This board provides two programmable timer-based pyro channels with tilt limits.

The IMU used is the same as on TeleMega and EasyMega, allowing acceleration based launch detection, and gyro-based tilt limiting. This means it's possible to configure a pyro event for some amount of time after launch, or after motor burnout, etc, with the possibility of locking out each event if the rocket is tilted too far away from vertical.

For projects that require staging or air starts, EasyTimer is a low-cost alternative to use of our more expensive products, while retaining the safety aspects of tilt-limiting.

There is no EasyTimer firmware yet, but it will be part of the AltOS suite eventually.

Prototypes of v1 are underway. This design is not yet for sale.
