About the Rev2 PCB

Rev2 is an open source NXP PCB design by Olin-Rocketry, published on GitHub. It is a 2-layer board measuring 72 × 80 mm, with 34 components from 21 distinct parts.

Its main chip is the TEENSY3.6, from the NXP family. Other key parts include the MPL3115A2, ADXL345BCCZ and TPS2113ADRBR. By type, the board carries 12 resistors, 7 diodes, 7 capacitors, 4 ICs, 3 connectors and 1 speaker.

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).

The KiCad project lives in the Olin-Rocketry/sensing repository on GitHub; these links point at the commit this page was built from.

Rev2: common questions

What microcontroller does the Rev2 use?

The Rev2 is built around the TEENSY3.6, from the NXP family.

How big is the Rev2 PCB?

The Rev2 measures 72 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rev2?

34 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 Rev2 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 Rev2 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 Rev2 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.
