Learning rmk: common questions

What microcontroller does the Learning rmk use?

The Learning rmk is built around the Raspberry_Pi_Pico, from the RP2040/RP2350 family.

How big is the Learning rmk PCB?

The Learning rmk measures 84 × 57.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Learning rmk?

19 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the Learning rmk design files?

From the Dreamy-Jy/learning_rmk repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Learning rmk design in my own project?

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

Can I test firmware for the Learning rmk 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.
