ControlCircuit: common questions

What microcontroller does the ControlCircuit use?

The ControlCircuit is built around the Pico, from the RP2040/RP2350 family.

How big is the ControlCircuit PCB?

The ControlCircuit measures 191.9 × 88.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ControlCircuit?

124 components, from 38 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 ControlCircuit 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 ControlCircuit 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 ControlCircuit 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.
