+### User View ###
+
+* Recording altimeter for high power model rocketry
+* Supports dual deployment and 4 additional pyro events.
+ Pyro events are
+ configurable and can be based on time and various flight events and status,
+ including angle from vertical (for safety in staging and air start flights).
+* Barometric pressure sensor good to 100k feet MSL
+* 1-axis 105-g accelerometer for motor characterization
+* 3-axis 16-g accelerometer for gyro calibration
+* 3-axis 2000 deg/sec gyros
+* 3-axis magnetic sensor
+* On-board non-volatile memory for flight data storage
+* USB for power, configuration, and data recovery
+* Integrated support for LiPo rechargeable batteries
+* User choice of pyro battery configuration, can use primary LiPo or any
+ customer-chosen separate pyro battery up to 12 volts nominal.
+* 2.25 x 1.25 inch board designed to fit inside 38mm airframe coupler tube
