BBL-B pcb(CONTACT: jmg9137@rit.edu with questions) Jonathan Godfrey

70mm X 40mm

Needs to have:

• Arduino compatible board for easy field reprogramming (Currently using link / Link ) (or: (link))

• 3x Servo ports with 5v

• Baro sensor for alt up to 40KM (link) (Only to 30KM)

• micro SD card logging(open to other options) (link)

• Port for gps module(can just be pads to solder to)(Currently using: (link)) (Use standard header pins)

• Powered off 1s(3.3-4.2v) 18650 batt (link)

• A silly little silkscreen of a smiley face (no)

• get it as small as possible

• button ports (Jumpers)

• temperature, humidity(for logging) (link) (or link)

Nice to have:

• Hot wire cutter

• a screen or a port to plug in one of those silly lil i2c screens (no)

anything not heated / insulated will go to -40, assume -60, heating

try and calculate power loss to determine if the circuit can heat itself
