NNCpro
AKA NoNameComputer 2.0
Built for sky.
NNCpro is a fligth computer designed mainly for rockets but it also can be used for other vehicles.
It is designed to collect data from all of the sensor, sending it IRL back down to the earth via radio link, deploy parachutes, steer rocket in flight using aerodynamic control or TVC and at the end send live location.
We have designed it for our rockets because there is no comercial computers or if there is something it's very expensive. We actually like designig electronics and thats why we're even here.
Features
8x Servo outputs (PWM channels)
6x Pyrotechniacal channels (used for firing parachute charges, motor ignitions etc.)
Long-Range radio (based on two LoRa modules for simultaneous transmiting and reciveing)
Current and Voltage sensing (based on INA3221 three channel current sensor)
Audio signaling (using passive buzzer with possibility of modulation sound wave)
Flash memory for storing software and flight data in flight
micro-SD card slot for saving fligth data after landing
3,3v and 5v power supply
ARGB LEDs for signaling computer states

Questions
How big is the NNCpro PCB?
It measures 40 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the NNCpro use?
263 parts, built around the E220-400M22S, MAX-M10M-20B, NC7WZ07P6X and BMP390L. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the NNCpro KiCad files?
From the PlanAndBuild/NoNameComputer-2.0 repository on GitHub, at the commit this page was made from: the board is Board/NNCpro.kicad_pcb and its schematic Board/Igniters.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NNCpro design in my own project?
Its repository states no licence, so its author keeps all rights: ask PlanAndBuild before reusing the design.
