Thank you very much for sharing this. I have a 10-pin Aviator plugs left from another project and was hoping to use them by fitting them inside.
I got a 6P2T switch to switch between the irons.
For some reason, I keep burning the main board
. Seagon were good to send me 2 replacement boards, and I blew both of them. This STC micro is very sensitive to any wrong wiring of the iron. I think the thermocouple pin is connected straight to the pin of the micro and, if not wired correctly, sends 24V straight to it?
I have dead short between the 5V and GND of the Micro pins. When unsoldered the Micro the short is gone. Same on all 3 boards
I think I blew it the first and second times because I did not consider the mirrored pinout between the male and female plugs.
The third time was my last board. I had it working with one side C245 iron through the connection diagram below without connecting the UP/DOWN buttons. The minute I soldered the up/down buttons' yellow and white cables, it beeped like having a cardiac arrest and died on me.
I am completely lost as to what I am wiring wrong. Here is the wiring diagram I got. Can anybody spot an issue with it?
Also, I can't understand why the V+ and V- change polarities between C210 and C245 cartridges? Is that a typo?
Maybe I am that unlucky and should just get Hiroshi plugs and a 4PDT switch and do the extensions outside like you did to avoid any internal foul play.
