Looks like we are good to go if we want to add a non-VEX sensor per the college challenge appendix F.
7. There is NO restriction on sensors and additional electronics used for sensing and processing
except as follows:
a. Sensors & Electronics MUST be connected to the VEX Microcontroller via Analog/Digital
Port or Interrupt Port. They cannot directly interface with the VEX Motors.
b. The additional Sensors & Electronics can only receive power from any of the following:
i. Directly from the VEX Microcontroller via Analog/Digital Port or Interrupt Port.
ii. From an additional VEX 7.2V Robot Battery or from a VEX 9.6V Transmitter
Battery (only one (1) additional battery can be used for sensor power.)
