SNES Digital Audio with CS8406-CSZ and PLT133

by borti4938.

2 layer board of 0.95x1.12 inches (24.13x28.42 mm).
Shared on October 16th, 2015 09:03.

This is just another shape of the Dig.Audio Mod incl. TOSLINK jack. This one should also fit into the SNES mini/jr.

Parts needed: Audio Jack: PLT133/T10W, IC: CS8406-CSZ (SOIC-28), C1-C3: 0.1uF (0805)

SNES-LED logo base

2 layer board of 0.64x0.89 inches (16.21x22.71 mm).

Idea and ATTiny-Code by jensma @ circuit-board.de http://circuit-board.de/forum/index.php/Thread/7573-Super-Nintendo-Beleuchtetes-animiertes-Logo/

Last change: I moved resistors for the LEDs to the PCB of the LEDs.

Parts needed:
- 4x 1kOhm (0805 package)
- 4x 2N2222 (SOT23 package)
- 1x 100nF/50V (0805 package)
- 1x ATTiny45-20SU (SOIC-8 package)

Code for the ATTiny45: http://circuit-board.de/forum/index.php/Attachment/529-sneslogo-attiny45-zip/
Fuses:
- low: 0xe2
- high: 0xdf

PCB has to be soldered to the Expansion port.
/RST is to reinitiate the logo animation. Either close the jumper (animation on every system reset) or connect the pad with the CIC-lock pin10 (animation only on user reset). NEVER do both!!!

SNES-LED-Logo

by borti4938.

2 layer board of 0.90x0.88 inches (22.89x22.23 mm).
Shared on August 26th, 2015 11:31.

Last changes: Move resistors for LEDs to the LED-PCB. LEDs in 0805 package or P-LCC-2 package can be used.

Parts needed:
- 4x resistors (values according the LEDs used, 0805 or P-LCC-2 package)
- 4x LEDs in red, green, yellow and blue

Install the PCB directly below the SNES logo. Drill holes in advance. More information needed:

SNES multi region mod [now tested]

by borti4938.

2 layer board of 1.71x1.28 inches (43.36x32.41 mm).
Shared on January 7th, 2015 19:10.

Includes SuperCIC, uIGR and Regionpatching. The part of regionpatching is new designed!

Solder Joints:
- Most of the solder joints are located at the cart connector as to be seen on the silkscreen.
- The mode output located at the PCBs bottom right side is goin' to the
- S-CPUN Pin 111
- S-PPU1 Pin 24 and S-PPU2 Pin 30
- One may use the additional pad for the add-on PCB for the 1Chip-SNES or to use separate wires to S-PPU1 and S-PPU2
- CIC8 and CIC10 has to be solder to the pads, not the the lifted pins
- Reset input can be solder directly to the reset buttons output instead of CIC8
- ‘Contr. Port’ means the connector for the flat wire. In the SNES-mini the mapping is as follows:
- 10 -> Player1 Pin3
- 8 -> Player1 Pin2
- 6 -> Player1 Pin4


Lifted Pins:
- S-CPUN Pin 111 OR S-PPU1 Pin 24 and S-PPU2 Pin 30
- CIC Pins 1, 2, 10 and 11 OR remove CIC completely


Values of passive components:
R1, R2: 220Ohm (increase resistor values if LED is too bright)
R3: 10kOhm
C1 - C5: 0.1uF


Active ICs (SOIC14 packages):
74*27: three 3-NOR gates, where two are unused
74*30: 8-NAND gate 74HC(T)125: four buffer gate: use HC or HCT type!

S-CIC: PIC16F630 flashed with ‘Firmware_SCIC.hex’
uIGR (V2): PIC16F684 flashed with ‘Firmware_uIGR_V2.hex’
Both firmwares can be found at https://github.com/borti4938/SNES-AddOn-PCBs/tree/master/Firmware-Switchless-PICs
!!!Note that the ‘snes-igr.hex’ in the sd2snes github repository, i.e., the ‘classical igr’ won’t work on this PCB!!!
