RGB2HDMI – Amiga Ed.

First of all I must admit that the Amiga community is awesome. In 2020 many new cool projects has been published and many of them are also completely open source. One of they that has got my attention is the RGB2HDMI project where a Raspberry Pi Zero is used to sample analogue RGB signals and convert them to digital HDMI and with minimal latency.

I did not take long time until someone made an adapter that would fit in an Amiga 500/500+, making the installation simpler than ever.

Therefor I decided to make a guide on how to make one of those adapters and also sell 12 of them on Amibay for a good reasonable price.

For this project I ordered ENIG surface PCB from JLCPCB and all other components from Mouser and Electrokit in Sweden.

This guide will now teach you how to solder, tell you what tools to use and how to perform some soldering techniques. That will be covered in another post later.

Flux and put some solder on ONE pad of the SMD passives (capacitors and resistor).

Attach the passives and then solder the other end and do not forget to add more flux.

Trim the legs of the bottom pin header facing away from the RPi Zero header.

Solder the bottom pin header to the PCB and be sure to flow the via with solder.

Solder the OCS/ECS Denise angled pin header to the PCB.

Solder the 48 pin socket for Denise/Super Denise to the PCB.

Solder the 40 pin header for the RPI Zero and also the 2 pin header on the side of the RPi header.

Do not forget to add the jumper/shunt to the 3-pin header where you select between OCS/ECS Denise version. Before you plug it into your beloved Amiga 500/500+, be sure to clean it and check it for shorts since you don’t want to damage your Amiga.

Enjoy!
