Spin Semiconductor

Thanks, those are both helpful, and what I expected regarding failure rate. I did source the ICs in China (i live there) and lesson learned... One batch I received are 2008!!! Definitely will get better organized and use only the approved suppliers.. it's an expensive mistake!! I certainly wouldn't ...

What's a good way to test FV-1 chips to make sure they are working before soldering them in? I'm still new to building, and finding some of mine aren't working despite voltages etc all being correct. Maybe it's due to too much heat, or possibly a questionable batch of ICs I bought recently, but it w...

Try it now, I've updated the permissions on the images... Sorry, I haven't used S3 for a while and they lock down things differently...

The eeprom switching will be done using one selector so when for example program '0' is selected both FV-1's will receive there own (different) code from there respective Eeprom. Did you ever get this working? I made a board which does this (one rotary switches two FV-1s, but it only switches four ...
