Built my first functional REX on the castellated PCB. Programs and tests okay.
But, I've also built me second non-functional REX, too. So far I'm 3-out-of-5 for successful builds. Not sure I'm really up to this. :( Maybe I can figure out what's wrong w/ this board. Impact says it finds lots of unknown devices on the chain and barfs. Reflowed the CPLD pins but it didn't help. Bugger. At least I have one functional REX for my 102, so, yay! -Josh On Fri, Oct 20, 2017 at 10:05 PM, Brian White <[email protected]> wrote: > That would be awesome of course! > > On Oct 20, 2017 12:35 PM, "Stephen Adolph" <[email protected]> wrote: >> >> good to hear the castellated board is working. >> I revised the REX PCB design to (1) remove unneeded parts (2) use ground >> and power planes and (3) provide a pad to bridge 3.3V onto PORT_EN with a >> solder bridge.
