About the Project ATO / Supervision PCB

Project ATO / Supervision is an open source PCB design by pratham-cloud-ctrl, published on GitHub under the Custom license license. It is a 4-layer board measuring 300 × 250 mm, with 479 components from 79 distinct parts.

Other key parts include the TMUX7412FRRPR, TPS3700DDCR, OPA391DCKR, SN74LVC1G17DBVR and TPS3431SDRBR. By type, the board carries 160 capacitors, 155 ICs, 134 resistors, 26 connectors and 4 diodes.

From the project

A digital spinal cord-computer interface concept: research, eight KiCad boards, nRF5340 firmware and FreeCAD assemblies.

Complete within the bounded digital reference scope — 16 October 2026. All eight genuinely routed native boards pass DRC with zero violations, unconnected items, schematic parity issues or ignored checks. The independent pad/net audit passes 14,273 assertions. The 80-sheet master passes ERC and 9,540 independent electrical-integration assertions.

Start with the board index and explicit launchers. The Stage 4 exit review records what this package establishes and the remaining physical and biological evidence limits.
