Assignment2: common questions

What microcontroller does the Assignment2 use?

The Assignment2 is built around the TPS51386RJNR, from the RP2040/RP2350 family.

How big is the Assignment2 PCB?

The Assignment2 measures 50 × 50 mm, has 2 copper layers and is 1 mm thick.

How many components are on the Assignment2?

47 components, from 35 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 Assignment2 design files?

From the leomotors/pcb-design-assignment 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 Assignment2 design in my own project?

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

Can I test firmware for the Assignment2 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.
