The Super Synth Projects 40 x 2 character OLED module used in our kits operates on 5 volt supply, consumes very little current at 15mA and is generally compatible with other manufacturers of displays that have LED, EL or no backlight.
It has a US2011 controller IC that is almost compatible with the Hitachi HD44780 display controller. It has a slightly faster response time when dealing with commands. There are many displays it can replace from manufacturers including: Hitatchi, OKI, Winstar, Seiko, Sharp.
It has been tested with and known to be electrically compatible with the following instruments:
- Roland D50 & D550, JD-800
- Yamaha DX7IIFD, DX5, TX-802
- Korg M1
- Oberheim MC2000
If you wish to buy this display for an instrument not listed above, there is no guarantee that it will work despite connectivity being the same. There are slight differences in the software commands for user defined characters and timing.
Mounting
OLED module has exposed flexi cables that are fragile, take care not to knock these or fit
the display into a position where they could be rubbed against metal work etc.
Before fitting, confirm that metal work and fixing points do not foul or touch any of the
components on the underside or “flexi cable” of new OLED PCB, nor should the metalwork touch any trace.
In many cases when spacing or attaching, nylon washers need to be used to prevent short circuits to pins 1, 2, 15 & 16 of the OLED module.
The pictures below highlight in red show the potential areas of concern when fitting the
display.
Back Light Connections
This display does not require separate back light power and doesn’t have
connections for it. Pre-existing connections have to be left unconnected or removed.
Pins 15 and 16 on OLED PCB can be ignored, they are not used.
ESD Handling Precautions
If this is supplied by us it is fully tested and shipped in ESD packaging. Firstly a layer of conductive bubble wrap or foam followed by an ESD shielding bag to prevent induced ESD discharge damage occurring outside of the packaging.
When working on an instrument or handling any electronic display, it is necessary to keep ESD under control using conductive mat and wrist band.
They can be purchased from eBay for very little money. Many electronic parts in old instruments are no longer available, taking anti-static precautions reduces the possibility of damage or weakening of old semiconductors thus causing unreliability or unusual operation.
