Description

This is a very basic PCB to put a Raspberry Pi Zero into an old sinclair spectrum 48k case... Code is by a Mr P J Evans and is called ZX Scanner on Github, I've basically made a PCB of his work and added my own hardware parts!

There's a footprint for an RTC this will use generic Pi RTC code There's a footprint for an Adafruit I2S amplifier board...i've only put this in for those that want to run composite video AND have audio for the pi

After manufacturing this MK1 version, i've found there are some very minor alignment issues - none of which affect the use of the boards I had made, however, will be corrected in MK2

1 - The Composite output socket sticks out too far....needs to be moved 'in' a little 2 - I got the Ear and Toggle the wrong way round 3 - The Toggle right angled switch needs to move to the left 1/2mm AND it needs to be about 1CM long...or, move the whole footprint up a little so it sticks out further from the case 4 - The top hole for the screw is about 1/2mm too low 5 - the side screw holes are tight - they snap into a genuine case perfectly...Need to make them a little larger for a production run

Enhancements to follow in MK2 1 - Arduino mode - footprint included to allow use as a USB keyboard OR a Pi zero keyboard 2 - On Board Regulator for 6-12V power 3 - Better alignment 4 - Footprints for SMT devices OR through Hole 5 - Miscellaneous additions as I figure uses for the spare Arduino I/O and Pi GPIO
