Analyzer is an open-source printed circuit board by dennowiggle, from the dennowiggle/Retro-PETER repository on GitHub, published under the LGPL-2.1 licence. It is a 4-layer board of 101.6 × 76.2 mm with 62 parts on 184 nets, routed with 1,071 tracks and 246 vias.
It is built around the 74LVCH245APW,118, CC0603KRX7R9BB104 and RC0603FR-0710KL, with the SC-1634(10), RC0603JR-070RL and B320B-13-F(MS) among its other parts. Its parts include 30 capacitors, 9 ICs, 7 resistors, 5 connectors and 1 diode. It belongs with the sensors and measurement boards and the RP2350 boards of this library.
Z8S180 On RCBUS Only.
ZORO is an RCBUS board with a Z180 CPU. There is no RAM or ROM memory hosted on the board.


The 'output' directory contains the BOM, netlist, and PDF schematic.
Board design used KiCad 8.0.4.
Change J2 to Adam Tech part number PH2RA-80-UA to reduce insertion force.

Open-source ESP32-P4 trimix analyzer prototype for technical diving,
It measures 101.6 × 76.2 mm and has 4 copper layers, 1.6 mm thick.
62 parts, built around the 74LVCH245APW,118, CC0603KRX7R9BB104, RC0603FR-0710KL and SC-1634(10). 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 dennowiggle/Retro-PETER repository on GitHub, at the commit this page was made from: the board is Hardware/Analyzer/Analyzer.kicad_pcb and its schematic Hardware/Analyzer/Analyzer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the LGPL-2.1 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
