Control Panel Adapter (Rev. 2)

Control Panel Adapter (Rev.2) for do-it-yourself arcade projects.

Vision Most do-it-yourself arcade projects are utilizing the so-called Neo Geo control port standard. The Neo Geo control port has many advantages: The signals are not encoded and hence easily accessible via discrete wires. Also, the D-sub DA-15 sockets and plugs are freely available. Regardless of those advantages, one may lose focus when dealing with all those signal wires for joysticks and buttons. Moreover, ground wires may be needed in various places when dealing with microswitches whereas the Neo Geo port only delivers a single ground wire.

Solution We have been developing a small PCB (printed circuit board) which distributes the wiring of a Neo Geo controller port in a convenient and accessible way for any do-it-yourself project. On top of that - we have taken one more bold design-step forward and now provide extra terminals to integrate LED illumination for buttons and joysticks.

Benefit The Control Panel Adapter can be connected to any Neo Geo compatible arcade controller port (MVS or AES game consoles or even compatible MAK/Supergun ports). All input ports are clearly labeled - no more mixed up connections! Small wires from microswitch wiring can be soldered directly to the round pads (with holes!) on the adapter.
On top of that, there is also a set of 10 additional soldering pads in the center of the PCB. These optional soldering pads are usually connected to each other only and hence isolated to the rest of the PCB. However, by soldering a small bridge, you will be able to configure these additional pads either as ground or as 5 volts power drawn from the Neo Geo controller port. Thanks to this flexibility, you can use the optional pads to power a set of small LEDs for button illumination for example without the need of an external power source. On request, we can even integrate a DC-converter in order to power 12 volts LEDs. However, a maximum of 2 watts power draw should not be exceeded from a single controller port.

  1. designed for do-it-yourself control panels, supporting one joystick, 4 buttons, start and coin/select for one player
  2. all signals are labeled - no more mixed-up signal wires
  3. connects to any Neo-Geo MVS/AES mainboard or our JAMMA Supergun/MAK Interface via D-sub 15-pin cable (not included)
  4. 10 signal pads and 10 ground pads for easy soldering
  5. group of 10 configurable pads (group isolated, ground or 5 volts) which can be used for LED illumination

This picture illustrates the signal pads' labels. Ground lines are on the top and signal lines are on the bottom layer of this professional two-layer PCB.

Features Despite its small form factor, one single Control Panel Adapter supports one player for arcade gaming. Here is a feature overview.

  1. shielded D-sub DA-15 female connector output (Neo Geo MVS compatible)
  2. soldering pads (holes) for joystick directions (up, down, right, left) and four action buttons plus start and coin in (select)
  3. 10 soldering pads (holes) for ground connections
  4. group of 10 soldering pads (holes) configurable as isolated, ground or 5 volts; max. 2 watts of power draw
  5. recommended wire diameter 0,5mm
  6. red status LED for the Sub-D 15-pin port

Do-it-yourself even easier -
Control Panel Adapter with Terminal Screws (Rev.2)

Control Panel Adapter with terminal screws

Benefit Connect external wiring from microswitches easily to the 20 terminal screws without soldering! The Control Panel Adapter can be connected to any Neo Geo compatible arcade controller port (MVS or AES game consoles or even compatible MAK/Supergun ports). All input ports are clearly labeled - no more mixed up connections!
Important - this Terminal Screw version does not support the 10 optional soldering pads for LED illumination but there is one single soldering pad which provides access to the 5 volts supply from the control port!

  1. shielded D-sub DA-15 female connector output (Neo Geo MVS compatible)
  2. terminal screws for joystick directions (up, down, right, left) and four actionbuttons plus start and coin in (select)
  3. 10 terminal screws for ground connections
  4. two optional soldering pads (holes) for ground connection and 5 volts connection from the control port
  5. one optional soldering pad (hole) for ground connection from control port
  6. one optional soldering pad (hole) for 5 volts connection from control port
  7. recommended wire diameter 0,5 - 1,5mm (terminal screws only)
  8. red status LED for the D-sub DA-15 port

We are offering our remaining Control Panel Adapter with Terminal Screws (Rev.2) on a first-come, first-serve basis for 25,- € each (incl. VAT) (excluding packaging and postal fees, ask for details, please).

All boards are tested and working flawlessly. For questions, please refer to us via email. This is a private sale, so no returns or refunds, sorry.

Control Panel Adapter - Special Options

Special requests only - Control Panel Adapter with microswitch wiring

Microswitch Wiring We can even customize a Control Panel Adapter for you; including the complete wiring for attaching microswitches. Here is a good example which consists of 10 ground and 10 signal wires including 6,3mm microswitch terminal plugs.

12V DC Converter In some rare cases, an LED illumination may require 12V of voltage. We can even support these special applications by integrating a 12V DC converter. The DC converter will output 12V to the 10 optional soldering (center) pads. Hence, even 12V LEDs can be powered directly without the need for an additional power supply. However, the total power consumption of all LEDs must not exceed 2 watts (or max. 168mA current draw respectively). Note: The 12V DC converter does not support any 12V lightbulbs since the current draw and power consumption is far too high!

Other variants may also be possible on special request, assuming that we have the necessary parts still in stock. Please ask for details via email ofni.regit-repap@ybbob

Sample Project

Our readers know already that we make heavy use of tradiitonal microswitches for our own arcade tables. Hence, our custom-made PCBs simplify the electrical wiring of these projects to a great extent. No more mixed-up buttons and joystick directions thanks to the individually labeled terminals.

Sample wiring: The button and joystick microswitches (on the right) are connected to a Control Panel Adapter (center) which is connected to one of our JAMMA interface PCBs (left).

Sample wiring: The button and joystick microswitches (on the right) are connected via individual lines to a Control Panel Adapter (center) which is connected to one of our JAMMA interface PCBs (left) via flatwire.

The small Control Panel Adapter connects to the microswitches from buttons and joystick.

D-sub DA-15 Reference

D-sub DA-15 connectors need to comply with the Neo Geo MVS/AES standardD-sub DA-15 connectors need to comply with the Neo Geo MVS/AES standard We have been carefully designing the DA-15 port pin assignment on our Control Panel Adapter and JAMMA Interfaces to match the Neo Geo MVS/AES standard. Even pins 4 and 9 are both connected to button no. 4, which has always been a Neo Geo oddity.

Pin Name JAMMA Standard
1 Ground GND
2 not connected not connected
3 Select Coin in
4 D Button Button 4
5 B Button Button 2
6 Right Right
7 Down Down
8 +5V +5V
