Overview

Pu-18 is an open-source printed circuit board by xyzz, from the xyzz/pu-18 repository on GitHub, published under the CC0-1.0 licence. It is a 2-layer board of 191.5 × 136.5 mm with 554 parts on 823 nets, routed with 11,509 tracks and 2,104 vias.

It is built around the DTC114E, 2SA1037AK and 2SC1623, with the 2SB624 and 2SD1781KR among its other parts. Its parts include 186 resistors, 182 capacitors, 33 diodes, 15 transistors and 4 ICs.

pu-18

PCB thickness is 1.2mm. To generate production files you should use KiKit.

What's tested working:

  • Power supplies
  • Digital logic (CPU, GPU, RAM, SPU, etc)
  • Composite video output
  • Memory cards/controllers
  • CD subsystem, audio CD playback, loading games etc
  • Parallel port

Not working / known issues:

  • The holes for the lid switch connector are too small, requires grinding the pins down to fit
  • QFP100 footprints do not extend past the legs at all for Sony chips, making it very difficult to solder with an iron; hot air is recommended

Not tested:

  • Serial port

With the currently defined production setup this is the list of components you would have to transplant from a donor board. These are all located in the same spots on a real PU-18 board so they should be easy to match:

  • CN103: PIO port
  • CN104: Serial port
  • CN502: audio/video multiconnector port
  • IC102: BIOS ROM
  • IC103: CPU CXD8606Q
  • IC106, IC107, IC108, IC109: 4x RAM KM48V514BJ or compatible
  • IC201: VRAM D481850DF or compatible
  • IC202: RGB digital to analog MC141685 or compatible
  • IC203: GPU CXD8561BQ
  • IC303: SRAM CXK5V8257BTM or compatible
  • IC304: Mechacon MC68HC05G6
  • IC305: CDROM decoder CXD1815Q
  • IC308: SPU CXD2925Q
  • IC310: SPU-RAM MB814260 or compatible
  • IC402: Audio DAC AK4309A
  • IC501: RGB to composite CXA1645M
  • IC601: Voltage regulator TA78M05F or compatible
  • IC701: CD DSP CXD2545Q
  • IC703: RF amplifier CXA1791N
  • IC704: Motor driver BA6392FP
  • IC706: uPC5023GR
  • RV703: push-pull adjustment pot, or replace with modern TC33X-1-473E and recalibrate
  • S301: CD cover lid switch
  • X101: CPU crystal
  • X201: GPU crystal

Additionally these are included in the BOM but might need to be transplanted if assembly runs out of stock:

  • IC702: opamp NJM2904
  • IC708: opamp NJM2100

Questions

How big is the Pu-18 PCB?

It measures 191.5 × 136.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Pu-18 use?

554 parts, built around the DTC114E, 2SA1037AK, 2SC1623 and 2SB624. 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.

Where can I download the Pu-18 KiCad files?

From the xyzz/pu-18 repository on GitHub, at the commit this page was made from: the board is pu-18.kicad_pcb and its schematic pu-18.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Pu-18 design in my own project?

Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
