About the Pocket PCB

Pocket is an open source NXP PCB design by kwan3217, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 66 × 38.1 mm, with 31 components from 13 distinct parts.

Its main chip is the Teensy4.1, from the NXP family. Other key parts include the AK09970, P82B96, LSM6DSO and BME280. By type, the board carries 8 resistors, 7 ICs, 7 connectors and 6 capacitors.

It belongs with the sensors designs in this gallery.

KiCad versions of my circuits

Many of my boards have the Open Source Hardware logo on them. Using this logo requires having an open source license and publishing the source. In order to support this, I have the URL of this repository engraved onto the boards themselves.

I have made a release for the Wearable Pocketometer boards, and intend to make a release each time I have a board made.

All boards which have been released since September 2020 have enough information to construct a bill of materials. This is in the form of Digikey part numbers attached to each part in the KiCad .sch files.

Pocket: common questions

What microcontroller does the Pocket use?

The Pocket is built around the Teensy4.1, from the NXP family.

How big is the Pocket PCB?

The Pocket measures 66 × 38.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pocket?

31 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pocket design files?

From the kwan3217/kicad repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Pocket design in my own project?

Yes, under the terms of its GPL-2.0 license, which kwan3217 chose for the repository.

Can I test firmware for the Pocket 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.
