Interface: common questions

What microcontroller does the Interface use?

The Interface is built around the Pico_interface, from the RP2040/RP2350 family.

How big is the Interface PCB?

The Interface measures 106.8 × 107 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Interface?

105 components, from 23 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 Interface design files?

From the OisinS13/FC_IP_rig repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Interface design in my own project?

Yes, under the terms of its GPL-3.0 license, which OisinS13 chose for the repository.

Can I test firmware for the Interface without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
