NES Power / Output Module 'Bucky v1.3'
NESRGB Companion Board.
RGB SNES Multi-Out or Megadrive 2 Genesis 2 RGB Output !
HDMI output using this scaler (with the MD2 option)
New NES frontloader power and RGB output connector module with plug for nesrgb connections. For use with the NESRGB upgrade kit. 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 these SNES RGB Scarts
Option 2: Mini DIN9 connector for use with megadrive 2 / genesis 2 RGB scarts and HDMI output using this scaler
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.
How to remove the original power module
Remove the solder from the 4 long tabs, use a desoldering gun in combination with an soldering iron or solder wick, flex the joints so they are loose. (see 2nd last photo)
Flip the board, clamp in a vise then just heat the row of 5 pins with a soldering iron and pull nes mb away, some low melt solder with a long angled chisel tip will make this easier. (see last photo) I sell low melt solder here
I plug these in and test them before sending
