When using the I2C with just Power LED & R1 installed, the I2C is fails.
You must install C2, even without the 7805 installed.

As I was stripping my 3rd party Nunchuk extension cable I noticed it doesn't
conform to the standard Nintendo wire colors (and has a couple of unused wires
too). Maybe the controller PCB's silk could be revised to read Data, Clock,
+3.3V, GND to avoid confusion?

Restart housing design with a clean state.
Overall bulk of wristmount needs to be reduced. Wristmount needs to be
adjustable to any forearm size
Some design considerations...
- wristmount could house touchscreen only; arduino, controller shield and batteries to be housed in remote enclosure (possibly clipped to belt)
- touchscreen could be mounted to inner wrist (opposite of a typical watch location)
- wristmount should be easily secured using only one free hand

RSeries I2C is +5V vs NXP standard of 3v3.
The NXP standard, like the NunChuck connector is 3v3 VDC.
However to power the I2C FX Modules, we used 5VDC so that one 4 wire cable can
do both the I2C and the power to the other Arduino UNO.
Currently there is no plans to move this to 3v3 volts. If you need to interface
a 3v3 I2C device, please consider using AdaFruit's $3.95 4-channel I2C-safe

The LCD's backlight LEDs are supposedly controllable by PWM. To conserve power,
would it be difficult to get the sketch to go into 'power saver mode' and dim
those down after 30 seconds or so of no touchscreen activity? And maybe have it
shut off entirely if no input from the touchscreen or nunchuk is heard for a
set time?
I'd think the most troublesome part would be coding the sketch for it to 'wake
up' on the next touch instead of making an input.

What steps will reproduce the problem?
1. rMP3 uses D6 & D7 for SoftwareSerial control
2. D6 is co assigned to Servo S3
3. D7 is also co assigned to Logic 7219/7221
We can readjust the pin assignments to support 6 servos, Logic & rMP3 usage
concurrently.
For example 13, 12, 11 for Teeces logics, D6 to Servo 6, which would still
force a limitation of only being able to use 5 servos when using rMP3 as well.
The PCB will work as designed, it just might be better at some future date to
update, it just doesn't give us the potential flexibility it could have.

The current design of the receiver shield has several connection points for
servos, but using the current 5V to power servos you'll only get 2-3 servos
working before overload/overheating.
Couldn't the power for the servos has it's own power regulator/feed on the same
board or should there be a servo power PCB made?
What solutions are people using?

What steps will reproduce the problem?
1. This really should be 4 pins... instead of 3.
2. Should match v5 of FX I2C Module
3.

C1 & C2 Footprint needs to be tighter as well as need to add Negative lead

I2C FX Shield v4 - 7805 Output only connected to 5v Header Pin and needs to be
fixed.
Current solution would be to jumper header ping to 5v bus, which is about 10
mils away.

To make powering the controller a little easier, would it be possible to add
two JST sockets to the PCB? That way two Lithium Ion batteries could be hooked
up.
Two 1000mAh batteries would give us enough play time, right?
I'm looking at these...

The batteries would have to be removed for charging, so having the connectors
close to an edge of the PCB might make connecting and disconnecting easy.
