About the Project ATO / Current Driver PCB

Project ATO / Current Driver 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 175 × 155 mm, with 156 components from 33 distinct parts.

Other key parts include the DAC80502DRXR, OPA192IDBVR, TMUX7212PWR, TMUX6219DGKR and LTC6993HS6-1#TRPBF. By type, the board carries 57 capacitors, 51 ICs, 39 resistors, 7 connectors and 2 transistors.

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.
