+The ARM7-based 'AltusMetrum' design has been shelved indefinitely.
Working with Keith Packard, I recently embarked on a complete redesign based on the TI cc1111.
We got there by deciding we need a low-power RF beacon for post-landing direction finding, learning
of the existence of this part, then realizing that we could radically simplify things by using it

It looks like we can get all the features we want on a single board for less than the price of most
commercial altimeter boards, with the only downside being dramatically reduced processing power.
