To Drive a 12V LED strip from an Arduino/MCU

This Board has NOT been tested

dual-PMOD to 24bit DVI color using TFP410 PHY from TI.

Just a simple board to wire rgb from the encoder(of models of cdi consoles with the cxa1145 encoder)to your choice of connector(preferably an 8 pin mini din). To be used with a pass through scart cable with no components inside. The positive side of all the caps should be facing the resistors, the negative side of the caps should face the output pads.

MCP1702 SOT89 breakout with JST connectors, see project page for more information.

A companion board for Tim Worthingtons nesrgb mod. This board is made to be soldered on top of an 8 pin mini din pcb mount connector which is soldered into the rf slot of an Nes frontloader for an easy no cut plastic rgb mod. Cover bottom except mounting holes and pins. Use an md 80sm mini din from mouser or digikey or similar uxcell version from amazon.

Same components used as my other cdi board just incorporates an 8 pin mini din. Made to be soldered into the rf space of a cdi 220 console. First, desolder the rf box. Then solder on components and din to the pcb, then flush cut and tape bottom. Then solder capacitor or resistor legs from bottom of the motherboard through the rf slots through top of motherboard. Then place pcb over top of the legs, align board, solder in, and flushcut the legs. Can use an md 80sm din from digikey or mouser or uxcell from Amazon. Install wiring guide at retro rgb .com

Nano-TPDD2 SD Card Drive

It can either be used as a TPDD2 emulation PCB for the Tandy Model 100/102/200.

Highlights:

• Uses Micro-SD card supports up to 16GB.
• Uses an Alkaline AA battery, a AAA battery could be used
• Supports the TS-DOS100/200 protocols.
• Uses FatFS for SD-Card operations
• Supports multiple boot options.
• Can support a bootloader if so desired, updating from SD-Card on request.

It should be capable of supporting the NEC machines but not tested.

The firmware is still being tested if you want a copy to test etc. please contact me.

As yet there is no enclosure for the board but a 3D printed design would be easy to generate for those interested.

Materials

Digikey Parts list

The parts list is provided in Digikey format as an almost complete kit, however other suppliers might have lower prices. Some parts need to be sourced from other suppliers.

Note: The parts lists in some cases includes more than is required for one board this is due to the lower overall price for a larger quantity.
In addition a copy of Atmel Studio 7 (free download) and the Atmel ICE is required to program the on board ATMega part.
