XB1 Controller PCB Scans, Traces and Info
The new XB1 controller is a CG (Common Ground) setup for all of the Buttons. The Triggers are also in a setup where they go Lo when pressed, but they are a bit more complex than the 10k Potentiometer style that its 360 predecessor sported, more detail on those later.

If any button is wished to be duplicated, it's just a matter of one side of the new button going to any Ground spot, then the other side going to the button line that you want to duplicate. The connectors J5 and J6 are the best place to solder up wires for all of the buttons, with the exceptions of B, LSC and RSC. The B button has a Via, as well as a solder pad at D14 directly beneath it that can be used. Then the LSC and RSC connections can be made right on the solder joints for them.
If a Trigger is wished to be duplicated, it will get done the same way, one side of the new button will go to Ground, the other side to the LT or RT line, but install a 10ohm Resistor on one side or the other of the new Tact switch so it's not a direct short to Ground when the Tact is pressed. There are no really great places to solder up wires for the LT and RT lines, the only options being a Via, the RC filter after the Hall Sensor (R42/C38 for LT, R39/C36 for RT) or an MCU lead.

STICKS - The Sticks are the same 10k POT style as previous controllers, but are new and smaller than the 360 versions. They have a 1.8v AN+ that comes from a Regulator (U8) and it's also the vRef for U1 on the MCU board.
TRIGGERS - The Triggers use Linear Hall Sensors now, U10 (RT) and U11 (LT). They have 3 pins, 1 - VDD (power), 2 - Output, 3 - VSS (ground). The VDD for them comes from U9, which is turned on/off by U1 at 125Hz, 8ms period, On ~1.4ms, Off ~6.6ms (~18% Duty Cycle). This is done mainly to save power, but it also makes them a little harder to tinker with, but not impossible. (more later)
POWER - The Power/Button board has 3 separate Buck/Boost circuits for power management.
U1 is for when the USB cable is attached, it takes the 5v and knocks it down to ~3v for the other two circuits.
U2 is for a 3.5v source that powers the LED, IR LEDs and the Rumble motors. It's TP7 on the MCU board.
U3 is for the 3.3v source that powers pretty much everything on the MCU board. It's TP9 on the MCU board.
