Do you want HDMI output from your Amiga 500 / 500+ without using a crappy RGB to HDMI converter or expensive OSSC?

Please be aware that this is for the Amiga 500 / 500+ only. It will not work on the Amiga 600 or Amiga 1200.

We have the answer with this Amiga RGB to HDMI CPLD adapter powered by the humble Raspberry PiZero.

NOTE that this is for the long version of the RGB board. For most cases, you should check out the normal one which we hold more stock of here

Amiga RGB to HDMI CPLD PiZero Adapter – Amiga 500 / Amiga 500+

Updated CPLD board design

This updated CPLD board design by Linux Jedi (affectionately known as long boi*) offers a number of advantages over the previous model

  • Stops sparkling effects due to timing issues on the previous designs
  • Support for Terrible Fire cards – this extra long boi has been designed to allow the use of the TF536 with the relocator. See photos for more info.
  • Support for PiStorm (relocates the Pi allowing both devices to be fitted)

How does it work?

The RGBtoHDMI interface converts the “digital” RGB video signal from vintage computers like the BBC Micro or PC MDA/CGA/EGA to HDMI or DVI compatible with most modern TVs/Monitors. The interface comprises a Raspberry Pi Zero and a specially designed Hat containing a small CPLD. Custom firmware on the Raspberry Pi, in conjunction with the CPLD, is able to correctly sample each of the supported video modes to give a pixel-perfect rendition. The HDMI output is locked to the input so there are no frame drops, repeats or tears and it also has low lag of around 4 milliseconds (less than a quarter of a frame).

Please note that the HDMI output DOES NOT carry audio. You will still need to use the audio outputs on the rear of the Amiga.

What do I need

If you are just ordering the adapter you will need the following items

1 x Raspberry PiZero (with headers)
1 x MicroSD card compatible with the Raspberry PiZero
1 x Mini HDMI cable to HDMI cable

You do not need a power supply for the PiZero. Power is supplied through the GPIO pins that attach to the Amiga.

What does it include

1 x Amiga RGB to HDMI PiZero Adapter – fully tested
1 x Email instruction on installation and use
1 x Control button / switch

We now offer the adapter and a pre-installed tested SD card. You will need to supply your own Pi Zero.

1 x Amiga RGB to HDMI CPLD PiZero Adapter
