Where is this list?

Add some fold out legs and you have a docking station in the same unit. It's
certainly neater than an octopus cable, or multiple adapters.
In another post I suggested putting the 3G module, gps, pressure and ambient
light sensors, magnetometer and gyro plus connectors in a small clip on module
using the 40 pin connector. That makes phone and navigation hardware an option
for those that want it without requiring AI to change their existing design,
or force the extra expense on those that don't want it. The moko nav board v2
already shows the sensor circuit - 3.3v supply and i2c interface as available
on the 40pin connector. There's a serial port for GPS too, which just leaves
3G, and perhaps some level shifting for the interfaces.
