Getting to know your Proton
Although the Proton 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 Proton’s battery. It's polarity protected,
so if you hook up the battery backwards it won't damage anything. We recommend a 2S/7.4V
LiPo battery, 300 mAH or higher… more on that later.
Buzzer - “Beeps” out status, warnings, apogee at landing, and other important notifications.
Output Channels (CH1-CH6) - Six sets of deployment output terminals, each with a 10A/40V
capacity.
Battery Output (B+) – Used for the single-battery option when jumpered to the DP+ pad.
Deployment Power (DP+/DP-) – Two solder pads for connecting a separate deployment
battery. If you choose to use the Proton with a single battery for both the computer and the
deployment side, you simply jumper the DP+ pad to the B+ pad, which provides the power for
the deployment channels.
Servo Outputs - Three pads marked "1" through "3", and one labeled "G", for connecting logic-
level servos. These are mirrored to the CH1-CH3 output channels.
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 Pads (PGM) – Two pads used to put the Proton into programming
mode at boot-up, for uploading software updates. Normally you won’t do anything with these
pads.
