About the Rev1 PCB

Rev1 is an open source NXP PCB design by Olin-Rocketry, published on GitHub. It is a 2-layer board measuring 83.8 × 94 mm, with 43 components from 21 distinct parts.

Its main chip is the TEENSY3.6, from the NXP family. Other key parts include the BNO055, MPL3115A2, BMI088 and ADXL345BCCZ. By type, the board carries 13 capacitors, 5 ICs, 5 resistors, 3 connectors, 3 diodes and 1 transistor.

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).

Rev1: common questions

What microcontroller does the Rev1 use?

The Rev1 is built around the TEENSY3.6, from the NXP family.

How big is the Rev1 PCB?

The Rev1 measures 83.8 × 94 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rev1?

43 components, from 21 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 Rev1 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 Rev1 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 Rev1 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.
