About the BMI088 PCB

BMI088 is an open source NXP PCB design by Olin-Rocketry, published on GitHub. It is a 2-layer board measuring 29.2 × 18 mm, with 13 components from 7 distinct parts.

Its main chip is the TEENSY3.6, from the NXP family. Other key parts include the BNO055 and MPL3115A2. By type, the board carries 8 resistors, 3 ICs and 2 capacitors.

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).

BMI088: common questions

What microcontroller does the BMI088 use?

The BMI088 is built around the TEENSY3.6, from the NXP family.

How big is the BMI088 PCB?

The BMI088 measures 29.2 × 18 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BMI088?

13 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 BMI088 design files?

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

Can I use the BMI088 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.

Can I test firmware for the BMI088 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
