Great news guys. Both the boards I designed worked on the first revision

woot!
There was a bit of a scare when neither the controller or the receiver worked after initial flashing with my 1+year old hex file, but it turns out flashing a hex file compiled for a different part number MCU doesn't tend to work out so well *facepalm*
Luckily the source compiled with no complaints on the cheaper and smaller chip I am using now.
Unfortunately, it seems the coin cell out of my old prototype controller has bitten the dust. I would have expected much longer standby time than a year but who knows what might have happened as it has been sitting in a big messy parts box and I originally pulled the coin cell out of a wii that could have came from 2006 for all I know.
I plan to re-run all the numbers on power consumption anyways to verify everything is okay. After that I'll make a few changes to the board to increase manufacturability and then put in an order for probably around 100 boards. I think I am going to just go with having 2 different frequencies hard coded into the firmware and give the option for purchasing one or the other.
Until then I have 2 boards left that I haven't assembled that can be used for testing purposes. I will probably keep one to verify 2 players at the same time works well but the other is up for grabs with KalessinDB having called initial dibs.
