Tram baseboard is an open-source printed circuit board by dg1vs, from the dg1vs/Transputer-Base-Board repository on GitHub, published under the GPL-3.0 licence. It is a 4-layer board of 160 × 100 mm with 32 parts on 116 nets, routed with 187 tracks and 12 vias.
It is built around the SN74LVC1G06DBV, SN74LVC1G04DBV and SN74LVC2GU04DBV. Its parts include 10 resistors, 5 connectors, 4 ICs, 1 capacitor and 1 diode. It belongs with the computers and single-board computers boards of this library.
This project is a 4-TRAM Transputer Base-Board. TRAMs are small subassemblies of transputers (or other components with INMOS links), a few discrete components, and sometimes some RAM and/or application specific circuitry with a standard pinout. This base-board is a compact carrier board for up to four Transputer TRAM modules, arranged as a linear processing pipeline. The board provides the mechanical sockets, power distribution, clock generation, reset/analyse/error service wiring, and Transputer serial link routing required to operate four TRAMs as an ordered chain. The intended module order follows the pipeline ideas, that means
PipeHead → Slot 0 → Slot 1 → Slot 2 → Slot 3 → PipeTail
The external host or upstream Transputer network connects to PipeHead, entering the first TRAM in Slot 0.

This project integrates hardware, firmware, and design elements to develop a fully functional autonomous 3D mapping drone system.
It measures 160 × 100 mm and has 4 copper layers, 1.6 mm thick.
32 parts, built around the SN74LVC1G06DBV, SN74LVC1G04DBV and SN74LVC2GU04DBV. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the dg1vs/Transputer-Base-Board repository on GitHub, at the commit this page was made from: the board is tram_baseboard/tram_baseboard.kicad_pcb and its schematic backplane/backplane.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
