One of the smallest recording altimeters

Tiny: 0.45" x 1.00" (11.4 x 25.4mm)

Only weighs 2.8g (with battery)

Fits into 13mm tubes

Bright red LED

Firmware is field upgradeable by user

Can be used in model rockets, weather
balloons, kites, model airplanes, etc.

Measures up to 100,000 ft. (30.5km) MSL

Resolution is 8" (20cm) at sea level

Very low power: 150µA (average) @ 3V
(depends on sample rate)

Uses readily available CR1220 coin cell
(in battery holder on bottom side)

Records air pressure and temperature

Data compression to increase recording
capacity (typically 2500 samples)

User selectable startup delay, launch detect
altitude, sample rate, etc.

Recorded data is non-volatile, and only erased
when explicitly requested (not from accidental
loss of power due to intermittent connection)

Contest directors will appreciate the tamper-
resistant downloaded data file that includes
byte-for-byte verification of the firmware version

Includes host software for MS Windows; version
for Android planned for future

Conformal coating for protection

4-layer PCB for better EMI immunity

Built-in USB port uses any standard USB Micro-B
cable to communicate to erase, arm, download,
update, etc.

USB port has extra ESD protection to enhance
reliability

Separate USB communication module not required
