New housing for future easier flashing .DB9 is JTAG connections and for pin 55

Very nice and clever.
I saw some people put the pins into the empty pins of the DB-25 parallel port instead.


Ordered a couple new carprogs and I noticed the erase pin of the atmel chip is connected to a wire that leads to an "empty circle" (not sure what it's called). Do not have to lift the processor pin anymore. Just solder to the empty circle.

Yeah you can wire from inside on board to db25 on spare pins then use a wiggler or jlink.
I made an adapted wiggler that has db25 socket on both ends with the 5 resistors you need for a wiggler so just plugs straight in.

The hole on pin 55 track is a via/through hole it connects the top track to the track on otherside of board which goes to ground

On mine pin 55 is lifted and connected to a 3pin jumper header so mcu can be switched between gnd erase flash modes. so dont need to open anymore just connect to computer and 12v then switch jumper for programming mode
