ControlCardRP: common questions

What microcontroller does the ControlCardRP use?

The ControlCardRP is built around the RP2350B, from the RP2040/RP2350 family.

How big is the ControlCardRP PCB?

The ControlCardRP measures 53.5 × 49.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ControlCardRP?

179 components, from 57 distinct parts. The full bill of materials is listed on this page.

Where can I download the ControlCardRP design files?

From the abinash18/KBUltra repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ControlCardRP design in my own project?

Yes, under the terms of its GPL-3.0 license, which abinash18 chose for the repository.

Can I test firmware for the ControlCardRP 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.
