Wow thanks for all the advice everyone!
Do you have a battery connected? I'm not sure if it could cause your problem but I remember reading a comment further back about the polarity markings being reversed on the battery leads - remove the battery and trouble shoot with only hard wire connection.
You probably did, but make sure your are holding down the escape key when you plug the board in all the way through to when it finishes flashing (I think you can let go once flashing begins but I can't remember off the top of my head).
Lastly, check the solder connections on the PCB and daughter board (the controller and usb port especially) and ensure the plug between daughter board and PCB is firmly in place.
That's all I can think to check.
Edit: did you test the board before building and/or flashing a hex file?

I made sure the polarity on the battery connector was correct and I have tried it both with and without the battery plugged in.
I Looked over all of my solder points and saw no issues. I made sure all the diodes and resistors looked good as well and it seems so. I will double check the USB/daughter board.
I tested to be sure it connected and lit up and all was well. Beyond that I'm not totally sure how best to test a PCB before building.
The BT PCB doesn’t have those solder points that are on the standard pcb. There is no qmk port for the BT PCB yet.
Unfortunately qmk hasn't been ported to the bt pcb.
And it may not be until BT support is expanded in QMK. It will really depend on what BT module is used on the pcb and whether or not it’s supported in QMK currently.
Good to know, thank you.
I'm hoping to get some help with flashing the BT PCB. I've reached out to Barry and he got to me quickly but we haven't come up with a solution.
When I try to flash my BT PCB using a CAD66 hex file generated on ydkb.io and flashed using ydkb-reflash tool I get a "Reflash Complete" output (see image). However the keyboard is inoperable and I get a device disconnect tone repeatedly until I unplug the PCB. I have noticed that the YDKB website is wonky to say the least and I am concerned that I am not generating a proper hex file. I'm curious if anyone has had similar issues or has any advice for me here.
I've read through the thread and tried everything with the exception of trying to use QMK. I do not see the solder points people are referring to regarding QMK. Any help is appreciated.
Thank you in advance!
The size of your downloaded firmware is not correct.
here is mine.

I think this is my issue. Barry mentioned the same thing. I'm not sure why that would be though. I've had all sorts of trouble on ydkb.io trying to create a keymap. When I use CAD66 the image will be of whatever keyboard was selected before it not of a CA66. When I switch layers it reverts changes on all layers but the default Layer0. Also when I first select CAD66 the default key mapping is crazy. All keys are set to obscure macros. Perhaps I should try a different browser?
Again thanks for the awesome feedback everyone!
