New version built
eZ80 for RC2014™ and compatible backplanes
An eZ80 CPU Module that works within the RC2014™ ecosystem
21 Jul 2024
I have achieved some success since my self inflicted RTC issue.
I built a new eZ80 CPU module paired with a newly designed Bus interface module. The new interface module has solved some critical compatibility issues I was having.
I seem to be getting better at hand soldering the SMD component. The eZ80 pins are quite tiny - and my hands do shake quite a bit - but I got there.
Some images of the assembling
I start by assembling the CPU module, soldering all the SMD components first. The resistors and capacitors are easy. The eZ80 is a little tricky. Once its done, I double check I don’t have any shorts.
The partially assembled eZ80 CPU module. Just need to finish soldering some of the remaining PCB pins. (had to use a 470 ohm through-hole resistor as I did not have a SMD version on hand)
As the PCB pins are quite small, I use the interface PCB to align a few pin.
Then I can insert the CPU module and solder them. Repeating this for a small set of pins, until all are done.
And the underside of the module, with all the pins finally soldered. Only need to solder the ZDI 6 pin header.
The completed solution - ready for testing.
