About the Flight computer PCB

Flight computer is an open source PCB design by unl-rocketry, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 27 × 60 mm, with 32 components from 19 distinct parts.

Other key parts include the CPC1002N, BME280, BNO055 and TPS62172DSG. By type, the board carries 11 resistors, 7 connectors, 6 ICs, 3 capacitors, 2 diodes and 1 crystal.

It belongs with the sensors and robotics & motion designs in this gallery.

From the project

An experimental flight controller/altimeter board family developed by UNL Aerospace Rocketry

All designs in this repository are licensed under the CERN-OHL-S v2 or any later version. Contributions are welcome!

The connectors on the Core Board are compatible with any Adafruit Stemma QT or SparkFun Qwiic board, which immediately provides for a lot of options for sensors without any design or soldering work needed.

In the future, this repository will host the KiCad files for expansion boards created by UNL Aerospace Rocketry.
