  • EasyMega V2

    EasyMega V2

    This is a high-end recording dual-deploy altimeter for high power model rocketry. The feature set is identical to TeleMega, but without the integrated GPS and telemetry link. This makes EasyMega an ideal choice for complex projects including sustainers on multi-stage projects where integrated radio functionality isn't needed. 4 of the 6 pyro events are configurable and can be based on time and various flight events and status, including angle from vertical.

  • EasyTimer

    EasyTimer

    This board provides two programmable timer-based pyro channels with tilt limits. It is the same size and shape with the same connector layout as our EasyMini flight computer, and will sell for the same price. 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 ea…
