4 This board provides two programmable timer-based pyro channels with tilt
5 limits. It is the same size and shape with the same connector layout as
6 our [EasyMini](../EasyMini) flight computer, and will sell for the same
9 The IMU used is the same as on TeleMega and EasyMega, allowing acceleration
10 based launch detection, and gyro-based tilt limiting. This means it's
11 possible to configure a pyro event for some amount of time after launch,
12 or after motor burnout, etc, with the possibility of locking out each event
13 if the rocket is tilted too far away from vertical.
15 For projects that require staging or air starts, EasyTimer is a low-cost
16 alternative to use of our more expensive products, while retaining the safety
17 aspects of tilt-limiting.
19 EasyTimer firmware is part of the [AltOS](../AltOS) suite.
21 Prototypes of v1 work great, and our first production run is now
22 underway. If all goes well, we hope to have these for sale sometime
29 * Two programmable flight state event and timer-based pyro channels with
31 * USB for configuration
32 * Designed for use with batteries from 3.7 to 12 volts
33 * 1.5 x 0.8 inch board
37 This board was designed using lepton-eda and pcb-rnd.
