All,
I pushed an updated version up to GitHub today.
Spent the better part of the day working the parts list. Have identified mfg part numbers for all parts now. Put that list into Mouser and found a couple of issues I am still working on. Two parts are not in stock or have minimum buys. I will fix these tomorrow then post the parts list here.
Looks like we need about $350 per board in parts not counting the TMS570 and the AX5043. These last two are not on the list because they are not available at Mouser and we already have inventory on these at AMSAT I hope.
I made the heat sink pad on the AX5043 smaller to be sure it would not be an issue.
I added some circuitry to take care of powering down for the Transmitter when things go bad. Actually added a second watchdog chip for this. I figure we need the processor running on its own so we could upload code and commands if the transmitter is stuck in an effort to recover.
I did a few other smaller task like renamed parts on the PCB and made minor changes in schematic. Will post updated PDF of these tomorrow.
