs, 3 diodes, 2 connectors and 1 transistor.

It belongs with the test & measurement designs in this gallery.

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…
