About the Loginator pihat PCB

Loginator pihat 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 65 × 56 mm, with 65 components from 42 distinct parts.

Its main chip is the LPC2148, from the NXP family. Other key parts include the BMP180, 3.3V, MCP73831, MPU6050 and HMC5883L. By type, the board carries 30 capacitors, 11 resistors, 8 ICs, 5 connectors, 4 switches and 4 diodes.

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.

Loginator pihat: common questions

What microcontroller does the Loginator pihat use?

The Loginator pihat is built around the LPC2148, from the NXP family.

How big is the Loginator pihat PCB?

The Loginator pihat measures 65 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Loginator pihat?

65 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the Loginator pihat 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 Loginator pihat 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 Loginator pihat 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.
