AIM USB
From $115Dual-deployment barometric model rocket flight computer with integrated USB
The AIM USB is a dual-deployment altimeter providing flight recording and recovery in one, used in model rocketry. No data kit is required - just connect directly with USB.
The AIM USB is a dual-deployment altimeter: it records your full flight profile and fires both drogue and main recovery charges, all in a compact package that connects directly to a PC over USB.
Its firmware is fully user-upgradable, so your unit can always run the latest version. Free custom software lets you download data, view flights and adjust settings.
Ejection charges are driven by two high-current lines with flexible triggering, timing and redundancy options to suit a wide range of rockets.
Key features

Small form factor: 65 x 25 x 15 mm
Compact enough for narrow airframes and small avionics bays, with a component-free underside for easy mounting.Pressure sensor with 30 cm (1 foot) resolution
The barometric sensor resolves altitude changes down to about 30 cm, giving detailed flight profiles.Integrated temperature sensor
Onboard temperature is logged alongside every flight.Battery input from 3.5 V to 12 V (runs off a single LiPo cell)
Anything from a single 3.5 V LiPo cell to a 12 V pack will power the board.Low current draw (14 mA)
At just 14 mA the AIM USB can wait on the pad for a long time, even on a small battery.Maximum MSL value of 100,000 ft
Records altitudes up to 100,000 ft above mean sea level - plenty of headroom for model rocketry.Two high current (40 amp) ejection lines
Two independent 40 A output lines fire your ejection charges, each with its own trigger settings.Ejection on apogee, time, ascent altitude, descent altitude and peak velocity
Trigger deployment on apogee, elapsed time, ascent or descent altitude, or peak velocity - configured per line.Adjustable line firing time and time delays for redundancy
Firing durations and delays are adjustable, letting you build redundancy between primary and backup charges.Minimum battery voltage alarm settings
Set a minimum battery voltage and the AIM USB warns you before flight if the battery runs low.Least squares apogee detection
Apogee is detected with a least-squares fit over the pressure data, making it robust against noise and transients.Over 30 minutes of total flight time
More than 30 minutes of recording - enough for the whole flight, descent and recovery.Imperial or metric beep-out of altitude after launch
After landing, the altimeter beeps out your apogee in metric or imperial - no PC needed at the field.Data stored at 0.1 second intervals in non-volatile flash memory
Samples are written every 0.1 s to non-volatile flash, so your flight data survives power loss.
