Do you think we're going to need a latex parser plugin here? OFC we do :-) Use latex bb-tags.
Adapter's for following functionalityes could be kind:
-i2c - so you can add your own i2c harware
-gps can be used to controll frequency generato, to get ^8 accurancy for tranceiver it self and other application,... this idea also need's most likely changes to current frequency source,... this could be optional piece of hardware !
I2C - sure, we can add it, but we certainly won't use GPS module for frequency stabilization.
