About the MiniAvionics PCB

MiniAvionics is an open source PCB design by Olin-Rocketry, published on GitHub. It is a 2-layer board measuring 12.9 × 11.1 mm, with 8 components from 7 distinct parts.

Other key parts include the BNO055. By type, the board carries 3 resistors, 2 capacitors, 1 IC and 1 connector.

It belongs with the rf & radio, sensors and power & battery designs in this gallery.

From the project

Sensing hardware and software

Repository for all Olin Rocketry hardware and firmware.

The purpose of the avionics system is to determine when to deploy the drogue and main chutes, and to send the signal to do so to the recovery system. The flight computer contains several sensors to help detect apogee, and a microcontroller to read and process the data and send the signal.

- a commercial-off-the-shelf (COTS) flight computer; - a student-designed flight computer, which includes sensors, microcontroller, GPS, and radio; and - a student-designed battery management system (BMS).

MiniAvionics: common questions

How big is the MiniAvionics PCB?

The MiniAvionics measures 12.9 × 11.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MiniAvionics?

8 components, from 7 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the MiniAvionics design files?

From the Olin-Rocketry/sensing repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the MiniAvionics design in my own project?

The repository has no license, so all rights stay with Olin-Rocketry. Use it as a reference, and ask the author before reusing the design.
