PiPtr: common questions

What microcontroller does the PiPtr use?

The PiPtr is built around the RASPBERRY_PI, from the Raspberry Pi family.

How big is the PiPtr PCB?

The PiPtr measures 101.6 × 141.7 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the PiPtr?

379 components, from 64 distinct parts. The full bill of materials is listed on this page.

Where can I download the PiPtr design files?

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

Can I use the PiPtr design in my own project?

The repository has no license, so all rights stay with jmlzone. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PiPtr without the hardware?

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