NES Power / Output Module 'Bucky v1.3'
 
NESRGB Companion Board
 
New NES frontloader power / RGB output connector module with plug for nesrgb connections for use with the nesrgb mod. Molex connector for the nes motherboard making it completely detachable.
 
Modern switched mode buck converter regular circuit.
Almost twice as power efficient as the 7805 linear circuit.
Generates a lot less heat with no need for a heatsink.
 
Integrated RGB multi-out connector. This is the neatest way to rgb mod the frontloader model nes with no need to mount a seperate output connector.
 
Switch to select audio source, either nesrgb or original nes motherboard audio.
 
2 output connector options:
 
Option 1: Multi out connector for use with snes rgb scarts (ntsc)
(Ideal for rad2x, ossc, retrotink and other scalers)
 
Option 2: Mini DIN9 connector for use with megadrive 2 / genesis 2 rgb scarts (Compatible with 1080p scalers for HDTV's that I sell here)
 
Some minor filing / cutting to the case is necessary for both output connectors.
 
Power Input Specification: 9V DC 1-2 Amp center negative 2.1mm
 
This is for use with a DC adapter centre negative! Not compatible with AC, like the original AC nintendo adapter. I have decent DC adapters available here
 
Assembly Notes:
 
Cut the composite video trace on the nes motherboard and link to ground. This is the trace going to the end pin of original module. See photo.
 
Min DIN9 connector:
 
If using the Mini DIN9 option with a Genesis 2/ Megadrive 2 Scart, the RGB wires need to be soldered near the KA2198 chip on the nesrgb board (see photo). This is because there are capacitors and resistors already present within the scart on the RGB lines.
 
Multi out connector:
 
Place fingerboard / middleboard in multi connector before soldering to get the plate spacing correct. See photos.
 
Supplied in kit form, some assembly required.
