Eggtimer Rocketry Quasar User Manual page 8

Getting to know your Quasar
Although the Quasar seems relatively simple, you will want to familiarize yourself with it
BEFORE you install it in a rocket, and certainly before you try flying it.
Battery (BATT) – Two solder pads for connecting the Quasar's battery. It's not polarized...
you can't hook the battery up the "wrong" way. We recommend a 2S/7.4V LiPo battery, 500
mAH or higher... more on that later.
Buzzer - "Beeps" out status, warnings, apogee at landing, and other important notifications.
Main Deployment (MAIN) - Two solder pads for connecting an electric match or other
deployment device such as a hot-wire or a servo. Deployment altitude can be set from 100' up to
3,000', or it can be turned off if you don't need to use it.
Drogue Deployment (DROG) - Two solder pads for connecting an electric match or other
deployment device such as a hot-wire or a servo. This normally triggers right after nose-over,
but you can delay it from 100 ms to 30 seconds for backup use, or deploying some other device.
You can also turn it off if you're not going to use it.
AUX Channel (AUX) - Two solder pads for connecting an electric match or other on-off
deployment device such as a hot-wire. The AUX channel can be configured as a second Drogue
output, a second Main output, or for Airstart functions, which trigger at a set time after launch.
Programming Cable Header – 3-pin header that's used with an Eggtimer USB-Serial cable for
updating the software or for viewing the WiFi passkey (in case you lose it).
Programming Jumper Pins (PGM) – Two pads used to put the Quasar into programming mode
at boot-up, for uploading software updates. Normally you'll leave this open.
RUN Jumper Pins (RUN) – Jumper pin that connects the GPS output to the processor. This is
normally shunted, except when you're updating the firmware (in which case the shunt goes on
the PGM header).
Servo Header Pads – Pads for connecting servos to your Quasar, they are a logic-level output
instead of a high-current output. Note that power for your servos is NOT provided; you must
provide it separately, and we strongly recommend additional filtering on your external servo
power (more on that later).
OpenLog Header Pads – Pads for connecting an OpenLog datalogger. This streams out the
serial data that goes to the RF radio module, with the standard NMEA GPS data. You can use
the data that the OpenLog saves to get a "track" of your flight using software such as Google
Earth.
