120 mAh Battery

These are very slim, extremely light weight batteries based on  Polymer Lithium Ion chemistry.  Each cell outputs a nominal 3.7V at 120mAh.  Comes terminated with a standard 2-pin JST connector - 2mm spacing between pins, that plugs directly into the battery connector on Altus Metrum flight computers. These batteries are approximately 4x15x30mm, and weigh 3.6g. These batteries are ideal for use with TeleMini in airframes as small as 18mm. Dual deploy in an Estes rocket, anyone?. WAR…

1600 PSI Pressure Sensor

0-1600 psi pressure sensor, with "Buick" style connector and analog output.   These sensors take 5V DC in and give an analog voltage out that ranges from 0.5 volts at 0 psi to 4.5 volts at the full scale of 1600 psi.  The sensor body is stainless steel, and the input fitting is a male boss threaded 1/8 inch NPT.  These sensors are ideal for use in high power rocket motor characterization, and directly connect to our motor characterization boards.

400 mAh Battery

These are very slim, extremely light weight batteries based on  Polymer Lithium Ion chemistry.  Each cell outputs a nominal 3.7V at 400mAh.  Comes terminated with a standard 2-pin JST connector - 2mm spacing between pins, that plugs directly into the battery connector on Altus Metrum flight computers. These batteries are approximately 0.2x1.0x1.4" (5.5x25x35mm), and weigh about 9.5g (0.33oz).  This battery is very close to the size of a TeleGPS board, would provide about 12 hours of r…

850 mAh Battery

These are very slim, extremely light weight batteries based on  Polymer Lithium Ion chemistry.  Each cell outputs a nominal 3.7V at 850mAh.  Comes terminated with a standard 2-pin JST connector - 2mm spacing between pins, that plugs directly into the battery connector on Altus Metrum flight computers. These batteries are approximately 0.25x1.2x2.0" (6x30x48mm), and weigh about 19g (0.67oz). Note that while we sell these as 850mAh cells, our supplier varies their process from time to ti…

Easy Mini

This is a small, baro-only recording dual-deploy altimeter for model rocketry Features User View Recording altimeter for model rocketry Supports dual deployment (can fire 2 ejection charges) Barometric pressure sensor good to 100k feet MSL Designed to use a battery supplying 3.7V-12V. 1.5 x 0.8 inch board designed to fit inside 24mm airframe coupler tube 1MB on-board data logging flash Weighs only 6.5g (less than 1/4 oz) Developer View Hardware Features S…

Easy Motor

EasyMotor is designed for in-flight characterization of research rocket motors. It records chamber pressure and acceleration to an on-board flash memory chip, the contents of which can be downloaded after flight over USB.  

EasyMega

User View Recording altimeter for high power model rocketry Supports dual deployment and 4 additional pyro events. Pyro events are configurable and can be based on time and various flight events and status, including angle from vertical (for safety in staging and air start flights). Barometric pressure sensor good to 100k feet MSL 3-axis 200-g accelerometer for motor characterization 3-axis 16-g accelerometer for gyro calibration 3-axis 2000 deg/sec gyros 3-axis magnetic sens…

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…
