IjrX1Core: common questions

What microcontroller does the IjrX1Core use?

The IjrX1Core is built around the RP2040, from the RP2040/RP2350 family.

How big is the IjrX1Core PCB?

The IjrX1Core measures 320 × 255 mm, has 4 copper layers and is 1.24 mm thick.

How many components are on the IjrX1Core?

246 components, from 113 distinct parts. The full bill of materials is listed on this page.

Where can I download the IjrX1Core design files?

From the OpenNoorIlm/IjrX1Core repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the IjrX1Core design in my own project?

Yes, under the terms of its MIT license, which OpenNoorIlm chose for the repository.

Can I test firmware for the IjrX1Core 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.
