# TelePyro
This is an 8-channel pyro expansion board for [TeleMetrum](../TeleMetrum/).

## Motivation ##
It would be nice to support more than the 2 channels of igniter control
included in the stock [TeleMetrum](../TeleMetrum/) design, so that we can
fly more complex projects involving staging, air starts, and backup ejection
-charges. We also want to experiment with better circuits for testing igniter
-continuity, with the hope of being able to measure actual resistance and not
-just continuity.
