About the Adafruit BMP390 PCB

Adafruit BMP390 is an open source PCB design by Olin-Rocketry, published on GitHub. It is a 2-layer board measuring 21.6 × 14 mm, with 21 components from 18 distinct parts.

Other key parts include the BMP388 and BNO055. By type, the board carries 7 ICs, 4 resistors, 3 capacitors, 2 diodes, 1 transistor and 1 jumper.

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).
