16 25: common questions

What microcontroller does the 16 25 use?

The 16 25 is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.

How big is the 16 25 PCB?

The 16 25 measures 56 × 65 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 16 25?

36 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the 16 25 design files?

From the robin48gx/TH7 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the 16 25 design in my own project?

The repository has no license, so all rights stay with robin48gx. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 16 25 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.
