This co-processor board allows you to use a RaspberryPi Zero or Zero 2 Single Board Computer, as an offload for various tasks in your Amiga with a clock port. It has been tested to work in an Amiga 1200, and could also work with other devices that expose a clock port. In such case, You may need to adapt the Amiga-side driver yourself for this to work. See the open source repository at https://github.com/niklasekstrom/a314/tree/clockport_if or the A314 discord for more information. The PCB for sale here, is an alternative design, which can be found at the forked repo https://github.com/Eriond/clockport_pi_interface/.

A 40-pin female header for the Raspberry Pi is included with the board, but not soldered on. The header is for those of you that wish to keep your Raspberry SBC removable. If you need help with the soldering of this header, please let me know along with your declaration of interest, and I'll do it for you. Note that if you choose to have a header soldered on to the board, the complete module won't be as low-profile as shown in the photo above.

Attention:

Important note 1
This PCB is designed to be mounted back-to-back with the RPi Zero/Zero2 ! If you own a RPi Zero or Zero2 with a pin header already soldered on, it's likely that the header is mounted on the top, or component side. That configuration won't work with this version of the A314-cp, as the RPi will then attach upside-down to what is intended, and sensitive pins on both boards will end up cross-connected, leading to possible damage of the A314-cp, RPi Zero and/or your Amiga!
If you're unsure of how to relocate the pin header yourself, take help and advise from someone who has the skills and knowledge. Don't risk damaging your Amiga.
Important note 2
To ensure proper operation of this adapter and the attached SBC, you need to make sure the PSU that is powering your Amiga, has it's voltages within specs and is in good working order. Old PSUs are known to have degraded outputs, and may cause disturbances and other hard-to-identify issues for the A314-cp adapter.

Further questions and comments are welcome at the A314 discord.

Asking €39 + €13 for worldwide tracked shipping = Total €52

With soldered header, please. :)

Also, out of curiosity.. any idea if this would work with a clockport expander in order to have both a freeway USB and a314-cp in an A1200?

Thank you for your interest!
There have been a lot of progress lately in the area of using this device with clockports (and expanders) other than the "standard" port in an A1200. I will however need to refer you to the A314 Discord for more information and the actual state of matter right now. (See first post for links)

Soldered mine together with an old rpi zero 1.1 w. Don't have a way to get software into my Amiga just yet, so haven't tried anything yet.

Digging in to where to fetch a .img file so I can write it to an SD card...

1) Yes, the board's CPLD is updatable via a JTAG connection from the attached RPi. That is how I program and test each board that is shipped out.
2) Having the form factor it has, I assume that most if not all, users are using it with a Zero or Zero 2. However, since the 40-pin GPIO connector is kind of "universal" with the exception of the very first Raspberry Pi (having a 26-pin connector), I guess it would work as long as there aren't any physical obstructions in your Amiga. I can't vouch for using extension cables with the GPIO header, since they may affect signal integrity in a negative way.

4) Nobody said Amiga hardware should be particulary cheap. This is an exception however. I make about €6 of each board sold. I spend apx. 1½ hour per board, taking into account the PCB design, component sourcing, soldering, packaging and shipping and handling. Not even accounting for all the tooling I need to have, or the wear of said tools. So... I guess the steep price is a matter of opinion.
Very Interested!
 
Got my card last week and finally got it connected, I have to say Eriond and the guys on the A314 Discord channel were a massive help and if anyone else is having trouble setting theirs up, the Discord channel should be your first stop.

Declaring interest in one unit, shipped to Norway.
